Which light curtain suits you best?

By dividing the light curtains into two different categories: detection and measurement, you can find the right product for your application.  Scroll down to read the categories.

Detection light curtains 

The purpose of a detecting light curtain is to monitor a defined area with the help of invisible, infrared light beams. The light curtain system consists of a transmitter and receiver. If any beam occurs between transmitter or receiver, it will be registered by the internal control unit and signalled via the push-pull output. 

With DUOmetric detecting light curtains, the control unit is integrated into the transmitter and receiver profiles making our light curtains compact, slim and powerful!

Duometric measurement light curtains

Door and doll / lock monitoring 

Our light curtains for doors can be built up to a monitoring height of 6 metres offering safety and comfort.

System for access sports

Detecting light curtains are also used to control the flow of people. They are built into automated boarding gates or used for direction detection in security door systems.

Measurement light curtains

Measurement light curtains work within a defined surveillance area with several invisible infrared light beams. The light curtains consist of a transmitter and a receiver in thin anodized aluminium profile and an external control unit. 

These light curtains work according to the principle of evaluating each individual beam detected by the external control unit. As a result, complex measurement tasks can be carried out and the control unit activates the corresponding outputs and digital data transmission.

Our products can provide an accurate measurement of an object's height, length or width.
