The shrouded - 1 wall protects the male square pins from bending during mating, and the friction lock retains the mating housing under vibration or cable strain. All 9 positions are loaded with tin-plated copper alloy pins. ## Termination and mounting for through-hole assembly The board guide and keying slot assist alignment during automated or manual insertion.","metaTitle":"3-644615-9 TE Connectivity MTA-156 Header 9 Pos 3.96mm","metaDescription":"3-644615-9 TE Connectivity AMP Connectors MTA-156 header, 9 positions, 3.96mm pitch, shrouded, friction lock, tin contacts, UL94 V-0.
