Motion, presence and safety sensor for automatic industrial doors


BEA’s LZR-Widescan is a LASER-based, time-of- flight sensor used for motion, safety and presence detection in a variety of industrial door applications. This all-in-one solution offers the benefits of activation and safety, while reducing installation time.

This NEMA 4 rated sensor creates a volumetric detection area by generating seven angled LASER curtains. It has the ability to detect objects based on direction, speed, object size and height.

The LZR-Widescan detection field operates independent of ground conditions, allowing for superior functionality in harsh environments.


Alternative Solution

Ideal for replacing costly / labor-intensive induction loop and pull-cord solutions


Promotes energy savings by reducing false detections / unnecessary door cycling, helping to regulate HVAC

Virtual Pull-Cord

Virtual pull-cord function can differentiate between pedestrian and vehicle traffic and can provide pulse-on-stop activation

Visible Spots

Two visible LASER alignment spots ensure accurate pattern placement
