Product details

20-position 2.50mm pitch XH header

The B20B-XH-A(LF)(SN) is a 20-position, single-row, shrouded header from JST's XH series, designed for board-to-cable/wire interconnect. The 2.50mm pitch packs 20 circuits into a compact footprint, and the 4-wall shroud protects the male pins during handling and mating.

Detent lock and shrouded construction

The detent lock engages with the mating XH receptacle housing, creating a positive latch that resists accidental disconnection under cable strain or vibration.

Frequently asked questions

What is the mating half for the B20B-XH-A(LF)(SN)?
