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.

The hollow shaft encoder sensor specially designed for dc UVW motor control. The design of shaft sleeve saves the mounting space and cost suit more environments. The special tapering shaft is easy to installation. The level of Hall signal can reach level 8. Resolution is up to 2000 PPR. Other specifications on request. Besides the incremental type servo mor encoder, roundss also supply absolute type hollow shaft encoder for motor.

Absolute encoder can be divided to 3 types in mechanical: shaft encoder, end hollow shaft encoder and through hollow shaft encoder. Shaft absolute encoder needs some extra part like flexible coupling to connect the shaft of motor and the shaft of encoder. Hollow shaft encoder can directly mounted to motor shaft and fix it with screws, clamp ring and brackets. Generally, the bigger size encoder is alway with hollow shaft design. The hole is from 4mm to 50mm or more. Howerver, for shaft encoder, the shaft diameter is always from 4 mm to 15mm.

Absolute shaft encoders has the features of high precision , high resolution ,high protection class, integrative technology, multiple mounting options. The optical absolute encoder sensor are divided into single-turn absolute encoder and multi-turn absolute encoder. This absolute shaft encoder is with brand new design. It is specially developed for national military project.

Roundss rotary shaft encoder as an incremental rotary encoder provides cyclical outputs (only) when the encoder is rotated. The incremental rotary encoder is the most widely used of all rotary encoders due to its low cost and ability to provide signals that can be easily interpreted to provide motion related information such as position and velocity.

Rotational encoder has different mounting ways. For end hollow shaft encoder, it will directly mount to the motor shaft and fix it with the mounting bracket. Generally, we will provide mounting bracket with the end hollow encoder together. And for some models, several mounting brackets are available to meet different mounting requirement.
