The 1437025-4 is a 50-position female socket transition connector assembly from the +622 series. It is designed for the termination of 26 or 28 AWG stranded or solid PVC insulated flat ribbon cable. The connector features beryllium copper contacts with gold plating on the mating area and a bright tin-lead finish on the termination end, all over a nickel underplate. Housed in a blue, UL94V-0 rated thermoplastic, it operates across a temperature range of -55°C to 125°C. This model includes a strain relief but does not have a center polarizer, making it suitable for a variety of board-to-cable interconnect applications.
