The Molex 502351-0400 is a compact 4-circuit wire-to-board receptacle housing from the Molex DuraClik 2.00mm connector family, designed for reliable wire harness-to-PCB connections in space-constrained electronic systems.
The housing uses a single-row, 4-position configuration with a 2.00mm mating and termination pitch. Its compact design is suitable for applications where connection density, mechanical retention and reliable mating are important.
The 502351-0400 incorporates keying, polarization and locking features to help prevent incorrect mating and improve connector retention. These features make the DuraClik system particularly useful in equipment exposed to vibration, repeated handling or demanding operating environments.
The housing is manufactured from polyester alloy resin, supplied in a natural color, and features an unsealed construction. It supports an operating temperature range of -40°C to +105°C and is supplied in bag packaging.
When assembled with compatible DuraClik terminals and mating headers, the standard DuraClik connector system supports ratings of up to 3.0A and 125V, depending on terminal, wire gauge and actual application conditions.
The 502351-0400 is the receptacle housing component of the connector system. Appropriate crimp terminals and mating PCB headers should be selected separately according to the required wire size and application.
