General description
JSNY8 is a safety interlock switch with a locking function. The switch can only be actuated using a corresponding
triple coded actuator and can be mounted in any direction (the switch head can be rotated 4x90 degrees). The
actuation direction can be either linear or radial by using a specific actuator. The holding force is 1000 N.
Caution!
The actuator must be inserted into the head during the rotation of the head.
Additionally, the JSNY8 is tamper-proof (the switch cannot be actuated with screwdrivers, magnets or other tools).
The switch is well suited to lock a door or hatch to prevent access to machines:
When the machine perform tasks that are not allowed to be stopped during the process, e.g. welding
When the machine have long stopping time, e.g. paper machines with a long brake process
To keep unauthorized persons away from a certain area
NB: To reach a high safety level when connected to the machine control system, it is recommended to use an
ABB/Jokab Safety safety relay, Pluto safety-PLC or a Vital safety module with a Tina adaptor unit.
Warning!
In order to maintain the safety level the actuator may only be procured and used as an integral part of
the associated asfety switch.
