The 3.96 mm pitch matches the standard MTA-156 receptacle spacing, and the friction lock keeps the mating housing seated under light vibration — common in industrial control panels and general-purpose equipment enclosures. ## Pitch, positions, and partial population At 3.96 mm pitch, this header occupies a standard 0.156-inch grid — the same footprint as other MTA-156 connectors. The 19-position housing accepts up to 19 contacts, but this variant ships with only 15 cavities loaded. That partial population saves cost when the harness needs exactly 15 circuits, without requiring a custom-moulded housing. The 0.400-inch (10.16 mm) mating pin length provides ample engagement depth for the receptacle contact, ensuring reliable connection even with housing tolerances stacked. ## Rated for 600 VAC, UL94 V-0 housing The header is rated 600 VAC — sufficient for line-voltage industrial equipment up to 480 VAC phase-to-phase.","metaTitle":"644961-1 TE MTA-156 Header, 19 Pos Right Angle, 3.96mm Pitch","metaDescription":"TE MTA-156 header, 19 positions (15 loaded), right-angle through-hole, 3.96mm pitch, friction lock, 600VAC, UL94 V-0.
