GN 251.2 Stop Bolts Steel, With Limit Switch


GN 251.2 Steel Stop Bolts, With Limit Switch

Product description


GN 252.5 stop bolts are supplied with a hardened round head that serves as a firm end stop. Typically 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 removed without need for loosening the setting bolt.

Note: If the screw-in thread is grounded, the blue wire has to be connected to the workpiece.
