The white closed-end housing keeps the wire entry side sealed off, which is handy when you're daisy-chaining connectors along a harness and don't want an open end collecting dust. ## Key Specs for the Harness Builder This plug accepts 24 AWG wire only — the IDC slot width is sized for that gauge, so don't try to stuff 26 AWG in there; the insulation won't displace cleanly and you'll get an intermittent connection. The free-hanging right-angle mount means the wire exits perpendicular to the mating face, useful when you're routing a harness along a panel edge and need the connector to sit flat against the board. Being a male pin plug, this mates with any MTA-156 female socket receptacle — look for the matching 4-position receptacle housing with female blade contacts. The IDC termination is straightforward: lay the unstripped wire across the slot, press the cover down with a hand press or arbor press, and the slot edges cut through the insulation to make contact with the conductor. No wire stripping, no crimp die changeover. The closed-end feature means the wire entry is blocked on one side, so you only load wire from the open end — keeps the assembly oriented consistently.","metaTitle":"TE 3-641438-4 MTA-156 Plug, 4 Pos IDC, 0.156\" Pitch","metaDescription":"TE 3-641438-4 MTA-156 4-position IDC plug, 0.156\" (3.96mm) pitch, 24 AWG, tin-plated male pins.
