2 Limit switches Rotary Gear product description Rotary Gear Limit switches page 6 to 35 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, 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. Ratio Potentiometer & Encoder 0 rpm The Giovenana s rotary gear limit switch are available in different transmission ratio. The ratio is the difference between the number of rotation of the main shaft and the number of rotation of the cams. 000 rpm Picture shows a FGR//3 working on a crane system 6 Ratio gear 050 In addition to the microswitch : FGR line: available with potentiometer (direct ratio :) FGR3 line: available with potentiometer or encoder having: direct ratio : or ratio :X (X=cam block ratio) Potentiometer in FGR Picture shows a FGR//3 working on a rolling shutter door
