A cast aluminum limit switch built for foundries, cutting lines and crane runways. One lever stroke drives two independent circuits, so a single switch feeds the control loop and the safety loop at the same time.
WHAT MAKES THE WL SERIES
The outer shell is cast aluminum, poured as a single rigid body. It absorbs the knocks, dust and vibration that foundries and crane runways deal out every shift.
The housing structure blocks oil, water and external pressure at the same time, and the whole unit holds an IP66 rating. Cutting-fluid spray and washdown stay outside the enclosure.
Roller levers, sealed plungers, spring rods and fork levers all mount on the same cast body. One series covers vertical strikers, sweeping cams and multi-direction triggers.
The built-in contact stand works on paired springs rather than one. Contact pressure stays even across a long mechanical life, and one actuator stroke switches both circuits together.
An indicating plate on the body marks the set operating position. Maintenance staff confirm the setting at a glance, so routine checks and resets take minutes.
Every model ships with an M20×1.5 cable gland. Wiring lands on a standard thread size that installers already carry in the van.
WHERE WL FITS
One lever stroke reports travel limit and trolley position to two separate circuits at once. The cast shell tolerates outdoor gantries and constant vibration.
Final limit protection at the hoistway ends. The double-circuit block lets one switch serve the control panel and the safety chain together.
