Measuring light curtains are designed for dimensional measurement and object profiling, while safety light curtains are designed to protect personnel by stopping hazardous machinery when a person enters a dangerous area. They serve fundamentally different purposes. Key Differences FeatureMeasuring Light CurtainSafety Light Curtain Primary PurposeDimension measurement, position detection,...

Measuring light curtains are primarily classified by beam spacing (resolution), detection distance, and output type. The beam spacing determines the smallest object size the system can detect — the smaller the spacing, the higher the precision.

A measuring light curtain is an array of parallel infrared light beams emitted from a transmitter to a receiver. When an object enters the beam field, the system instantly detects which beams are blocked and calculates the object's size, position, and profile with high precision. How It Works The system operates on a through-beam photoelectric principle. The emitter contains multiple inf...
