The Visionstar SJD-C14A is a battery-powered dental X-ray generator weighing 2.2 kg net and measuring 180 × 140 × 140 mm. It operates at 60 kV and 1.2 mA from a 30 kHz generator rated at 60 VA, with exposure timing from 0.1 to 2.5 seconds. Power comes from a DC 16.8 V, 2300 mAh lithium pack.

The control face is a touch panel, and its layout is the point of interest. Maxillary and mandibular tooth positions occupy separate rows, so an operator identifies the arch first and the position within it second, alongside adult and child mode selection and direct plus and minus adjustment of the exposure time. That mirrors how a clinician describes a view when writing it in the notes, which makes the selection sequence short and the training conversation straightforward.

The manufacturer also publishes an exposure time reference table covering eight tooth positions for both patient groups, with distinct film and sensor columns. Treat those as starting values for discussion with your Medical Physics Expert rather than as a protocol. Optimisation under IR(ME)R 2017 is performed for your equipment, your receptors and your patient mix, and the values that govern your practice are the local diagnostic reference levels your MPE agrees. Confirm at order whether the stored values behind each selection can be edited.

Focal spot to skin distance is published at 100 mm, which matches the minimum commonly cited in UK guidance for equipment operating at 60 kV and below. Note that the tube's own nominal operating voltage is stated as 70 kV, so ask the manufacturer to confirm that unit output is fixed at 60 kV and cannot be configured higher — above that threshold, the longer minimum distance applies.

The tube carries a tungsten target at a 19° target surface angle, with a stated anode heat capacity of 9 kJ and a fluoroscopy load of 150 W. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-C14A across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-C14A is configured for that daily volume. It supports bitewing caries detection, periapical assessment of pathology, endodontic working-length and obturation verification, alveolar bone-level review, and root morphology assessment ahead of extraction.

Arch-based selection suits the way clinical records are written. A view is described by arch and position, and a control face organised the same way keeps the operator working in clinical terms throughout. Where several clinicians, therapists and nurses share one unit, that shared structure keeps technique consistent and makes image quality audit findings point to the protocol.

Paediatric practice is served by the separate adult and child modes. Reduced exposure factors for smaller patients become an explicit selection at the control face, with the values themselves agreed with a Medical Physics Expert and recorded as local diagnostic reference levels. Community dental services carry much of that caseload.

Practices running mixed receptor types benefit from the distinct film and sensor columns in the manufacturer's reference table, which address each separately rather than collapsing them into a single figure.

Community and special care teams need equipment one clinician can carry. At 2.2 kg net, the unit travels, though the published operating range of 10 to 40 °C is worth noting for domiciliary work in unheated buildings, and off-site radiation protection arrangements need to be agreed with the RPA in advance.

Guidance from the College of General Dentistry and UKHSA Dental X-ray Protection Services remains the reference point UK practices work to, alongside HSE enforcement of IRR17.

Selection in clinical terms

Arch first, position second — the same order a clinician uses when describing or recording a view. That removes a translation step between intention and machine setting.

Consistency across a shared team

Where several operators use one unit, a shared selection structure means everyone reaches the same setting for the same view, which keeps technique consistent and makes audit findings actionable.

Paediatric factors as an explicit choice

Separate adult and child modes make reduced exposure for smaller patients a deliberate selection at the control face, with the values agreed with your Medical Physics Expert.

Film and sensor addressed separately

The manufacturer's reference table gives distinct columns for each receptor type, which suits practices running both across surgeries or working through a phased change.

Focal spot to skin distance published

A stated 100 mm figure lets your Radiation Protection Adviser assess the geometry at specification rather than measuring it after delivery.

Full tube parameters disclosed

Target material, target surface angle, fluoroscopy load, filament parameters and heat capacity are all published, giving your RPA and service engineer a complete picture of the tube before order.

Direct exposure time adjustment

Plus and minus controls sit alongside the position selection, so a value can be nudged from the selected starting point without leaving the working screen.

Data sheet questions surfaced before order

Two focal spot figures, filtration stated for the tube rather than the beam path, and a 220 V charger input all need clarifying. Medigear.uk can arrange for each to be put to the manufacturer with your quotation.

Maxillary and mandibular position rows

Upper and lower arch positions occupy separate rows on the control face, so the arch is identified before the position within it.

Adult and child mode selection

Patient group is selected directly, with the associated exposure value presented for the chosen position.

Touch control panel

A touch-operated screen carries status, battery indication, exposure time and the selection rows on one continuous surface.

Direct exposure time adjustment

Plus and minus controls raise or lower the exposure time from the selected starting value without leaving the screen.

Printed exposure time reference table

Reference values are published for eight tooth positions and both patient groups, with separate film and sensor columns — a starting point for protocols agreed with your MPE.

60 kV tube voltage

Operation at 60 kV sits within the established kilovoltage range for intraoral dental radiography and at the threshold governing minimum focus-to-skin distance.

1.2 mA tube current

Published tube current, with exposure time as the variable setting the exposure product for each region and receptor type.

