The 0.156\" (3.96mm) pitch leaves enough board space for routing wider traces and accommodates 18-22 AWG wire in the mating receptacle without crowding. This lock resists moderate vibration in industrial control panels and general-purpose equipment. The 0.425\" (10.80mm) insulation height above the board gives clearance for components underneath the header body on a densely populated board. ## Voltage and Temperature Rating for Industrial Use Rated 600VAC — this covers most single-phase and three-phase control circuits inside equipment without needing a higher-voltage connector. ROHS3 compliant. Bulk packaging — the header ships in standard tubes or trays, not tape-and-reel. ## Mating Housing Compatibility This header mates with the MTA-156 receptacle housing (TE part number 1-640456-4 or equivalent). The friction lock engages the ramp on the receptacle shroud — if the lock doesn't click, the housing isn't fully seated.","metaTitle":"1-640388-4 TE Connectivity AMP Connectors Header, 14 Pos","metaDescription":"1-640388-4 TE Connectivity MTA-156 header, 14 positions, 0.156\" pitch, tin-plated, friction lock, UL94 V-0.
