What This M12 Receptacle Is — and the Common Ordering Trap It Avoids
The T4142412041-000 is a 4-position M12 receptacle with male pins — the less common gender in the M12 world, where receptacles typically house female sockets. This is a male-pin panel-mount, meaning the pins protrude from the face and mate with a female-socket cordset. The B-coded orientation follows the IEC 61076-2-101 standard for sensor/actuator networks, typically Profibus or DeviceNet applications. The threaded fastening and IP67 sealing make it suited for industrial cabinet pass-throughs, washdown zones, and outdoor junction boxes where dust and moisture are present. Gold-plated mating contacts with 3.00µin thickness handle the repeated mating cycles typical of field-service connections without fretting corrosion.
Ratings That Define the Fit
The 4-position count matches the standard M12-4 shell size, which is the most common pin count for this form factor. The operating temperature range of -40°C to 85°C covers industrial cabinet and outdoor enclosure conditions, but note the upper limit is 85°C, not the 105°C or 125°C some M12 variants carry — if your application sees sustained heat near that ceiling, derate the current per the manufacturer's curve.
Mounting and Termination — What the Panel Build Needs
The shell is nickel-plated copper alloy, which gives good corrosion resistance in industrial atmospheres but is unshielded — if your cable run passes through high-EMI areas, you will need a shielded cordset and a conductive backshell, not this part alone. Termination is solder cup, so the cable assembly shop needs to hand-solder each pin; no crimp option is offered on this variant. The silver colour is the natural nickel finish, not a paint or coating.
