Pepperl+Fuchs has introduced new AS-interface magnetic door safety switches. The CAT4 magnetic switches feature a coded magnet system with a fixed cable and an industry-standard M12 connector, enabling AS-interface users to safeguard small doors and coverings with a compact solution that quickly and easily mounts in any position.

According to Helge Hornis, manager for Intelligent Systems at P+F, using one a flat-to-round cable splitters allows network connection of the CAT4 switches in about 30 seconds.

With a 36 x 13 x 26.2mm footprint, model VAA-2E-IER2-S-1M-V1 is the most compact of the two available switches. With a moderately longer 87.5 x 13 x 25mm housing, model VAA-2E1A-IER1-S-1M-V1 features LED status indicators that provide users with easy-to-read visual diagnostics.

Fully-encapsulated electronics provide IP67/IP69K protection for an extended lifecycle (108 switching cycles). Operating temperatures ranged from -20°C to 60°C (-4°F to 140°F). As with all AS-Interface solutions, power and communication is supplied directly through the AS-Interface network.
