Product Description

GN251.2 Setting Bolts, with Limit Switch, Steel

Setting bolts GN 251.2 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.

By means of the knurled nut, the limit switch can be installed and taken out without having the need to loosen the setting bolt.

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