This is a small industrial inspection OCHFA20 color sensor USB LED endoscope camera module, a high-performance imaging device specially designed for industrial precision inspection scenarios. In the field of industrial quality inspection, the biggest challenge is not the defect itself, but defects hidden in inaccessible gaps. Compared with the common problems of bulky lenses and limited fill light in traditional industrial endoscopes, it can easily penetrate ultra-fine gaps inside industrial equipment, micro pipelines and other areas that are difficult to reach by conventional testing tools. At the same time, through the extended LED wires and separate arrangement from the lens, on the premise of keeping the ultra-fine size of the lens unchanged, it provides uniform and interference-free fill light for dim industrial environments. The core of the module is equipped with OmniVision OCHFA20 CMOS sensor, which has 0.5MP pixels, supports 720×720 resolution and 720P@30FPS smooth image output, and can clearly capture subtle defects of industrial parts; the sensor size is only 1/18 inch, and the pixel size reaches 1.008 μm×1.008 μm, with excellent low-light imaging capability; matched with a 120° wide-angle lens, it can expand the coverage of a single inspection, improve inspection efficiency, and support manual focus function to accurately focus on the target inspection area. In terms of connection and integration, the module adopts a Separate design, connects to the decoder board through a USB 6PIN header, and finally outputs signals through a Type-C interface, supporting USB2.0 speed and UVC protocol. It can be seamlessly compatible with mainstream industrial operating systems such as Windows and Linux, realizing plug-and-play and conveniently adapting to various industrial testing equipment. The production process adopts high-precision SMT technology and AA process to ensure the stability and consistency of the product in complex industrial environments. It has also passed multiple international authoritative certifications such as CE, FCC, RoHS and Reach, complying with global industrial safety and environmental standards.

Product Advantage ◢

  1. Ultra-Fine Dimensions: The 1.05mm lens diameter enables effortless entry into ultra-narrow regions such as gear clearances in precision machinery, pin gaps in electronic components, and micro-branches of industrial piping, accommodating more high-precision industrial inspection requirements.
  2. Separate LED Supplemental Lighting: The LED and lens separation design allows flexible adjustment of lighting angles through extended wiring, providing uniform illumination in dark equipment interiors and deep piping to ensure clear, distinguishable inspection images.
  3. High-Performance Imaging: The OCHFA20 sensor's 1.008μm×1.008μm pixel size enhances imaging quality in low-light environments, while the 720P@30FPS output frame rate captures details during dynamic inspection processes.
  4. Diverse Compatibility Options: The USB 6PIN+Type-C connection scheme ensures stable and reliable data transmission, USB 2.0 speed guarantees smooth data flow, and UVC protocol enables plug-and-play functionality for rapid integration with various industrial terminals. Compatibility with mainstream operating systems reduces equipment integration costs.
  5. Industrial-Grade Reliability: SMT and AA processes ensure precise component assembly, enhancing product stability under complex working conditions. Multiple international authoritative certifications validate compliance with industrial safety and environmental requirements.


Application of Endoscope Camera Module

  • Heat Exchanger Inspection: Used for examining fine tubes in power generation boilers, pilot holes in natural gas control valves, or micro-piping in chemical heat exchangers. The module adapts to high-temperature, high-humidity pre-inspection environments, helping identify internal scaling, cracks, or corrosion initiation points.
  • PCB Solder Joint Detection: For micro-hole inspection in high-density PCBs and hidden defect detection in BGA package solder joints, the lens penetrates PCB micro-vias while the Separate LED illumination avoids interference from solder joint metal reflections, clearly identifying defects such as cold joints and solder residue to ensure electronic product quality.
  • Aerospace Component Inspection: For detecting minute cracks in aircraft engine blades and fine-seam defects in aerospace precision structural components, the ultra-fine lens enters narrow assembly gaps while the wide field of view rapidly covers inspection areas and high-performance imaging accurately captures micron-level defects.
  • Precision Component Maintenance: Suitable for overhauling precision components, the lens passes through small oil passages in fuel injectors and narrow pipelines in transmissions. The Separate LED operates stably in oily environments, clearly presenting issues such as channel blockages and part wear.
  • Industrial Narrow-Pipe Detection: For internal inspection of ultra-fine industrial pipelines in chemical and water conservancy applications, the lens can traverse the entire pipe length. The 120° wide field of view covers the inner pipe walls, clearly detecting corrosion, scaling, and leak points to ensure safe operation of industrial piping systems.

FAQ◢

1. Is this module compatible with my industrial control system?

Yes. It supports UVC protocol and is seamlessly compatible with mainstream industrial operating systems such as Windows and Linux, realizing plug-and-play without installing special drivers.


2. Is the 1.05mm diameter the smallest available for this resolution?

Yes. At 720P resolution and 1/18-inch sensor size, 1.05mm is the engineering limit for commercial production while maintaining image quality and Separate LED capability.


3. How does the Separate LED design benefit us compared to traditional integrated LEDs?

It prevents heat buildup at the lens tip (extending sensor life), allows flexible lighting angles to avoid glare on metal surfaces, and enables independent LED replacement.


4. Can the module function without the LED attachment for well-lit inspections?

Absolutely. The LED is optional. The OCHFA20 sensor's 1.008μm pixels provide excellent low-light performance, but you can add or remove the Separate LED component based on your environment.
