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.


Easy setup

Precise activation zones allows for installers to walk the desired detection area


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 alignment spots indicating safety field location ensuring setup
