Magnetic Rotary Encoders

Because magnetic rotary encoders are based on an inductive effect, they do not require bearings, which removes a point of failure from the system. Combined with encapsulated electronics, magnetic rotary encoders are extremely robust, can handle extreme temperatures, shock, vibration and ideal for environments with dirt, dust and oil. Dynapar offers incremental magnetic rotary encoders with up to 2,048 PPR resolution and absolute models with up to 16 bit multi-turn resolution.

Frequently Asked Questions about Magnetic Rotary Encoders

What are magnetic rotary encoders?

Magnetic encoders are a type of rotary encoder commonly used in applications with harsh conditions such as dust, moisture extreme temperatures and shock. Magnetic encoders detect changes in perturbations to magnetic fields to provide reliable digital feedback.

How do magnetic rotary encoders work?

Magnetic encoders use a magnetic sensor to detect changes in perturbations to magnetic field on an encoder wheel or drum. The magnetic response is converted to a digital signal and sent to the controlling device.

What are the advantages of magnetic rotary encoders?

Unlike optical encoders, magnetic encoders do not depend on a disc and light source that can be affected by contamination such as dust or moisture and are more resistant to extreme temperatures, high shock and vibration. Magnetic rotary encoders are more reliable and reduce downtime in applications with harsh environments.

When should you use a magnetic rotary encoder?

Magnetic rotary encoders are built robust and should be used in facilities such as steel, pulp, paper and lumber mills. Position and velocity applications that require broad temperature specifications, high shock and vibration resistance, robust sealing, and contaminant protection are ideal for magnetic encoders
