Product Details
SensaGuard 440N Cylindrical Non-Contact Switch
The SensaGuard Non-Contact Switch is PLe, SIL 3 and Cat 4 rated and is intended for use with sliding, hinge or lift-off machine guard doors.

Combined with a large sensing range for optimum operation and tolerance to misalignment, these non-contact switches are a cost-effective solution to a wide range of industrial safety applications.
No dedicated controller required for its RFID coding security
Switches can be connected in series with other devices (e.g. Light Curtains, E-stops, interlock switches)
PLe, SIL 3, Cat 4 rating maintained with multiple units connected in series
Can be connected to standard safety relays, SmartGuards and safety I/O blocks
They provide three different types of PNP output including one auxiliary PNP
Equipped with an LED to indicate the device status and any faults
