Automotive Waterproof Connectors Receptacle Housing of 2.5mm Pitch

Most industrial waterproof connectors are oversized, hard to assemble and costly. HRB 2.5mm pitch right angle wire to board waterproof connector (Model M2532/M2531R) is developed as a mini-size low-cost waterproof interconnect solution for automotive & outdoor electrical systems.

With IP67 waterproof and dustproof grade, solid rubber sealing and double locking mechanism, it guarantees stable sealing and anti-loosening performance under vibration, humidity and temperature fluctuation. Multiple pin counts from 2×9 to 2×20 satisfy diversified wiring demands of automotive cameras, vehicle batteries, electric two-wheelers and outdoor machinery.
