Non-Contact Switches With Sensaguard

Protection of personnel and equipment is a main concern on the plant floor. At the same time, safety systems should be designed to offer flexibility and promote productivity. The new Allen-Bradley SensaGuard family of RFID-coded, non-contact switches from Rockwell Automation meets all these design needs ? a marketplace innovation. These switches are Category 4/SIL 3 rated as per EN954-1, T?V functional safety approved to IEC61508. Unlike lower rated switches, the SensaGuard will shut down a machine if a failure occurs before there is a demand on the safety device ? which improves machine operator safety. SensaGuard is especially suited for machines where multiple access doors must be monitored up to a Safety Category 4/SIL 3. In addition, it does not need a dedicated controller, allowing system designers to use one relay to support the entire safety system, including light curtains, e-stops and non-contact switches. Switches can be connected to a standard safety relay, such as the MSR126, MSR127, MSR200/300 Family, SmartGuard and safety I/O blocks. This application feature helps reduce machine wiring costs. SensaGuard also contains built-in diagnostic capabilities, with green and red LED lights respectively indicating the machine running safely and a case of failure, alerting operators directly to the problem switch. Featuring the latest generation of RFID technology for coding and inductive technology for sensing, SensaGuard offers a large sensing range and tolerance to misalignment. It also features a variety of package styles, including tubular, and can be mounted with a standard bracket, which offers designers convenience and flexibility. Applications are in all manufacturing markets, including those that utilise high pressure wash downs, such as automotive, food, beverage, packaging and material handling. SensaGuard is IP69K environmental-rated, and also offers short-circuit and overvoltage protection.
