2.0mm OCHFA10 IP67 Waterproof Ultra-Micro USB Endoscope Camera Selection Guide

In micro-pipeline inspection, precision micro-component quality control, minimally invasive medical exploration, and portable micro-detection equipment development, imaging system selection often faces multiple constraints: probe diameter must be less than 2.5mm to enter micro-channels, and the module must also be waterproof to withstand moisture, liquid splashes, or even temporary immersion. When conventional endoscopes are either too large or lack waterproofing, a module based on the OCHFA10 Camera Module with a diameter of just 2.0mm, IP67 waterproof steel shell, 86° ultra-wide angle, and USB UVC driver-free operation becomes a critical solution for breaking through inspection barriers in extreme spaces and harsh environments. This article provides a clear selection framework from five dimensions—physical size, environmental protection, optical performance, interface protocol, and typical applications—while incorporating key terms such as endoscope camera module, OCHFA10 Camera Module, usb endoscope camera, HD Camera Module, 2mm Diameter, mini Camera Module, Driver Free, UVC Camera Module, Wide Angle Camera Module, and CMOS Camera Module to help you precisely match micro-space waterproof inspection needs.

1. Physical Size: Verifying the 2.0mm Micro Probe’s Accessibility

Step 1: Precisely measure the minimum inner diameter and bend radius of the target channel.

The probe diameter is only 2.0±0.05mm (2mm Diameter), representing an extreme miniaturization design among mini Camera Module products. Engineering significance:

• Easily accesses micro-catheters, microfluidic channels, precision mechanism gaps, and natural body orifices with inner diameter ≥2.2mm, covering most “sub-millimeter” narrow spaces in medical, electronics, and micromachinery fields.

• Compared to 3mm+ probes, 2.0mm extends the detectable range downward by 1mm, suitable for many medical puncture needles (though 18G ~1.3mm requires even smaller, but for ≥2.2mm channels it is ideal).

• The separate design (1.5m flexible cable) makes the front end extremely small and light, facilitating navigation through tortuous paths; the rear circuit can be placed away from the inspection area.

When selecting, verify: Is channel inner diameter ≥2.2mm? For sharp 90° bends, evaluate the probe’s rigid section length (typically 3-5mm) and cable bend radius. Custom cable lengths are available.

2. Environmental Protection: Industrial-Grade Reliability of IP67 Waterproof Steel Shell

Step 2: Assess risks of liquid contact, dust, and disinfection requirements.

This module features a stainless steel shell with IP67 waterproof rating, fully dust-tight and capable of withstanding immersion in 1 meter of water for 30 minutes. Engineering value:

• Suitable for wet pipes, medical disinfectant wipe-down, outdoor rain, short-term underwater inspections, etc.

• The steel shell also provides drop and crush resistance, ideal for frequent mobile field use.

• IP67 rating enables use in medical auxiliary equipment requiring wash-down disinfection or food industry inspections.

Note: IP67 is not suitable for high-temperature liquids (>50°C) or high-pressure water jets; for autoclave sterilization, confirm sealing material compatibility. For dry, clean environments, a non-waterproof version may be available, but this module comes standard with waterproofing. The steel shell can be corrosion-treated for oil and chemical resistance.

3. Optical Performance: 86° Symmetric Wide Angle and 5–50mm Macro Focus

Step 3: Confirm working distance, field coverage, and detail resolution requirements.

This module incorporates the OCHFA10 Camera Module based on CMOS Camera Module technology, providing an 86°×86° symmetric field of view (Wide Angle Camera Module characteristic), distortion < -11%, 5–50mm dedicated macro focus, and 0.418mm focal length. Core value:

• The 86° symmetric ultra-wide angle achieves a square field within a 2mm diameter, covering a large area at working distances of 5-20mm, capturing the entire cross-section of micro-holes or small pads in a single frame, effectively reducing blind spots.

• The 5–50mm focus range precisely covers typical macro inspection distances, delivering clear images without frequent focusing, especially suitable for probe position-constrained scenarios.

• Although resolution is not explicitly stated, the OCHFA10 typically outputs around 700×700 (approximately 0.5MP), making it a lightweight HD Camera Module, sufficient to resolve 0.05mm-level micro-scratches, foreign objects, and solder joint morphology.

As a practical Wide Angle Camera Module, this module balances miniaturization and field width. Note: Distortion < -11% (barrel) is acceptable in ultra-wide-angle endoscope designs, expanding peripheral vision; for precision measurement, software correction can be applied. The 5mm minimum focus distance meets most macro observation needs.

4. Interface and Protocol: USB UVC Driver-Free Plug-and-Play

Step 4: Evaluate host platform compatibility and development efficiency.

This module uses a Micro USB-5P interface, incorporates the standard UVC Camera Module protocol, and supports Driver Free plug-and-play without driver installation. As a usb endoscope camera, key advantages:

• Cross-platform compatibility: Automatically recognized by Windows, Linux, Android (with OTG), macOS, etc., allowing direct connection to laptops, tablets, or industrial PCs.

• Zero driver development: Significantly shortens time-to-market for medical or inspection equipment manufacturers.

• The separate design’s rear circuit outputs directly via USB, simplifying overall device design.

When selecting, verify: Does the target host’s USB port provide adequate power (5V/500mA is sufficient)? For long-distance transmission (>5m), use active USB extension cables. The module includes 4 integrated LEDs for fill light, with low power suitable for battery operation.

5. Typical Application Scenarios and Selection Recommendations

6. Selection Decision Summary

The core value of the 2.0mm OCHFA10 IP67 waterproof ultra-micro USB endoscope module lies in combining the extreme miniaturization of the OCHFA10 Camera Module, the 86° symmetric wide angle of the Wide Angle Camera Module, the plug-and-play convenience of the UVC Camera Module, the cross-platform compatibility of the usb endoscope camera, and the rugged protection of the IP67 waterproof steel shell—providing a cost-effective, high-reliability vision solution for micro-pipelines, precision micro-components, minimally invasive instruments, and portable micro-detection devices. When selecting, prioritize three questions:

• How narrow is the space? If channel inner diameter ≥2.2mm, the 2mm Diameter probe fits; if smaller, custom an even smaller diameter (feasibility depends on sensor limits).

• Is waterproofing needed? For wet, liquid-contact, or disinfectant environments, IP67 is mandatory; for dry scenes, non-waterproof versions may reduce cost.

• Is the working distance within 5–50mm? Fixed macro focus requires no adjustment; if distances vary widely, consider auto-focus or varifocal options.
