Limit Switches FCN Series TM

Limit Switches FCN Series Main features The rotary limit switch series FCN is a device which allows you to control the movement of industrial and building machines. The shaft is connected to the motor, so that, after a certain number of turns, the cams allow the switches to work, and then they can carry out their pre-set manoeuvre. The range of FCN rotary limit switches has been planned with a particular internal symmetry that allows you to have a series of 5 microswitches and an additional linear potentiometer. The series includes a number of optional accessories, which make mechanical...

Calibration criteria Each cam is equipped with its own micrometer regulating screw. Each screw operates exclusively on the cam it is combined with, without interfering mechanically against its adjacent cams. Regulation can simply be carried out by rotating the regulating screw through a small blade screwdriver. Thanks to a particular friction system, rapidity and regulation precision are assured, which makes the structure stable, steady and reliable.

Potentiometer The insertion of a potentiometer near the microswitch group involves a linear exit in the same box. Regulation • Ensure that the locking screw (A) is loosened. • Set the desired resistance value by means of the instruments by rotating the regulating ring(B) clockwise (C) to reduce it, or anti-clockwise (D) to increase it. • Tighten the lock screw (A) IMPORTANT: The potentiometer follows the cams rotation direction.
