Overview
Compact, RFID high coded interlocks for safe access to machinery providing the highest level of safety up to Cat 4, SIL 3, PLe. For guard locking use Atom and for non contact gate switches use FRNK.
In line with guidance in ISO 14119, our compact solutions have high coded, uniquely paired actuators to reduce the possibility of defeat, their compact size and multiple mounting orientations make them simple to mount out of reach for further peace of mind. Designed for ease of install, they come pre-wired with quick disconnects and require just 2 mounting points each on the device and the actuator.
Atom – compact guard locking:
Guards which drop or become misaligned or even very tight spaces are no problem for the Atom. The clever tongue design has very high misalignement capability which works down to hatches as small as 150mm opening radius. Suitable for harsh environments due to open head meaning dust and dirt is pushed out of the unit during operation and means it is easy to maintain. OSSD dual channel safety channels with internal fault detection mean the devices can be daisy chained together to minimise wiring while retaining maximum risk reduction. A handy LED on the device shows what state the device is in, guard open, guard closed or a fault.

Access control in manufacturing
Fortress offers the ability to control who can access industrial equipment safely alongside when they can access safely. Data of who, when and where from access events is collated for efficiency analysis.
