SensaGuard RFID Non-Contact Safety Switches

April 8, 2009
Featuring the latest generation of RFID technology for coding and inductive technology for sensing, SensaGuard's large sensing range and tolerance to misalignment is a cost-effective solution ideally suited to a wide range of industrial safety applications. 

It also features a variety of package styles, including tubular, and can be mounted with a standard bracket, which offers designers convenience and flexibility.
SensaGuard non-contact safety switches are Category 4/SIL 3 rated switches per EN954-1, TÜV 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, improving 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, SensaGuard 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 feature helps reduce machine wiring costs. SensaGuard also contains built-in diagnostic capabilities. Green LED lights let operators know a machine is running safely. If a failure occurs, the unit’s LED blinks red, alerting operators directly to the problem switch, which reduces troubleshooting and maintenance time.
SensaGuard is ideally suited for a wide range of industrial-safety applications , including those that utilize 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.
