The friction lock mates with the corresponding MTA-100 receptacle housing, providing positive retention against vibration without requiring a secondary latch. ## Current rating and termination Current rating is listed as varies by wire gauge — in the MTA-100 system, the per-contact limit depends on the crimp terminal and the wire size used in the mating receptacle. The tin-on-tin contact interface is rated for moderate mating cycles — suitable for field-service connections cycled a few times per year, not daily hot-plug duty.","metaTitle":"2-644486-9 TE Connectivity MTA-100 Header 9 Pos 2.54mm","metaDescription":"2-644486-9 TE Connectivity AMP Connectors MTA-100 shrouded header, 9 circuits, 0.100\" pitch, friction lock, tin plating.
