Rotary Limit Switch FRM

Description

 

The rotary limit switch 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 make the switches work, and then they can carry out their pre-set manoeuvre.

The innovative and thorough regulation of the cams allows you to set the microswitches working point linearly and micrometrically.The limit switch ranges several ratios and you can assemble different kinds og sensors realizing varios linear outputs. Contacts are positive-opening, which improves the workers’ safe.

This series includes a great number of different accessories, which make easier the use of the limit switch.
