Rotary Gear Limit Switches Brochure

The Giovenzana’s rotary gear limit switch is a device used to control the number of rotation or direction angle of industrial and building machines. A typical application is controlling the position of the rolling shutter door or overhead cranes etc… .

The unit, through a gear system and cams transmission, controls 2, 4 or more microswitches so that after a definied number of revolutions, it can prepare the motor or the device to start or stop running.

The microswitches have a calibration screw that operates independently on each cam; so it can calibrate the opening and closing of each micro according the functional requirements needed.

The gear-based transmission system allows you to choose different ratios. It can also be supplied with rear shaft version or complete of linear detector (potentiometer or encoder) too.
