Features

High detection accuracy

Equipped with resolutions of 2.5mm, 5mm, 10mm, 20mm, 40mm, and 80mm, meeting the requirements of various application scenarios. It can precisely detect opaque objects with a diameter greater than 2.5mm, with a response time as fast as 5ms.

Blanking Function

Equipped with a floating blanking function: the ability to disable a portion of the detection area of the safety light curtain. Commonly used in situations where detection of specified-width moving objects in a particular region is not desired.

Digital Tube

Real-time display of the number of blocked beams on the safety light curtain. For example, it shows '00' during normal operation and displays the quantity when beams are blocked, providing accurate feedback on the condition within the monitoring area.
