Rugged and reliable interlocking device and guard locking devices
Safety switches with a separate actuator are protective devices which simultaneously provide personal and machine protection. Together with a machine controller and a guard, they control access to a hazardous area. Depending on the application requirements, safety switches without guard locking, with mechanical guard locking (power-to-unlock) or with solenoid guard locking (power-to-lock) can be used.
Balluff's family of mechanical safety switches include multiple options to satisfy a range of applications including packaging, food & beverage, automotive, robotics, assembly, factory automation and many others. The family includes a standard tongue switch and several guardlocking variants, to protect personnel and/or processes. These switches can be used to "lock" guards and doors until the process has safely come to a halt.
The Mechanical Safety Switches can be connected to any safety processor, i.e. to safety relays, programmable logic modules or safety controllers. Wiring is simple using standardized M12 plug connections - the safety switch is "plug & play" with the Balluff safety IO-Link I/O module. And when properly applied with a safety controller, these switches can meet a high level safety per EN ISO 13849 and IEC/EN 61508/62061.
