Telemecanique Limit Switches
Telemecanique limit switches are electromechanical position sensors commonly used for object detection or as end-of-travel stops in industrial equipment. These rugged, high-precision switches are ideal for a variety of automation and machinery applications. With a variety of actuator styles including plungers, roller levers and adjustable arms, these limit switches provide repeatable, reliable detection of machine movement, presence/absence and end-of-travel limits.
Telemecanique limit switches feature tough housings and robust mechanical designs to withstand impact, cycling and physical abuse. Many models offer IP67 ingress protection for harsh industrial environments. Electromechanical operation provides positive, tactile switching feedback with each actuation, ensuring switch state is clearly communicated to operators or machine control systems. Telemecanique offers a wide selection of actuator types, contact arrangements (snap-action/momentary or stay-put/latching) and wiring configurations to suit various actuation forces, interface needs and mounting locations.
Designed for repeatability and reliability, many Telemecanique limit switches are used as interlocks or safety devices in safety circuits to monitor positions and limit travel. Common for machine tools, robots, conveyors, packaging, hoists and OEM equipment due to their compact, enforceable switching. Their predictable mechanical behavior and compatibility with standard industrial control systems make them easy to integrate into new or existing installations. Because of their combination of precision, toughness, and configurability, Telemecanique limit switches remain a trusted choice for engineers designing motion-dependent safety and control systems.

Limit Switch Basics
What are limit switches?
Limit switches are electromechanical switches that operate based on the movement or presence of an object. They are designed to detect the presence of an object using an actuator connected to a series of contacts to detect the presence and proximity or absence of a material or object. When the switch's actuator is moved by an object it will change the state of an electronic contact set. This movement signals that some preset limit has been reached. There are many different ways a switch can be actuated depending on the type of switch that is being used. Some use a roller and lever, some use a button or plunger, while others might use a rotating arm and rod attached to the main body of a switch. The type of switch that is used will largely be dictated by the specific application.
Where are limit switches used?
Limit switches can be used to tally or count items, so that when a limit is reached, the switch will open or close. This open and closing action can be counted by a controller allowing the action to be totalized. Limit switches can be used as safety interlocks to prevent machine parts from moving any further when specific point is reached. Limit switches are also commonly used in larger control systems. For example, when a certain limit is reached, the actuator can deactivate or activate a device to prevent it from malfunctioning.
