Product details

23-position sealed header for harness-to-PCB interfaces

It uses a 4.00mm pitch and 0.157" row spacing, with a shrouded 4-wall design that protects the male pins during handling and mating. The header is sealed and includes a mounting flange, making it suitable for automotive and industrial environments where moisture and debris are present.

The 4.00mm pitch and 23-position count are the primary footprint and BOM match points — confirm the PCB layout and the mating receptacle's circuit count before ordering.

It is ROHS3 compliant and supplied in bulk packaging.
