Encoder Wheel 20 Slots 26mm

ENCODER WHEEL

The Encoder Wheel – 20 Slots is a simple yet effective mechanical component used to detect rotational motion in motors and wheels. It consists of a circular disk with 20 evenly spaced slots or cutouts, designed to work with an optical or infrared sensor. As the wheel rotates, these slots pass between a light source and a detector, allowing light to intermittently reach the sensor. Each time a slot passes through the sensor’s detection area, it generates a digital pulse. With 20 slots, the wheel provides 20 pulses per full rotation, making it suitable for low-resolution motion tracking and rotational feedback.

This encoder wheel is often made from lightweight materials like plastic or acrylic, ensuring it doesn’t add significant load to the motor shaft. It typically has a central hole that allows it to be mounted directly onto a motor shaft, making it a convenient choice for robotic and automation projects. The spacing and precision of the slots are critical in determining the accuracy of the encoder system.

The Encoder Wheel – 20 Slots is widely used in DIY electronics, robotics, educational projects, and entry-level automation systems. It’s ideal for applications such as measuring wheel rotation, calculating distance traveled, or monitoring the speed of a DC motor. When combined with a microcontroller like Arduino or Raspberry Pi, it can be used to build simple yet functional closed-loop control systems.

Although it provides a relatively low resolution compared to high-slot encoder wheels, it is perfect for basic feedback systems where high precision isn’t essential. It offers a balance of simplicity, affordability, and practical functionality, making it an excellent tool for students, hobbyists, and makers exploring motion detection and control.
