Product Overview
The WLCA12-TH-N is built for position and end-of-travel detection where durable mechanical contact sensing is preferred. It is commonly used in conveyors, machine guards, and transfer equipment.
Heavy-Duty Mechanical Construction
The robust enclosure and actuator assembly are intended for repeated operation in industrial environments, including locations with vibration and contamination concerns.
Reliable Position Feedback
Mechanical actuation provides clear state transitions for PLC inputs and interlock circuits in motion systems and machine sequencing.
Flexible Use in Machine Designs
Limit switches in this class are applied for travel limits, door position confirmation, and mechanism state detection where optical methods are not ideal.
