The IDEC SE2L safety laser scanner is the smallest in the world, while outperforming most of the competition. Features include a 270-degree sensing angle, a 5m safety protection zone, a 20m warning zone and customizable protection patterns. Master/slave functionality allows one SE2L scanner to act as master and communicate with up to three other scanners. The safety controller only needs to communicate with the master, reducing the required number of input and communication channels on the controller.
