Only movement via control of your system

Thanks to this mechanical safety function, the cylinder cannot move without a signal being given from the control of your system; in all other cases, the locking pin will be pushed by spring force into the retaining groove of the piston rod.

Advantages compared to a piston rod lock

To install a piston rod lock, an extended piston rod must be used. As a result, the installation length is no longer in accordance with ISO 15552.
The maximum holding force of a piston rod lock is limited; if this value is exceeded, the cylinder will still start to move.
No additional air connections are required. The release activation is controlled by internal air.
