The L77HDC62SD1CH4F is a high-density D-Sub connector featuring 62 contacts in a right-angle PCB-mount configuration with a tin-plated steel shell and selective gold-plated copper alloy contacts. This connector is designed to accommodate greater signal density compared to conventional D-Sub connectors through decreased contact spacing, while maintaining robust electrical performance with a 3A current rating and 300V AC/rms voltage rating at 50Hz. The connector exhibits a mating force of 13.48 kg (29.78 lb) maximum and unmating force of 1.76 kg (3.88 lb) minimum, with an insulation resistance of 5000 MO and contact resistance of 10 mO maximum. The glass-filled thermoplastic body (UL 94V-0) combined with brass nickel-plated rear insert and screwlock provides economical, reliable performance for industrial, telecom, and standard I/O connection applications requiring high-density signal routing.
