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. This non-contact system operates at the highest levels of safety, resists tampering and nuisance trips, and offers diagnostic capabilities that make it easy to resolve problems and minimize machine downtime.
SI-RF Series safety switches work in easy-to-deploy pairs consisting of an RFID coded actuator and an RFID safety sensor. Users can connect a single sensor or up to 32 cascaded sensors using a standard 4-wire cable with quick disconnect M12 connectors, T-adapters, and an end plug. A single cascade chain uses only two terminals on a safety controller, freeing space to connect other devices.
In-Series Diagnostics (ISD) provides users with status and performance data from each sensor in a cascade chain. The collected data is sent to an IO-Link gateway and can be accessed with an HMI or similar device. Users receive notification when an event has occurred as well as where in the series the event occurred. Events can include the opening or closing of a door, wrong actuator taught, misalignment, and a range of additional system health attributes.
Low code models are an easy-to implement and easy-to-manage option for applications with a relatively low risk of tampering. A low code SI-RF sensor will detect any SI-RF actuator without being taught.
High code models are very resistant to tampering. The sensor in this pair will work with one specific actuator at a time. An additional 11 actuators (for a total of 12) can be taught in succession and previously used actuators will no longer work.
Unique code models offer the highest level of tamper resistance. The sensor and actuator in this pair will only work with each other. The RFID code is completely unique to that actuator and no additional actuators can be taught to the sensor.
SI-RF Series safety switches achieve Category 4, PL e, or SIL CL 3 safety ratings alone or in a cascade chain. Outputs on each sensor in a cascaded series are continuously monitored to detect any faults, including short circuits. This design eliminates the possibility of fault masking at any point in the system.
Versatile and easy-to-use, SI-RF Series safety interlock switches safeguard doors, gates, hatches, and similar moveable mechanical guards.
