Elesa+Ganter Spring plungers 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.
Attention: if the screw-in thread is earthed, the blue cable has to be
connected to the mass.
