When the incremental rotary encoder shaft rotates, there is a corresponding pulse output. The discrimination of the direction of rotation and the increase or decrease of the number of pulses are realized by the rear direction judgment circuit and counter. The starting point of the counting can be setting freely, and the infinite cumulative and measurement of multiple circles can be realized. When the number of pulses is fixed and the resolution needs to be increased, the original pulse number can be multiplied by using two signals of 90° phase difference A and B.

Rotary encoder is the sensor which could convert the shaft mechanical displacement to digital or pulse signals. On the incremental encoder disc， there are many square holes equally spaced. The rotary encoder could output the pulse signal through the electrical part reading the holes on disc.

Optical rotary encoder has the features of versatile, compact and flexible, photoelectric sensing technology, high accuracy, high precision, heavy duty bearing, long lifetime,high frequency response, universal mounting dimensions and high resolution. Optical pulse encoders apply to the lift, textile machines, cnc spindle, packing machines and conveyor industry.

The rotary incremental encoders passed the certification of CE ISO9001 & ROHS and the manufacturer of the incremental encoder has high quality control, better delivery control and better cost control.The rotary incremental encoders are applied to the lift, textile machines, cnc machine tools, packing machines and conveyor industry.

CNC Rotary Optical Encoder Spindle Motor Encoder is an optical rotary spindle motor encoder used in CNC controller.STS series encoder electronic devices are imported from the USA, and optical components are integrated form photoelectric switch modules. The quality is stable and reliable. The grating is made of vibration resistance and high temperature resistant material, which can bear more than 3 times of shock and vibration of the traditional encoder.

Non contract magnetic ring encoder equipped with the seven different size. The location sensor highest resolution is up to 16384ppr, which can satisfy with the different size of the spindle motor encoder. the sensor is made of the ABZ three phase output`s read head and magnetic source body. The machine encoder read head and magnetic source body sealed in metal shell, and output the industry standard ABZ wave square signals. ROUNDSS rotary magnetic ring encoder with the same advantage as integrated encoder, no need to change the original synchronous pulley and mount it at the position of original synchronous pulley
