 End stop bolts GN251.1 are supplied with a hardened round head which serves as a firm end stop. In general these bolts are installed with a locknut.

When the workpiece contacts the bolt head an electrical signal is transmitted by means of the limit switch.

Attention:

If the screw-in thread is earthed, the blue cable has to be connected to the mass.
