Coded Disc Encoder 50pcs 20 Holds Speed Sensor for Robots by Chironal

Description

Product Overview

The Chironal coded disc encoder set is engineered for high‑precision speed measurement in robotic applications. Each package contains 50 individual disc encoders, each capable of providing 20 distinct hold positions, allowing for fine‑grained motor speed control and repeatable testing scenarios. Constructed from durable, high‑grade polymer, the discs resist wear and maintain accuracy over thousands of cycles. The compact form factor—measuring just 4.37 x 3.15 x 0.87 inches—and a lightweight of only 2.18 ounces per unit ensure that the encoders can be mounted on a wide variety of motor shafts without adding significant bulk or inertia.

Technical specifications include a clear, laser‑etched coding pattern that the sensor reads with a built‑in photodiode array, delivering reliable pulse signals even in environments with ambient light fluctuations. The encoders operate on a 5 V supply, making them compatible with most standard robotics control boards and microcontroller platforms. With a fast response time of less than 1 ms, the system provides real‑time feedback essential for closed‑loop speed regulation, PID tuning, and performance benchmarking.

Usage

Designed for both professional engineers and robotics hobbyists, this encoder set excels in a variety of use cases. In educational labs, students can experiment with motor control algorithms, observing how changes in PWM duty cycle affect speed and how the encoder feedback stabilizes the system. In industrial prototyping, developers can integrate the encoders into autonomous mobile robots, conveyor systems, or robotic arms to monitor joint velocities and ensure smooth operation.

The robust construction allows the encoders to function reliably in dusty workshops, temperature‑controlled labs, and even outdoor field trials where exposure to moisture and debris is common. Because the sensor interface is simple—requiring only power, ground, and a single signal line—installation is straightforward, reducing wiring complexity and minimizing potential points of failure.

FAQ

What motor sizes are compatible with these encoders?

The encoders are designed to fit shafts ranging from 3 mm to 6 mm in diameter. Mounting holes are provided on each disc to accommodate standard set‑screw sizes, and adapters are available for larger shafts.

Can the encoders be used in environments with high ambient light?

Yes. The built‑in photodiode array includes a narrow‑band optical filter that reduces interference from ambient lighting, ensuring reliable pulse detection even in brightly lit settings.

Do the encoders require any special drivers?

No special drivers are needed. The encoder outputs a simple digital pulse signal that can be read by any microcontroller or PLC with a digital input. Sample code for popular platforms is included in the documentation.

Is there a warranty on the product?

All Chironal encoders come with a one‑year limited warranty covering manufacturing defects. Our support team will replace any faulty units at no cost within the warranty period.

How many encoders can I use simultaneously?

The system is designed for scalability. You can connect multiple encoders to separate input channels on your controller, or use a multiplexing scheme to read several encoders on a single channel, depending on your application’s architecture.
