3431-1302

The 3M 3431-1302 is a rectangular connector header with male pins, part of the 3M family of interconnect solutions. It features 34 positions arranged in 2 rows with a 2.54mm pitch, making it suitable for dense board-to-board or cable-to-board applications. The header is mounted through hole with a right angle orientation, allowing for perpendicular connections to the PCB.

Key electrical specifications include a current rating of 1A per contact and an operating temperature range of -55°C to 105°C. The contacts are made of copper alloy with a Tin-Lead finish, and the insulation material is a glass-filled PCT/polyester compound rated UL94 V-0. The housing is black and includes a keying slot and mounting flange for secure alignment.

The connector features a shrouded design with 3 walls and a long latch lock/eject hook fastening system, ensuring reliable mating and easy disconnection. The contact length is 2.84mm, and the row spacing matches the pitch at 2.54mm. This header is intended for use in applications requiring robust mechanical retention and electrical performance in moderate temperature environments.
