It mates with any MTA-156 receptacle housing that uses the same friction-lock keying. ## Friction lock and vibration duty The shrouded one-wall design includes a friction lock — not a ramp latch. That means the mating receptacle clicks into place with a push and stays put under moderate vibration, but it won't resist a hard yank on the wire. For high-shock environments, the MTA-156 series also offers a positive-lock version; this part is the lighter-hold option.","metaTitle":"644753-4 TE MTA-156 Header, 4 Pos, 3.96mm, Friction Lock","metaDescription":"644753-4 TE Connectivity AMP Connectors MTA-156 header, 4 positions, 3.96mm pitch, shrouded, friction lock, through-hole, tin contacts.
