121583-0006 is an APD 4-way flange receptacle connector with pin gender, designed for reliable electrical connections in transportation applications. The connector features Code 3 green mechanical keying (RAL 6029) for positive identification and operates at 48 VDC with a maximum contact resistance of 5 mO. It is rated for 1000 VAC voltage proof (60 seconds) and maintains an insulator resistance of 10 MO minimum, with durability rated for 50 mating cycles. The connector operates across a temperature range of -40°C to 140°C and achieves IP 67 + IP 69k sealing protection per DIN EN 60529. The housing is constructed from PBT GF material with HNBR sealing (alternative FKM available), and it withstands static loads of 250 N axial and 150 N lateral when mated, making it suitable for demanding automotive and industrial environments requiring robust, sealed connections.
