Sensor-Ring Circular Sensing Edge
A pressure sensitive safety edge that provides an exact fit
for circular geometries and is available as a full or partial circle
The Sensor-Ring Circular Sensing Edge from Tapeswitch offers a unique and effective solution for applications requiring a large curved or circular sensing element. It replaces multi-piece, multi-switch solutions with a single, curved, pressure sensitive sensing edge that provides contact closure at any point. The hollow-ring design permits pass-through of wires, components, or personnel.

The Sensor-Ring Pressure Sensitive Safety Edge is constructed with a Santoprene TPE housing which is resistant to water, oil, hydraulic fluids, and coolants. It is available in partial or full circle models with diameters up to 5 ft. Mounting can be customized to suit the application. All Sensor-Ring Sensing Edges are supplied with 4-lead fail-safe wiring and are compatible with Tapeswitch Safety Controllers.
