Small, Thin, and Lightweight Magnetic Incremental Encoder

Since these rotary encoders are small, thin, and lightweight, they can be installed in tight spaces. Encoder resolutions vary from 100 to 4000 P/R. These rotary encoders are available in round shaft type or hollow shaft type with voltage, line driver, or open collector output. It can detect the actual position, speed, and direction of rotation of conveyors, belts, pulleys, and other mechanisms, contributing to the construction of predictive maintenance systems.

 

Magnetic encoders do not use a light emitter or a light receiver but still use a code wheel and a sensor. Instead of slits, the code wheel has alternating north and south pole magnets on the outer edge of the code wheel. The magnetic sensor senses changes in magnetic polarity when the poles pass by. The end result is the same as the output circuit outputs pulses to a PLC or HMI. Since there's no need to power the light emitter and receiver, the magnetic encoder uses less power than an optical encoder.

Magnetic encoders are more robust than optical encoders in the sense that they can operate better in humid, dusty, or dirty environments. However, magnetic encoders may not work well in an environment with magnetic interference. Magnetic encoders are also offered in rotary, linear, incremental, and absolute types. To enable a magnetic encoder to track absolute positions, multiple magnetic disks are necessary.

Dustproof and Water-Resistant IP65 Type

This product is dustproof and water-resistant to IP65 standards, meaning it can be used without being affected by dust or water droplets. No cover is required, and it can be installed as is.

Actual Position, Speed and Rotation Direction of the Mechanism can be Detected

By installing a rotary encoder on a mechanism, a preventative maintenance system for that mechanism can be created.

Can Be Installed to Suit the Mechanism

Aligning Mechanical Home and Z-Phase Signal Position is Easy

The Z-phase signal is output at the position where the shaft flat (round shaft type) or the fixing screw (hollow shaft type) has rotated 180˚ from the encoder connector. Use this as a guide when aligning the mechanical home and the Z-phase signal position.
