The red closed-end housing and locking ramp make it a one-way mate with the matching header; the ramp holds against vibration in an industrial cabinet or appliance. Tin-on-tin interfaces work well for a permanent or infrequently mated harness — the plating wipes clean on insertion and the locking ramp keeps the pair mated. What it does not do is survive hundreds of mate-unmate cycles; if this connector sees frequent field disconnects, a gold-plated sibling would be the better call. For a one-time build inside an enclosure, the tin finish is exactly what keeps the BOM cost down.","metaTitle":"TE MTA-156 4-640428-7, 17 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 4-640428-7 receptacle, 17 positions, 0.156\" pitch, IDC termination for 22 AWG wire, tin contacts, locking ramp.
