Optical Rotary Encoder

What is the optical rotary encoder?

The optical rotary encoder is a device that measures the speed and enables fast speed regulation with PWM technology.

The optical rotary encoder converts the mechanical quantities such as angular displacement and angular velocity of the output shaft into a corresponding electrical pulse for digital output (REP).

There are two types of outputs, single and double.

The main technical parameters are the number of pulses per revolution (dozens to thousands), and the supply voltage. A single output means that the rotary encoder outputs one set of pulses, while a dual output rotary encoder outputs two sets of pulses with a 90 degree phase difference between the A/B’s. These two sets of pulses not only measure the speed but also determine the direction of rotation.

How to install this Optical Rotary Encoder?

Do not apply direct impact to shaft during installation.

Flexible connectors shall be used to connect the encoder shaft to the machine. When mounting connectors on shafts, do not force-feed. Even if the use of connectors, due to poor installation, it is possible to add more load to the shaft than the allowable load, or cause core pulling phenomenon, therefore, to pay special attention.

Bearing life is related to service condition, especially influenced by bearing load. If the bearing load is less than the specified load, the bearing life can be greatly extended.

Do not disassemble the optical rotary encoder, as this will damage the oil and drip resistance. Anti-drop products should not be long-term immersion in water, oil, water surface, oil should be wiped clean.
