20-Position, 5-Row Receptacle Housing for High-Pin-Count Harness Assemblies
The TE Connectivity NTS 2350891-2 is a 20-position, 5-row receptacle housing designed for panel-mount applications where a dense, multi-row interconnect is needed. It accepts tab-type crimp contacts (sold separately) and secures them with a locking ramp and a terminal position lock (TPA) that confirms each terminal is fully seated before the harness leaves the bench.
Cap and TPA — Assembly Safeguards That Save Rework
Two features on this housing reduce the chance of a bad crimp making it into the field. The cap (cover) protects the contact cavities from debris during handling and shipping — caps stay on till you mate. The terminal position lock (TPA) is a secondary retainer that slides into the housing after the contacts are inserted; if a terminal isn't fully seated, the TPA won't lock, flagging the problem before the harness is mated. On a 20-position, 5-row connector, that kind of built-in inspection saves the cost of a continuity test later.
Panel-Mount Locking Ramp — Vibration-Resistant Mating
Combined with the panel-mount flange, this housing is designed for a fixed installation where the cable side gets plugged and unplugged during service. The 5-row, 20-position layout packs a lot of circuits into a single panel cutout, so the locking ramp takes the strain off the individual contacts during unmating.
The crimp termination style means the contacts are field-installable with the right tooling, saving a trailer trip back to the shop for a pre-terminated lead.
