Product description

The Allen Bradley 440T-MSRUE11AA is a Guard Shield safety switch designed to enhance machine safety by providing a reliable interlocking mechanism for guards. This model features a standard tongue actuator, a common and effective solution for monitoring the position of access doors or guards. When the guard is opened, the tongue is withdrawn from the switch, triggering the internal contacts to safely shut down hazardous machine functions.

This safety switch is widely implemented across various industries, including manufacturing, automotive, food and beverage, and material handling, wherever machine guarding is critical. Its robust construction and IP67 rating ensure it can withstand challenging industrial environments, including those with dust and moisture.
