This product is used where the controlled isolation of a machine or process needs to take place, i.e. where a robot has to finish a cycle prior to isolation or temporisation, zero speed position, temperature level. With the product, the key(s) can only be released when an electrical signal is given to the solenoid (when it’s energised or not energised). The solenoid then changes its position and allows the key or keys to be rotated. System available from 1 to 3 cylinders depending on your application.
