The digital encoder is always used with motors to feedback the shaft position of the motor. Rotary optical encoder has the features of light weight, compact size, high precision, low price, high quality ,imported bearings and high protection class .The rotary transducer is widely applied in light industry such as printing and packaging industry.

Motor shaft encoder is one type of rotation sensor. Currently, it is the most often used sensor. The motor shaft encoder includes optical disc and photoelectric detecting parts. The optical disc and motor shaft rotate at the same speed. The led electrical parts detect it and output pulse signals at the same time.

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.

Stepper motor is the executing parts and encoder is the feedback system. Encoder is used with stepper motor and PLC controls them. PLC sends the pulse command to the stepper driver. The driver supplies the current to stepper motor and make it run. And encoder will feedback the current position information to PLC. PLC will compare the feedback value with the target value and make adjustment of the rotter. DC motor with encoder is an important part in the open loop system.

The incremental optical DC motor encode passes the certification is CE ISO9001 & ROHS and the manufacturer of the sensor has high quality control, better delivery control and better cost control.The hollow shaft encoder apply to the lift, textile machines, cnc machine tools, packing machines and conveyor industry.

The servo motor encoder is in modular design. There is no housing. It can be directly mounted into the back of the servo motor. 35mm OD size is smaller than common type of servo motor encoders. The function is the same and it is with low cost. In recent years, along with the popularization of automation, intelligence, miniaturization, modular type encoders have been welcomed more and more. The structure of modular type encoders is more compact compared with other encoder. It reduces production costs.

Servo motor and encoder are two important parts in servo motor control system. This rotary encoder is small in size. But its resolution is high. Single turn resolution reaches to 21 bit; multi-turn resolution reaches to 32 bit max. The motor encoder is necessary part of servo motor. The encoder resolution decides the precision of servo motor angle, position and speed measurement. Incremental type motor encoder has been widely applied in servo motor system. But for high resolution requirement industry, absolute type servo motor encoder is required more and more.

Each servo motor is including a optical encoder. If a servo motor does not have a encoder, it can not be called servo motor. Encoder feedback function is important for servo motor. Servo motor has the obvious advantage in precise positioning than stepper motor in precise control system. Stepper motor is an open loop system. Servo motor is closed loop system. Servo motor system has higher anti-vibration even when low speed operation.
