Encoders Rotary Encoder
Rotary encoders are small, thin, and lightweight incremental encoders.
- Incremental type, 30 mm diameter
- Resolution: 100~4000 P/R (14 types)
- Line Driver Output, Voltage Output, Open-Collector Output


Features
Small, Thin, and Lightweight Incremental Encoder
Outer diameter φ30mm, depth 22mm, mass 33g (round shaft type) / 38g (hollow shaft type), small, thin, and lightweight, allowing installation in tight spaces.

Despite its small size with an outer diameter of φ30 mm, the product line offers resolutions ranging from 100 P/R to a maximum of 4000 P/R
14 types are available, including resolutions that are easy to combine with stepper motors and those suitable for the desired step angle.
A wide variety of output circuit types available
Three types of output circuit are available: line driver output, voltage output, and open-collector output.
Can be used in high temperature environments up to 85 °C
The Actual Position, Speed, and Rotation Direction of the Mechanism Can Be Detected
By attaching a rotary encoder to the mechanism, a predictive maintenance system for the mechanism can be established.
- Application Example
In belt and pulley mechanisms, it is possible to detect the difference in rotation between the motor and mechanism due to belt deflection or breakage

Easy Alignment of Mechanical Home and Z-phase Signal
The Z-phase signal is output at the position where the shaft milling cut section (round shaft type) or the fixing screw section (hollow shaft type) is rotated 180° from the encoder connector. Use this as a guide when adjusting the positional relationship be tween the mechanical home and the Z-phase signal.
