2-178138-2

The TE Connectivity 2-178138-2 is a 3-position, single-row, shrouded header designed for board-to-board or cable connections. It features a 5.08mm pitch and right-angle through-hole mounting, making it suitable for compact PCB layouts where space is limited. The header is shrouded on all four walls, providing protection for the male pins and ensuring reliable mating with compatible receptacles. The detent lock mechanism secures the connection, preventing accidental disconnection under vibration. The contacts are made of copper alloy with a tin finish, offering good conductivity and corrosion resistance. The insulation is black thermoplastic, glass-filled polyester rated UL94 V-0 for flammability. The board lock feature secures the header to the PCB during soldering. With a voltage rating of 600V and an operating temperature range of -55°C to 105°C, this header is suitable for industrial and commercial applications requiring robust connections. The contact length mating is 3.81mm, and the insulation height is 9.35mm. The header is RoHS compliant (unverified) and has an MSL of 1 unlimited.
