Product details

Board-to-Wire Header for XA Series

The S04B-XASK-1(LF)(SN): It mates with the XA crimp-style receptacle housing to form a locked, vibration-resistant connection.

Termination is press-fit, solder — the header is inserted into plated through-holes and wave-soldered. The 0.126" (3.20 mm) post length provides sufficient stand-off for a clean solder fillet on the opposite side. Natural (white) insulation color aids visual inspection of solder joints and mating alignment.
