Product details

Mating Connector and Harness Planning

The B12B-PASK-1(LF)(SN): For a 12-circuit harness, order the matching PA receptacle housing (e.g., JST part number 12P-SFN or similar PA-series 12-position housing) and the appropriate crimp terminals (SPHD-001T-P0.5 or equivalent).

Stack Height and Board Spacing Options

Three mated stack heights are listed: 9.9 mm, 14.7 mm, and 14.9 mm — the variation comes from different PA receptacle housing depths. This lets the same header serve multiple enclosure z-height budgets without a board layout change.

Frequently asked questions
