The unshrouded design means the male pins are exposed — no shroud to guide or polarize the mating half, so alignment relies on the connector body keying. ## Tin-Plated Contacts for Low-Cycle Interconnects The 150 µin thickness provides a robust wear layer for the expected mating cycle life of this connector class. ## Through-Hole Mount with Kinked Pins The header terminates via kinked pins soldered into plated through-holes.","metaTitle":"3-644695-2 TE Connectivity MTA-100 Header, 2 Pos, 2.54 mm","metaDescription":"3-644695-2 TE Connectivity AMP Connectors MTA-100 unshrouded header, 2 positions, 0.100\" pitch, through-hole, tin plating, 250 VAC.
