Monitoring Door Closure with AS-Interface Safety Switches [Movie]

The doors and safety cages in active machinery areas have to be monitored to ensure worker safety. For this application Pepperl+Fuchs offers accessories to our AS-Interface safety switches. Accessories include a door handle and installation plate, which makes mounting simple and economical.

In this example, the door closure, the guard-locking function and the enabling switch on the protected work-cell is monitored by AS-Interface.

The latching function signals to the control system whether the door is open or closed and protects personnel from direct contact with the machine. The guard locking function ensures that the protective doors cannot be opened during operation. Enabling switches ensure safe working conditions in the machine area during setup and maintenance work.
