The shrouded single wall and friction lock provide basic polarization and retention against vibration, while the through-hole solder termination keeps assembly straightforward. Rated 600 VAC, with current capacity depending on the wire gauge used in the mating connector — the header itself is not the current-limiting element. ## Mating Half and Retention This header mates with MTA-156 receptacle housings that accept the matching crimp terminals. The friction lock engages with the receptacle latch to hold the pair together under moderate vibration. The tin-on-tin contact interface (mating and post finish) is cost-effective for moderate mating-cycle applications.","metaTitle":"1-644752-7 TE MTA-156 Header 17 Pos 3.96mm Friction Lock","metaDescription":"1-644752-7 TE Connectivity AMP Connectors MTA-156 vertical header, 17 positions, 0.156\" pitch, friction lock, 600 VAC, UL94 V-0.
