The Flexi Loop safety controller node can cascade up to 32 safety switches and OSSD safety sensors onto one loop — independent of the manufacturer. The Loop uses a single cable with an M12 plug to connect e-stops, sensors, switches, lamps, pushbuttons, and interlocks. This modular safety concept integrates all common fieldbuses, including Ethernet/IP, CANopen, DeviceNet, and Profinet IO. Diagnostic data about each of the sensors connected to the loop can be shared via these gateways. The Flexi Loop monitors each sensor individually and targets safety applications in the packaging, commercial goods, and electronics and solar industries that require several doors, e-stops, and electro-sensitive protective devices.
