It's a tactile snap during assembly — you feel it seat — but it's not a secondary lock (TPA). For moderate vibration environments like a control cabinet or consumer appliance, it holds the pair mated without needing a separate latch mechanism. ## Shrouded 4-Wall — Pin Protection and Mis-Mate Prevention The 4-wall shroud surrounds the male pins on all sides. It is still in regular production with no announced end-of-life or last-time-buy window.","metaTitle":"2-644861-2 TE Connectivity MTA-100 Header 2 Pos 2.54mm","metaDescription":"2-644861-2 TE Connectivity AMP Connectors MTA-100 shrouded header, 2 positions, 0.100\" (2.54 mm) pitch, friction lock, tin contacts.
