Product Description
WLD3 heavy-duty IP67 travel limit switch with stainless steel top ball plunger and solid cast aluminum shell. Double-circuit 1NO+1NC contacts, self-reset snap action, dustproof & waterproof, widely used for automation machinery stroke limit and safety position detection
WLD3 is a top ball plunger type heavy-duty industrial limit switch with IP67 protection grade. It adopts robust cast aluminum alloy housing for high mechanical strength, shock resistance and oil resistance. The actuator is made of stainless steel ball plunger for wear resistance and long service life. Built-in double-circuit silver contacts deliver stable signal transmission and low contact resistance. Snap-action self-reset mechanism ensures fast response and excellent repeat positioning accuracy. The sealed structure prevents dust and water splash, suitable for harsh humid and dusty workshop environments. Screw terminals support convenient wiring and installation. Commonly applied in automated machines, lifting hoists, conveyors, packaging equipment for stroke limitation and safety interlock control. It can be used as compatible replacement for Omro WLD3 series limit switches. CE & RoHS certified for global industrial markets.
