Wlca2-2 IP67 Aluminum Stainless Steel Roller Lever Limit Switch for Elevator Winch

Product Description

WLCA2-2 heavy-duty two-circuit limit switch with IP67 waterproof & dustproof rating, cast aluminum housing and stainless steel roller lever. Robust snap-action contact structure, widely used for elevator, aluminum winch and automation machine stroke safety control

WLCA2-2 is a double-circuit heavy-duty travel limit switch, equivalent to WL series industrial limit switch. It adopts sturdy cast aluminum alloy housing, equipped with anti-corrosion stainless steel roller lever actuator. IP67 sealed construction provides full dust protection and resistance against water splash for harsh workshop and outdoor working environments. The double-circuit contact design enables independent signal output for safety interlock monitoring. Premium silver contacts guarantee stable conductivity and long service life. It supports large overtravel angle with high mechanical strength, resisting frequent impact and abrasion. Screw terminals bring convenient and firm wiring. Commonly applied on elevators, aluminum winches, lifting hoists, conveyors and packaging machinery for position detection, stroke limitation and safety cut-off protection. CE & RoHS certified for global industrial markets.
