Information

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 resp. taken out without having the need to loosen the setting bolt.
Operating instructions showing more important technical information are included with every setting bolt.
