The friction lock provides a positive retention with the mating housing without needing a separate latch or screw, which simplifies field assembly and reduces the chance of accidental disconnection under vibration. ## Pitch, shroud, and lock — the fit details The 0.156\" pitch is the key board-layout dimension — it sets the hole spacing for the through-hole solder tails. The 0.125\" post length and 0.300\" mating pin length define the stack height when mated with a standard MTA-156 receptacle. The 4-wall shroud fully encloses the pins, which prevents bent contacts during blind mating and protects against accidental shorting. All 3 positions are loaded, so there are no empty cavities — the header is ready for a full 3-circuit harness. ## Current rating and plating — what the numbers mean for your circuit This thickness provides good corrosion resistance and supports moderate mating cycles typical of field-serviceable wire-to-board connections.","metaTitle":"2-647127-3 TE Connectivity MTA-156 Header 3 Pos 3.96mm","metaDescription":"TE Connectivity AMP Connectors 2-647127-3 MTA-156 shrouded header, 3 positions, 0.156\" pitch, friction lock, tin-plated contacts.
