Limit Switch: General-Purpose Device for Motion Position and Stroke Control

Limit Switch: General-Purpose Device for Motion Position and Stroke Control

The limit switch is a general term for switches used to restrict object motion positions or strokes, including travel limit switches, crane limit switches, micro limit switches, etc. It detects mechanical motion through contact or non-contact methods, triggering circuit changes at preset positions to control equipment operation or stop motion. Widely used in industrial automation, transportation, and construction machinery, this versatile switch is a fundamental component for ensuring safe and regulated motion in mechanical systems.

Advantages

Universal Motion Control Solution

Covers diverse applications (stroke, position, limit) with a single product category, simplifying procurement and inventory management.

Multiple Technology Options

Offers mechanical, optical, and magnetic types, adapting to contact or non-contact detection needs in different industries.

High Reliability in Critical Applications

Widely used in elevators, cranes, and aerospace equipment, with fail-safe designs meeting ISO 13849 performance level d.

Related products

To enhance the safe operation of lifts (elevators), a limit switch is added that detects the position of the car and the status of the door. Like other limit switches, it has two contacts forming a redundant system, thus complying with CEN standards, EN 81-1/2, and incorporating fail-safety measures for over-travel condition and misleveling the car. The slots for the guide rail brackets are equipped with a roller or plunger actuator that defines the stops at target floors for each level with an accuracy of 卤5mm. Shielding from electro-magnetic interferences and fireproof casing enables it to be used in critical infrastructure and high-rise buildings.

Frequently Asked Questions

What makes limit switches a universal safety solution?

Limit switches cover diverse applications (stroke, position, limit) with a single product category, simplifying procurement and inventory management. Their versatility across industries—from elevators to aerospace—makes them a fundamental safety component.
Limit switches offer multiple technology options, including mechanical, optical, and magnetic types, adapting to contact or non-contact detection needs. This allows selection based on environmental factors, precision requirements, or application complexity.

Kevin Wilson
Essential Limit Switch for Safe Motion Control

The limit switch is a fundamental component for controlling object motion and ensuring safety. It effectively limits travel and prevents overrun in our machinery. Easy to install and adjust, it offers reliable performance at a reasonable price. A must-have for any system requiring motion limitation.

Tom Li
Cost-Effective Safety for Small Businesses

For our small woodshop, these limit switches replaced expensive custom sensors at a fraction of the cost. The mechanical type works perfectly for our table saw's travel limits, and the adjustable screws let us fine-tune as we upgrade our equipment. Simple to install, reliable in daily use—ideal for businesses on a budget.
