Safety system goes wireless
The new ESALAN Wireless safety system is an innovative addition to Schmersal's range of switchgear and systems designed to protect man and machine. Instead of traditional cables, the wireless safety system uses radio waves via a handheld controller to signal safety-critical devices. This makes it ideal for applications in factory environments.
The system's signal, which can be used for safety-stop controls, 3-phase enabling switches and other devices, meets the requirements of control category 4 to EN 954-1.
Up to fourteen wireless safety systems can be integrated into a typical factory and operated in direct proximity. Each handheld controller has a free-field range of up to 250 metres and an operating life of 50 hours.
Advantages include reduced machine downtime caused by damaged cables, improved productivity by allowing operators more freedom of movement, cost savings by replacing of discretely wired decentralised operating stations and the replacement of cables, slip rings, and other components that are subject to wear and tear.
