How to apply ES38 NPN output rotary encoder to MCU

The ES38 series rotary encoder produced by CALT sensor has a variety of outputs to choose from: NPN (8-24V power supply), PNP (8-24V power supply), Voltage (5V power supply) . Usually we recommend that customers purchase voltage output encoders directly if they are used in single-chip microcomputers, but what if you accidentally purchase the wrong …

High protection grade encoder housing design comes from CALTSENSOR

All-metal screwless sealing grade: This sealing technology does not use screws to fasten the outside of the encoder, but a one-time shell squeeze seal, which can ensure that the protection grade of the encoder shell reaches IP67. Especially the outer circle part of the encoder housing does not use three or four screws, which avoids …

Encoder mounting to find and calculate the zero position

Generally, incremental encoder provides a z phase (zero) signal each circle, and for absolute encoder, each position data value is unique, so there is also a zero position. So, how to determine zero position in using of encoder? Usually there are several ways: In the installing encoder, rotate shaft to determine zero position. Usually, incremental …

Resolution and accuracy of absolute encoder

Encoder resolution and accuracy is not necessarily equivalent. Accuracy by the engraved lines, encoder mechanical concentricity, reading response speed, temperature characteristics and other factors determined. If an encoder is sinusoidal groove segments high resolution, then it does not improve the accuracy of, subdivision only improves resolution. Accuracy before and after subdivision does not change, so …

what is a rotary encoder and how does it work?

Introduction: Rotary Encoder Rotary encoders are position sensors used for determining the angular position of a rotating shaft. They convert the angular position or motion of a rotating shaft axle into analog or digital output signals. There are two main types of rotary encoders- absolute encoder and incremental encoders. The different types of rotary encoders, …
