Product details

Board-to-Wire Header for 5-Circuit Harnesses

The B05B-XASK-1(LF)(SN): The 2.50mm pitch sets a moderate board footprint — wide enough to route a single trace between pads on a standard 1oz copper layer, and the 250V rating covers most low-voltage DC and AC signal rails.

Through-Hole Retention for Cable Strain

Through-hole mounting gives this header stronger mechanical anchorage than an SMT part — important when the mated cable assembly is routed near the board edge and subject to tugging during assembly or service.

Mating Housing and Stack Height

Mated stack height is 11.3mm — measure the clearance from the PCB surface to the inside of the enclosure lid or adjacent board before committing the layout.
