Product details

20-Position Shrouded Header with Locking Ramp

The 2.50mm pitch and 0.205" (5.20mm) row spacing define the PCB footprint, while the 4-wall shrouding and locking ramp provide keyed, vibration-resistant mating.

Mating Half and Termination Checklist

This header mates with a Multi-Lock receptacle housing (sold separately) using tab contacts with rectangular form. Termination is through-hole solder: the 0.146" (3.70mm) post length and 0.276" (7.00mm) mating contact length are fixed. The mounting flange provides additional mechanical retention to the PCB.

Supplied in tube packaging.
