Introduction
Customers evaluating the SF-SJYL7-FT+SF-SJN73310 usually want to know more than the model number. They care about whether the 3.3mm camera head can fit their device, whether 1MP image quality is enough, whether the LEDs are useful in real cavities, whether the 102° FOV matches their working distance, and whether the optional shutter button can improve user operation.
This FAQ answers common buyer questions before sample testing and OEM project evaluation.
1. What is the SF-SJYL7-FT+SF-SJN73310?
The SF-SJYL7-FT+SF-SJN73310 is a 3.3mm separate-type USB endoscope camera module using the OV9734 1MP sensor. It supports MJPEG 1280×720@25fps output, integrates 6pcs 0201 LEDs and supports a 10–70mm focusing range.
2. What is the main value of this model?
Its main value is the balance between compact diameter, 1MP image output, built-in LED illumination, 102° FOV and optional shutter button support.
It is suitable for customers who need a small illuminated endoscope camera module for close-range observation.
3. What type of customer is this module suitable for?
It is suitable for OEM customers developing compact medical visualization devices, dental inspection tools, veterinary endoscope devices, industrial inspection tools, portable USB endoscopes and handheld visual inspection equipment.
4. Is this a finished endoscope device?
No. It is an endoscope camera module for OEM integration.
Customers still need to evaluate housing, cable routing, host system, mechanical protection, waterproof structure if required and final device assembly.
5. What is the camera head diameter?
The camera head diameter is D3.3.
This makes it suitable for compact devices that require a smaller front-end structure than larger 5mm or 6mm camera modules.
6. What sensor does it use?
It uses the OV9734 sensor.
This sensor provides 1MP-class imaging and is suitable for compact visualization applications that need better image detail than low-resolution micro modules.
7. What is the output resolution and frame rate?
The module supports MJPEG output at 1280×720@25fps.
This is suitable for general close-range observation and compact inspection devices. If the project requires 60fps or higher frame rate, another model should be evaluated.
8. Is 1MP enough for my application?
It depends on what the user needs to see.
1MP may be enough for general visualization, cavity observation, dental or veterinary inspection, device guidance and basic industrial checking. It may not be enough for fine defect detection, measurement-level inspection, AI recognition or high-resolution documentation.
9. Does this module have built-in LEDs?
Yes. It includes 6pcs 0201 LEDs.
This helps provide local illumination in dark or enclosed spaces, which is a common requirement for endoscope applications.
10. Can the LED brightness be adjusted?
According to the catalog, dimming is marked as No.
If the project requires adjustable LED brightness, customers should discuss alternative module options or customized lighting design with SincereFull before sample confirmation.
11. Why is LED dimming important for some projects?
Some surfaces reflect strongly, especially wet, shiny or curved surfaces. In these cases, fixed LED brightness may create overexposure or reflection.
If brightness control is important, customers should mention this requirement during RFQ.
12. What is the field of view?
The module has a 102° field of view.
This helps users see more surrounding area inside a compact space, especially during close-range inspection.
13. Is 102° FOV always better?
Not always.
A wider FOV helps show more context, but if the application needs focused detail on a small target area, a different FOV may be more suitable. Customers should test the FOV in the real working environment.
14. What is the focusing range?
The focusing range is 10–70mm.
This means the module is more suitable for close-range to medium-close observation. Customers should test it at the actual working distance of the final device.
15. Is this module suitable for very short-distance viewing below 10mm?
It may not be the best fit if the application requires clear viewing below 10mm.
Customers should provide the target working distance so SincereFull can evaluate whether this model or another module is more suitable.
16. Is it suitable for viewing beyond 70mm?
This model is specified with a 10–70mm focusing range.
If the project needs longer viewing distance, another lens or camera module should be evaluated.
17. Does it support IP67 waterproof design?
The catalog does not clearly mark this model as IP67.
Customers who require waterproof performance should discuss device-level sealing requirements or evaluate another IP67-supported module.
18. Can it be used in a waterproof final device?
It may be used inside a customer-designed sealed structure, but final waterproof performance depends on the complete device design, including housing, sealing, cable exit and assembly process.
Customers should not assume module-level IP67 unless confirmed.
19. What is the optional shutter button used for?
The optional shutter button can be useful for handheld or portable devices where users need to capture images during inspection.
It may help improve workflow by reducing the need to operate the host device every time an image needs to be saved.
20. Does the shutter button work with every system?
Not necessarily.
Shutter button function should be confirmed based on the host system, software, connection method and final device design. Customers should mention this requirement before sample testing.
21. What is the standard cable length?
The standard cable length is 1m.
Customers should confirm whether 1m is enough for their device structure and user operation.
22. What is the main board size?
The main board size is 28×12mm.
This compact board size is useful for OEM integration, but customers still need to check whether it fits inside their handle, control box or device housing.
23. What connector layout does this model use?
The catalog lists a Type-C / 5-pin connection layout.
Customers should confirm the exact connector arrangement, cable direction and host compatibility before finalizing the device design.
24. Is this module suitable for dental inspection devices?
It can be evaluated for compact dental or oral inspection devices if the 3.3mm diameter, 10–70mm working distance, LED brightness and image quality match the application.
If higher detail is required, customers may need to compare it with higher-resolution modules.
25. Is this module suitable for veterinary endoscope devices?
Yes, it can be evaluated for compact veterinary visualization devices.
The final choice should depend on target application, working distance, image detail requirement, lighting condition and device structure.
26. Is this module suitable for industrial borescopes?
It can be evaluated for compact industrial borescope or narrow-cavity inspection tools, especially when built-in lighting and a small camera head are needed.
For harsh environments, customers should confirm mechanical protection and waterproof requirements separately.
27. Is this module suitable for AI inspection?
It is generally not the first choice for AI inspection.
For AI recognition, measurement or defect detection, customers usually need higher image detail, stable lighting control and sometimes a different sensor platform.
28. What should customers test first after receiving samples?
Customers should test:
Image clarity at 10–70mm distance
LED brightness in the real cavity
Reflection on the target surface
102° FOV in the final use scene
Shutter button function if required
Cable routing
Board placement
Host compatibility
Mechanical protection
29. What is the most common mistake when choosing this model?
The most common mistake is choosing it only because it has a 3.3mm diameter and 1MP sensor.
Customers should also check working distance, lighting, FOV, cable length, board size, waterproof needs and shutter button compatibility.
30. Can SincereFull customize this module?
Project-level customization or alternative module evaluation can be discussed based on diameter, lens, FOV, LED, cable, connector, shutter button, housing and mechanical structure requirements.
Any change affecting optical performance, lighting, waterproof design or production feasibility should be reviewed before confirmation.
