The right-angle orientation lets the mated cable run parallel to the board, saving vertical space in cramped enclosures. The friction lock engages with the matching MTA-100 receptacle housing, giving a positive hold against vibration without needing a separate latch mechanism. Tin-plated contacts on both mating and post sides keep the cost down for moderate-cycle applications. ## Shrouded Housing and Friction Lock — Vibration-Resistant Mating The four-wall shroud protects the male pins during handling and guides the receptacle into alignment before the pins engage — reduces the chance of bent pins during blind mating. The friction lock then holds the pair together; you'll feel it click when the ramp snaps over the receptacle's locking tab. Rated for 250VAC and a temperature range of -55°C to 105°C, this header suits general-purpose indoor equipment where the environment stays dry and the current stays within the wire-gauge derating curve. The UL94 V-0 polyester housing meets the flame rating required for most commercial electronics enclosures.","metaTitle":"3-644803-0 TE MTA-100 Header, 10 Pos, 2.54mm, Right Angle","metaDescription":"3-644803-0 TE MTA-100 shrouded header, 10 positions, 0.100\" pitch, right-angle through-hole, friction lock.
