Siemens 3SE03-DT3 Limit Switch Operating Head

Siemens 3SE03-DT3 Limit Switch Operating Head is the roller-top plunger head for the 3SE03 limit switch family, delivering momentary actuation when engaged by a roller-type actuator. This top-plunger operating head mates with Siemens 3SE03 limit switches and uses a roller top plunger with about 0.28 inches of travel and roughly 5 degrees of pretravel to operate the contacts, ensuring reliable signaling for light to moderate mechanical inputs. The head is die-cast zinc and rated for IP67 ingress protection, designed to withstand temperatures from -10 to 121 degrees Celsius, and it requires about 4 in-lb of operating torque to actuate. Its top-location actuator and rugged construction suit harsh industrial environments, including conveyors, safety interlocks, and machine-control circuits, when used with the corresponding 3SE03 switch body, and it is compatible with a wide range of enclosures (NEMA 1, 3, 3S, 4, 4X, 6, 6P, 11, 13).
