When engineers design a compact endoscope device, the camera module is not selected only by sensor resolution. The real design challenge is usually mechanical: how to place the lens inside a narrow probe, route the cable through a slim structure, keep the main board away from the front end, and still maintain stable image output.
The SF-OCHFA20-2500mm+SF-YL428-V1.1 is a 1.5mm-class separate USB endoscope camera module designed for OEM projects that require a compact imaging front end and flexible long-distance integration. With an OCHFA20 CMOS sensor, 0.5MP 720×720 output, 120° wide-angle lens, 5–50mm focusing range and 2.5m separate cable structure, it is suitable for medical visualization tools, veterinary devices, industrial inspection probes and compact embedded imaging systems.
The SF-OCHFA20-2500mm+SF-YL428-V1.1 is useful when an OEM device needs a very small camera head, but the system designer does not want to place the processing board directly at the probe tip.
Its separate structure allows the front-end lens module to enter narrow spaces, while the main board and USB output section can be placed in a more convenient area of the device. This makes it practical for slim probes, handheld instruments, portable inspection tools and customized endoscope systems.
In many compact endoscope devices, the most limited space is not inside the handle or control box. It is at the front end of the probe. If the camera head is too large, the entire device may fail to meet the required diameter, insertion depth or ergonomic design.
A separate endoscope camera module solves this problem by dividing the imaging front end and the output board into different physical locations. This gives engineers more freedom during mechanical design.
The benefits include:
For OEM projects, this is often more important than simply choosing a higher-resolution camera.
The SF-OCHFA20-2500mm+SF-YL428-V1.1 is best positioned as a compact separate USB endoscope camera module for OEM integration.
It is not designed as a general webcam or standard board camera. Its value is in helping device manufacturers build narrow-diameter imaging tools where the camera front end must remain small while the signal output section can be placed separately.
This makes the module suitable for:

Many endoscope devices need a slim probe. A larger integrated camera head may be difficult to insert into narrow spaces. The 1.5mm-class design helps reduce the front-end size and supports more compact device structures.
If the imaging board is too close to the probe tip, it can limit mechanical design. With a separate structure, the main board can be placed in the handle, control section or another protected area.
The 2.5m standard cable gives engineers more flexibility when designing long-reach inspection tools or systems where the camera head and output section need to be separated.
The 120° FOV helps capture a wider scene in narrow spaces. This is useful when the camera cannot be frequently repositioned or rotated during inspection.
The 5–50mm focusing range makes the module suitable for close-range observation rather than long-distance recognition. This fits many endoscope use cases where the camera is placed very close to the target area.
For medical device developers, this module can be evaluated for compact visualization devices where a small camera front end is required. It may be suitable for device-level observation tools, portable imaging systems and narrow-probe development.
Final medical compliance should be evaluated according to the complete device design and target market requirements.
Veterinary tools often require compact cameras for oral, ear, skin, cavity or small-animal inspection. The separate design and 1.5mm-class front end can support lightweight handheld devices.
Industrial equipment manufacturers can use this module for narrow-cavity inspection, small pipe inspection, mechanical structure monitoring and compact borescope-style devices.
Some embedded devices require only a compact visual acquisition unit, not a large camera board. This module can be evaluated where front-end size, cable routing and basic image output are more important than high-pixel imaging.
Before selecting this model, engineers should evaluate the following:
Confirm whether the device requires a 1.5mm-class camera head. If the probe space allows a larger camera, higher-resolution options may also be considered.
The 2.5m cable supports flexible layout, but the final routing path, bending requirement and mechanical protection should be reviewed during device design.
Because ultra-small structures have limited space, lighting should be evaluated based on the target application. External or separate illumination may be more practical than increasing the front-end diameter.
The main board should be placed where it can be protected and connected easily to the host system.
This model is better for close-range observation. If the target object is far away, another lens or camera module should be evaluated.
This product is suitable when your project needs:
Another product may be more suitable if your project requires:
In those cases, a larger-diameter endoscope camera module or customized structure should be evaluated.
For OEM integration, customers can discuss:
The final configuration should be based on the device structure, inspection distance, lighting environment and production plan.
When sending an inquiry, customers should provide:
Yes. The separate structure is useful for OEM projects where the imaging front end must stay compact while the main board is placed elsewhere in the device.
Yes. The 2.5m cable helps support longer device layouts and flexible routing, but the final cable path should be evaluated according to the equipment structure.
It is a 0.5MP 720×720 module. Its value is compact integration and wide-angle close-range observation, not high-pixel imaging.
It can be evaluated for medical visualization device development. Final compliance depends on the complete device design and target market requirements.
Illumination can be discussed based on project needs, especially when the device requires external light, flying-light design or a compact front-end structure.
The SF-OCHFA20-2500mm+SF-YL428-V1.1 is a practical choice for OEM projects that need a compact, separate and flexible 1.5mm USB endoscope camera module.
Its main value is not only the OCHFA20 sensor or 720×720 image output. The stronger value is the combination of small front-end structure, 120° wide-angle observation, 5–50mm close focusing range and 2.5m cable layout.
For medical, veterinary and industrial device manufacturers, this model can serve as a compact imaging core for customized endoscope devices, narrow-space inspection tools and portable visualization systems.
