The SE2L safety laser scanner offers master/slave functionality and dual protection zones. Master/slave functionality allows one SE2L scanner to act as master and communicate with up to three other scanners. The safety controller needs to communicate only with the master, reducing the required number of input and communication channels on the controller. Dual zone protection allows one SE2L scanner to scan two adjacent zones simultaneously and independently, performing the work of two scanners for the cost of one. The scanner provides a standard 270° arc of protection at a distance up to 20 m.
