M12 D-Coded Panel Receptacle, 3-Pin, Solder Cup
It mounts in a panel cutout via a bulkhead nut and seals to IP67 when mated, keeping washdown water and dust out of the junction. The solder cup termination lets you attach the cable directly to the contacts without a crimp tool, which is handy for field repairs or short-run harness builds.
D-Code Keying and M12 Compatibility
The D-coded orientation is the defining feature here — it physically prevents mating with standard A-coded or B-coded M12 connectors, which is intentional for Profinet and Ethernet/IP applications where signal integrity and pin assignment must be guaranteed. Compare this to the A-coded T4130012031-000, which shares the same 3-position layout, 4 A rating, and gold-plated contacts but uses a different keyway. If your network calls for D-code, the A-code part will not mate, so the T4130512031-000 is the correct pick.
Panel Mount and Environmental Sealing
This receptacle uses a threaded coupling ring and a bulkhead nut to clamp into the panel, creating a vibration-resistant joint that holds up in machinery with constant motion. The IP67 rating means the mated pair withstands temporary immersion — think washdown stations, outdoor conveyor lines, or food processing floors where a hose-down is part of the cycle.
Current and Voltage Ratings for the Duty
The 4 A limit is per-pin, so a 3-position connector can carry up to 12 A total if the circuit load is distributed, but derate above 85 °C per the standard curve.
