This module features an innovative quad coaxial, side-by-side structure. The rear panel interface matches the cable width, enabling direct soldering to header pins on the relay board or immediate tubing assembly—eliminating the need for secondary soldering. The lens module end integrates an LED within a compact 1.0x1.35mm footprint. This design supports fully automated pre-processing and welding, minimizing reliance on manual handling. The result is exceptional product consistency, higher yield rates, and the ability to meet cost-reduction targets for volume procurement.
