The WB-51PAR is a right wedgelock accessory designed for the 102-way DEUTSCH DRB series receptacle connector. This secondary wedgelock component confirms proper contact alignment and offers keying options (A, B, C, D) within each connector to ensure correct mating orientation. The wedgelock is assembled at the mating interface and clicks into place, providing a secure mechanical lock that prevents misalignment and ensures reliable electrical connection. It is used in harsh environment applications where even small degradation in connection may be critical, such as engine, transmission, chassis, and cab installations in industrial and commercial transportation systems.
