The waterproof rating means the mated pair can handle washdown environments, which is unusual for a shrouded header in this class.
A built-in board guide aids alignment during assembly. The 4-wall shrouding protects the pins from accidental shorting during handling.
The latch holder and IP-rated construction make it a candidate for environments with moisture exposure or moderate vibration — think washing machine control boards, automotive lamp harnesses, or outdoor HVAC controls.
The mating pitch is 0.197" (5.00 mm). This determines the PCB footprint and the matching receptacle family.
Yes, it uses a latch holder fastening type for positive retention when mated with the WPJ receptacle housing.
This header mates with the corresponding WPJ series receptacle housing (crimp-style, sold separately). The latch holder on the header engages with the receptacle's locking feature.
It is a through-hole solder termination header with a 0.130" post length.
The (LF)(SN) suffix in the order code indicates lead-free and tin-plated termination, consistent with RoHS compliance requirements.
