Encoder Accuracy vs Resolution
Non contact encoders or shaftless encoders offer a compact, rugged package with no shaft, couplings, bearings or seals to wear out. Designed with the form factor of a traditional proximity sensor, our non contact encoders or non contact rotary sensors can offer position data. A wide sensing envelope and means design flexibility and allows for the sensor to work even the magnet is misaligned or offset from the sensor. Encapsulated electronics with no moving parts means Dynapar's non contact encoders excel in environments with extreme temperature, moisture, high shock and vibration , such as agriculture, farming, construction, forestry and food and beverage.

Non contact encoders track rotation with a physical connection to the rotating shaft. Non contact encoders most commonly use magnetic hall effect sensors to sense the change in magnetic poles as a target magnet rotates along with the shaft.
Non contact encoders are often used in harsh heavy duty environments because they do not need a physical connection to the tracked rotation. This eliminates the need for bearings and sealing, which can act as a point of failure in the feedback system.
There are two parts of the non contact encoder, a sensor and target magnet. The target magnet mounts to the shaft and the sensor faces the magnet. As the shaft and thereby target magnetic rotate, changes in magnetic poles are tracked by the sensor to generate encoder pulses.
