The Giovenzana's rotary gear limit switch is a device used to control the number of rotation or direction angle ofindustrial and building machines. A typical application is controlling the position of the rolling shutter door oroverhead cranes etc.. . The unit, through a gear system and cams transmission, controls 2, 4 or moremicroswitches so that after a definied number of revolutions, it can prepare the motor or the device to start orstop running. The microswitches have a calibration screw that operates independently on each cam; so it cancalibrate 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.

Ratio
The Giovenana's rotarygear limit switch areavailablein differenttransmission ratio.The ratio is the difference between the number ofrotation of the main shaftand the number of rotationof the cams
Potentiometer & Encoder
In addition to the microswitch :"FGR1 line: available withpotentiometer(direct ratio 1:1)"FGR3 line : available withpotentiometer or encoderhaving:direct ratio 1:1 or ratio 1:X(X=cam block ratio)
