Features and applications

Safety indexing plungers GN 414 in type A and C are used when the inadvertent retract of the plunger pin is to be prevented. The plunger pin is locked in one or both end positions and can be unlocked only with the red safety push button.
Types B and C also feature an index lock if the plunger is not to protrude temporarily, i.e. if it is to be held in the retracted position.
In every case, the safety lock engages in the front end position, i.e. automatically if the indexing pin protrudes, with the locking mechanism housed fully in the operating button and protected from malfunctions. The specified axial load bearing capacity refers to the locking force of the bolt against inadvertent operation which must not be exceeded.
