Background

The knob is a manual element that is turned by hand. The rotation angle can reach 360 degrees, and the positioning rotation can be carried out. The classified shapes can be divided into a round knob, a polygonal knob, a pointer knob, a manual rotating disc and the like.

The knob needs to be matched with a rotary encoder to realize the effect of rotation regulation in actual use, the rotary encoder is a device which is used for measuring the rotating speed and can realize quick speed regulation by matching with a PWM (pulse-width modulation) technology, and the photoelectric rotary encoder can convert mechanical quantities such as angular displacement, angular speed and the like of an output shaft into corresponding electric pulses to be output as digital quantities (REP) through photoelectric conversion. The output is divided into a single-path output and a double-path output. The technical parameters mainly comprise the pulse number per revolution (dozens to thousands of pulses exist), the power supply voltage and the like.
