A-B 440N-S32017 Guardmaster Safety Sensor

Product Description

Allen-Bradley 440N-S32017 is a Guardmaster Sipha Series Non-Contact Safety Switch / Safety Sensor manufactured by Rockwell Automation. It is designed for machine guard door monitoring, using a non-contact magnetic sensing method to detect whether safety doors, covers, or protective guards are closed correctly.

The device includes a standard actuator, red ABS plastic housing, and 10 m cable, providing a reliable safety interlock solution for industrial machinery protection.
