Limit Switch

Limit switches sense position by direct physical contact, so a machine knows a part has arrived rather than inferring it, which is why they still hold up where dust, coolant or vibration defeats a non-contact sensor. Conveyor and door builds need them when travel has to stop at a hard end point, when an actuator has been bent or worn past reliable contact, or when a crane or gate needs its limits set mechanically for safety.

 

As an authorized electrical distributor for multiple manufacturers, we stock limit switches from ABB and more across competing lines, with plunger, roller lever and rod actuators, so you can match the actuator the machine already uses, compare bodies and contact ratings across brands, and replace a switch without resetting the trip point.
