SI-RF Series safety switches utilize RFID technology to monitor doors, gates, and other movable mechanical safeguards that separate personnel and equipment from a hazard. They will send a signal to the machine control system to prevent or stop hazardous situations when the guard is not in the proper position.

• In-Series Diagnostics (ISD) provides detailed status and performance data from each sensor in a cascade chain which can be accessed with an HMI or similar device
• Single and cascade models available to protect one or multiple entry points
• On-sensor LED indicator provides at-a-glance status information
• Cascade up to 32 sensors in a series using a standard 4-wire cable with M12 connectors, T-adapters, and an end plug
• Tamper resistance to meet the needs of any application with unique, high, and low code models
• Achieves Cat 4, PL e, or SIL CL 3 safety ratings alone or in a cascade chain
• Rugged, IP69 construction withstands exposure to high-pressure, high-temperature washdown
• High tolerance (10 mm) to misalignment enables reliable performance in challenging industrial environments where machine vibration and impact are possible
