5-2271101-1 is a 50-position D-shaped SCSI receptacle connector designed for cable-to-board applications. It features a 1.27 mm (0.05 in) centerline pitch, full metal shell construction with steel shell material, and thermoplastic housing. The connector utilizes copper alloy contacts with gold plating (0.3 µm thickness) on the mating area and nickel underplating, supporting a maximum contact current rating of 1 A. With an operating temperature range of -55°C to 105°C and UL 94V-0 flammability rating, this connector is suitable for panel mount and board mount configurations with retention leg PCB mounting. It is commonly used in SCSI interface applications requiring reliable high-density connections.
