3.9mm 720P USB Endoscope Camera Module Series for Inspection

This series is designed for compact visual inspection equipment that needs a 3.9mm direct-view probe, close-range illumination and USB video output. It includes two function-focused models rather than one general-purpose configuration:

• SF-C1011USB-D3.9-720P60 uses the OmniVision OH01A10 sensor and supports 720P video at up to 60fps. Its 10–80mm focus range and 85° diagonal field of view suit inspection tasks where motion response and shorter working distances are priorities.

• SF-C1019USB-D3.9-PLUS uses the OmniVision OV9734 sensor and supports 720P video at up to 30fps. Its 95° diagonal field of view and 10–100mm focus range provide broader coverage and more working-distance flexibility.

Both models use a separated probe-and-processing-board structure. This allows the 3.9mm lens head to enter a narrow cavity while the larger processing board remains outside the restricted area. Four front-mounted 0402 LEDs provide local illumination, while USB 2.0 UVC output supports host-side evaluation on compatible systems.

For other probe constructions, interfaces and optical combinations, compare the wider 3.9mm endoscope camera module range.

Whichever you choose, the Series provides an uncompromising imaging foundation:

• 3.9mm Steel-Shell Probe: The compact head can enter narrow channels, mechanical gaps and probe housings that cannot accommodate a larger camera diameter. The enclosure design should allow for manufacturing and assembly tolerances.

• Two Purpose-Built Imaging Options: Select 60fps output for motion-sensitive inspection or choose the wider 95° diagonal view and 10–100mm focus range for broader observation.

• 720P USB Video Output: Both models provide 720P-class imaging through a USB 2.0 UVC architecture, reducing the need for a model-specific host video driver during evaluation.

• Four Integrated 0402 LEDs: Front-mounted LEDs provide illumination close to the viewing direction for dark cavities. LED brightness and control method should be confirmed for the selected configuration.

• IP67-Rated Probe Head: The sealed steel-shell probe is designed for dusty and temporary water-exposure conditions. Protection of the final device still depends on the cable entry, connector and enclosure assembly.

• Separated Mechanical Structure: The probe and processing board can be positioned in different areas of the device, giving OEM engineers more freedom when routing the cable and arranging host-side electronics.

• SMT and Active Alignment Assembly: SMT production and AA optical alignment support controlled positioning of the sensor and lens during module assembly.

1. SF-C1011 for 60fps Inspection

The SF-C1011USB-D3.9-720P60 is the better starting point when inspection involves movement or repeated changes in component position. Its OH01A10 sensor supports 720P output at up to 60fps, recording more frames during the same period than a 30fps configuration. This can make motion easier to follow and gives software more image samples for review.

Typical evaluation scenarios include:

• Monitoring the movement of small mechanisms or internal components

• Checking operating status inside compact equipment

• Observing assembly steps where the target position changes frequently

• Inspecting parts at working distances between approximately 10mm and 80mm

• Evaluating compact visualization equipment that benefits from smoother live video

The 85° diagonal field of view keeps the image more focused than the wider PLUS model. Choose this version when motion continuity and medium-short working distance are more important than maximum scene coverage. Final motion clarity should be tested with the intended target speed, exposure, lighting and host software.

For medical or veterinary visualization development, this module is supplied as an imaging component rather than a finished clinical device. The equipment manufacturer remains responsible for device-level image validation, thermal safety, electrical safety, cleaning or sterilization compatibility, software, EMC and regulatory compliance.

2. SF-C1019 for Wider and Deeper Viewing

The SF-C1019USB-D3.9-PLUS is intended for inspection tasks where the operator needs to see more of the surrounding area or work at a slightly longer distance. Its OV9734 sensor supports 720P@30fps, while the 95° diagonal field of view and 10–100mm focus range provide broader coverage than the 60fps model.

Typical evaluation scenarios include:

• Observing larger sections of an internal pipe or channel

• Viewing hidden construction spaces and deeper cavities

• Checking the assembly condition of internal automotive or mechanical parts

• Examining mold cavities and other recessed surfaces

• Reducing repeated probe repositioning when broader context is useful

Choose this version when viewing width and working-distance flexibility take priority over 60fps output. Because a wider lens places more of the scene into one frame, the smallest details should be evaluated at the actual display size and target distance before the optical configuration is approved.

For damp, dusty or splash-prone industrial applications, treat IP67 as a probe-head specification rather than automatic protection for the complete device. The finished cable entry, connector, handle and enclosure should be sealed and tested as an assembled system.
