Balluff Unveils RFID Safety Guard Locking Switch

Balluff has expanded its safety product line with the release of its latest non-contact RFID safety guard locking switch. The switch combines non-contact, coded-transponder safety technology with a mechanical solenoid locking function to meet the safety levels required by international standards.

This switch can be connected directly to Balluff's IO-Link safety I/O module or to any safety controller using a standard eight-pin M12 connector. The high coding level provided with RFID technology couples sensor and actuator with a unique code, the company reports, and offers tamper-proof protection and high-level coding according to the EN ISO 14119 standard. A rotating shaft and capstan handle can be held locked in the closed position until the process has run down and stopped. Integrated safety processing electronics and OSSD outputs enable its use in applications requiring PLe (EN ISO 13849) and SIL 3 (IEC 61508) ratings.

The switch is designed to meet the needs of a range of applications, according to the company. It is suitable for securing and safely monitoring guard doors and safety flaps to protect individuals from potential hazards, or to prevent the interruption of processes. The guard-locking function keeps the guard or gate closed until the process is stopped and it is safe to access the machine.

A selectable latching force of 25 N or 50 N makes the guard lock insensitive to vibration, even when unlocked. Typical applications for the non-contact RFID safety guard locking switch include doors, gates and guards on packaging machines, machine tools, robot cells and plastic injection molding machines.
