Product details

2.00 mm pitch, 4 positions, shrouded latch — what it is

The B04B-JWPF-EK-R: The through-hole termination uses kinked pins for solder retention, and the mating contact finish is tin — good for moderate cycle life in cost-sensitive builds.

IP-rated seal and latch holder for washdown environments

The header carries a dust-tight, waterproof ingress protection rating — unusual for a pin header — meaning the mated pair can handle occasional splashes or dust exposure.

The closest functional second-source is the B04B-JWPF-SK-R(LF)(SN) — same 4 positions, 2.00 mm pitch, same tin-plated contacts and IP rating. The only difference is the suffix; the EK-R variant uses a different latch or packaging detail. Both are active.
