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, 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 application 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 LED blinks 'Red', alerting operators directly to the problem switch, and helps to reduce troubleshooting and maintenance time.
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.
SensaGuard is ideally suited for a wide range of industrial-safety applications in all manufacturing markets, including those that utilise high pressure wash downs, such as automotive, food, beverage, packaging and material handling.
SensaGuard is IP69K environment-rated, and also offers short-circuit and overvoltage protection. Request a free brochure from Rockwell Automation ...
