Product details

12-position dual-row header for wire-to-board power

The header mates with Ultra-Fit receptacle housings (same series) using a latch holder fastening system that provides a positive lock against vibration.

The 3.50 mm pitch and 0.181" (4.60 mm) row spacing define the PCB footprint. Mated stack height is 26.99 mm, which sets the clearance needed between boards or between the board and enclosure wall. The kinked solder tails (0.126" post length) provide retention during wave soldering before the solder solidifies.

Supplied in bulk packaging.
