This heavy-duty mechanical limit switch delivers precise position detection and safety cutoff for automated machinery, built with die-cast alloy housing and IP65 dustproof & splash-proof sealing to withstand workshop dust, coolant splashes and slight vibration. Equipped with silver alloy SPDT 1NO+1NC snap-action contacts, it triggers instantly with zero delay, supporting AC 380V/DC 220V and rated 5A load capacity for stable circuit control. Multiple interchangeable actuators including roller lever, plunger and flexible spring rod fit diverse installation demands. Reinforced internal spring structure ensures fast automatic reset, with mechanical service life exceeding 10 million cycles for long-term continuous operation. Standard fixed mounting holes and screw-type terminals simplify wiring and assembly. CE and RoHS certified, it widely serves conveyors, lab mixers, vibratory sieves, packaging machines and lifting equipment, acting as a critical safety component to prevent overtravel collision and protect production devices reliably.
