Encoder Accuracy vs Resolution
Dynapar offers miniature rotary encoders and commutation encoders with diameters less than 2 inch for feedback applications in tight spaces. Several super-compact modular encoders for small servo and stepper motor feedback are also available designed to replace size 10, 11, 15 resolvers in motor applications. Models with h phased array sensor technology allows for axial shaft play and provide high performance encoder feedback in high shock or vibration environments. Dynapar also offers miniature encoders designed with wide operating temperature ranges and various PPRs up to 5,000 PPR and commutation track or pole options.

A miniature encoder is a small encoder that is used in applications where weight and space are major constraints. Miniature encoders can be either absolute or incremental and are popular in robotic joint and servo control applications where space is limited.
The main types of miniature encoders are incremental and absolute based on feedback type. Incremental miniature encoders provide speed, direction and relative position to an index location, while absolute miniature encoders provide unique output bits for each position.
Miniature encoders typically mount to a motor shaft via hollow-shaft or thru-bore mounting configurations where the shaft passes through the center of the encoder. Miniature encoders are then fixed via adhesive or integrated tethers while the thru-bore collar is connected to the rotating shaft via clamping mechanisms.
