Product details

Mounting and enclosure reality

The 3SE5312-0SE11 is a metal-housed safety limit switch with a separate actuator and tumbler design, mounted via screw fixing in any position. Three M20 x 1.5 cable entries give flexibility for conduit or gland routing in panel or machine-frame installations.

Locking force and contact rating

Rated locking force is 2 600 N per EN ISO 14119 — this is the force the spring-actuated lock resists before the guard can be opened. The slow-action contacts (not snap-action) are rated for a thermal current of 10 A, with switching capacities of 6 A at 120 V and 3 A at 240 V.

IP66/IP67 protection means the switch withstands hose-directed water and temporary immersion — suitable for washdown zones or outdoor machine guarding. Shock resistance is 30 g / 11 ms per IEC 60068-2-27, and vibration resistance is 0.35 mm / 5 g per IEC 60068-2-6.

Frequently asked questions

Does the 3SE5312-0SE11 include an actuator?

Yes — the product is designed with a separate actuator and tumbler (design of the product: with separate actuator and with tumbler). The actuator is a separate component that must be mounted on the guard; the switch body mounts on the fixed frame.
