2. Access Control for Robotic Workcells in Limited Spaces

This light curtain is an excellent solution for defining and monitoring safe access zones around robotic workcells, especially where physical space is restricted. Its 13.2mm depth and 320mm protective height allow for minimal footprint integration, while the 20mm beam pitch ensures effective detection of personnel entering the safeguarded area.

Problem Solved

Ensures operator safety by detecting unauthorized entry into a robotic workcell, particularly in constrained layouts, and initiating a safe stop of the robot.