0.1–2.5 second exposure range

A twenty-five-fold span reaching short sensor values at one end and film technique at the other.

100 mm focal spot to skin distance

Published distance, matching the minimum commonly cited in UK guidance for sets operating at 60 kV and below.

Tungsten target at 19° target surface angle

Published target material and angle, both relevant to beam output and to the intensity distribution across the field.

9 kJ anode heat capacity, 150 W fluoroscopy load

Published thermal figures; ask the manufacturer for the cooling curve where sessions routinely run long.

DC 16.8 V, 2300 mAh battery

An integrated lithium pack with published capacity, charged from the supplied adapter.

Silicone hand strap

An integrated strap supports single-hand carrying and steadier beam alignment while the exposure is taken.

180 × 140 × 140 mm at 2.2 kg net

Published product dimensions and net weight, alongside a 310 × 275 × 255 mm carton at 4.1 kg gross.

The Visionstar SJD-C14A gives UK dental teams a 2.2 kg battery-powered X-ray generator organised around separate maxillary and mandibular position rows with adult and child mode selection, running 60 kV / 1.2 mA from a 30 kHz generator with a 0.1–2.5 second exposure range, a published 100 mm focal spot to skin distance, a tungsten target at 19° and a DC 16.8 V 2300 mAh battery. It fits NHS and private general practice, paediatric and special care dentistry, community dental services, multi-operator and teaching settings, and practices running mixed film and sensor workflows. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation, service cover and planned maintenance across the United Kingdom, and can arrange for the manufacturer's focal spot clarification, total filtration and half-value layer data, charger voltage rating and preset editability to accompany your quotation for your Radiation Protection Adviser's review. Contact the Medigear.uk team for pricing, lead times, sensor pairing options and configuration enquiries.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

It shortens the path from clinical intention to machine setting. A clinician thinks and records in terms of arch and position — upper left second premolar, lower right molar — so a control face laid out the same way removes a translation step. On a shared unit, every operator then arrives at the same setting for the same view, which keeps technique consistent across a team.

Settle this before order. The main table states a tube focus of 0.3 mm × 0.3 mm, while the tube parameter block gives a nominal focal spot value of 0.8. Focal spot size governs geometric unsharpness at the receptor, so the difference matters both for the detail the unit resolves and for the assessment your Radiation Protection Adviser and Medical Physics Expert carry out. Ask the manufacturer which figure describes the unit as supplied and get it in writing. Medigear.uk can arrange for that clarification with your quotation.

Not as a total. The tube parameter block lists filtration of 1 mm aluminium, which reads as the tube's own contribution rather than the filtration of the complete beam path. Total filtration is what a Radiation Protection Adviser assesses beam quality from, and 1.5 mm aluminium equivalent is the minimum commonly cited for intraoral sets operating up to 70 kV. Request the total filtration figure and the half-value layer data, and have your RPA review both before the unit enters service.

For operation at 60 kV, it matches the minimum commonly cited in UK guidance for that band, so it is consistent with how the unit is specified. Two points follow. It sits at the minimum with no margin, so give your RPA the figure explicitly. And because the tube is rated at a nominal 70 kV, confirm the unit cannot be configured above 60 kV — if it can, the longer minimum distance applies, and the supplied applicator would need to deliver it.

It describes how much energy the anode absorbs before a cooling interval is needed. Energy per exposure is approximately tube voltage multiplied by current and time, so a maximum-length exposure here comes to roughly 180 joules and a routine short one to a small fraction of that. On that basis, a 9 kJ anode covers a substantial run of ordinary exposures. The anode also cools continuously between shots, so the working limit depends on duty cycle rather than simple division — ask the manufacturer for the cooling curve if your sessions run long.

Raise it before ordering. The data sheet specifies a charger input of 220 V at 50 Hz rather than a wide 100–240 V range. UK mains is nominally 230 V with a tolerance band extending above that, so ask the manufacturer to confirm the supplied charger is rated across the full UK supply range, and whether a wide-input adapter can be provided instead. It is a small question that is far easier resolved before delivery.

As an informed starting point, not as your protocol. The published values cannot reflect your receptor speed, your collimation, your total filtration or your patient mix. Take them to your Medical Physics Expert, agree the values that suit your installation, record those as local diagnostic reference levels, and audit image quality against them at the interval your Radiation Protection Adviser sets.

The Ionising Radiations Regulations 2017 require employers carrying out dental X-ray work to register with the Health and Safety Executive, appoint a Radiation Protection Adviser, nominate a Radiation Protection Supervisor and complete a radiation risk assessment. The Ionising Radiation (Medical Exposure) Regulations 2017 add the appointment of a Medical Physics Expert, justification and optimisation of each exposure, and documented training for referrers, practitioners and operators. A critical examination is required when the equipment is put into service.

Dental X-ray equipment is subject to routine quality assurance and periodic radiological testing under IRR17, alongside annual electro-mechanical inspection, with a critical examination required at installation. UK service providers commonly apply an annual radiological testing interval to hand-carried units. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months for this equipment class — confirm the term, the parts covered and the battery position at quotation.
