Schmersal Light Beam Sender, 75m Height Range, 1 Beam – SLB440 Series – SLB440-E-1-ST


Make your production and assembly areas safer with this light beam sender from Schmersal. It detects the difference between humans and objects, so it only stops machinery when there’s a risk to a person’s safety. This enhances the efficiency of your workflow, as there’s a lower risk of false safety stops. A fast response time of 7 to 22ms means processes are halted almost instantly to reduce the risk of accidental injury. As there’s no need for a physical barrier such as a guard door, your work area stays visible at all times for greater ease of monitoring.
