The Allen-Bradley 440N-Z SensaGuard non-contact switch with a magnetic integrated latch combines a non-contact interlock switch and door latch into one integrated solution. It replaces separately mounting an interlock switch and door catch in lightweight guard doors.
The switch features the latest RFID technology for coding, inductive technology for sensing and output switching signal device (OSSD) safety outputs. It is available with a uniquely coded sensor and actuator to help protect against operators or maintenance personnel defeating the switch, helping to enhance safety. In addition, an LED on the switch provides diagnostic status.
