High-Precision Shaft Encoders for Accurate Motion Control

Best Shaft Encoder for Machine Control

A shaft encoder is a device that is used to measure the turning motion of a shaft. It sends an electrical signal to a machine’s main computer, or controller. The controller uses this signal to know the exact position and speed of the spinning part. This information is needed for the machines to do its work the right way.

At Briterencoder, we make a number of different shaft encoders for industrial work. Our parts are made with strong metal cases to protect them from damage in a busy factory. We test our encoders to make sure they work correctly and for a long time. Our team can also help you pick the right model for the machine that you are building.

How a Shaft Encoder is Built and Used

Our encoders have a simple design and do a clear job for your machine:

• How It Measures Rotation: A rotary shaft encoder is attached to a spinning part in your machines, like the shaft of a motor. Inside the encoder there is a small disc that has many lines printed on it, almost like the spokes of a wheel. As the shaft turns, this disc spins past a small light sensor. Every time a line passes the sensor, it breaks the light beam which creates a single electrical pulse that is sent to the controller.
• Parts of The Device: Our encoders are made with a strong metal body or case. This case protects the small electronic parts on the inside from things like dust and moisture. A solid steel shaft with strong bearings sticks out from the body of the encoder which you will connect to the part of your machine that you need to measure. It is built to handle the stress of industrial use.
• How To Install It: To install a shaft encoder correctly, you must use a separate part called a flexible coupling. This small piece is what connects our encoder’s shaft to your motor’s shaft. Using a coupling is a very important step because the coupling is a little bit flexible, and this flex stops any vibration from your motor from breaking the small and precise bearings inside the encoder, helping it to last a long time.
• The Incremental Signal: This incremental shaft encoder sends out a simple stream of electrical pulses as it spins. Your machine’s controller just counts these pulses to know how far the shaft has turned. This makes it a very simple and direct way to get the information you need, especially when you need a shaft encoder for motor speed control.

Build Your Machine with the Best!

A shaft encoder is the right tool to use when you need a machine to measure the turning of a part. It does this by sending a simple electrical pulse for each small bit of rotation. Its ability to give this information in a clear way is very useful for many kinds of jobs. This is why you will find them in machines that need to do very exact work, like conveyor belts and robotic arms. They are an important part for building machines that can be controlled with precision. Look at our models or contact us for help if you need a shaft encoder for your machine.

Frequently Asked Questions

1. What is a Hollow Shaft Encoder?
   A hollow shaft encoder is different because it has a hole all the way through its middle. It does not have a solid shaft that sticks out like this model does. You install it by sliding it directly over the end of your motor’s own shaft and then clamping it on so it does not slip.

2. Do You Need a Coupling to Install This?
   Yes, for this type of solid shaft encoder, you will need to use a flexible coupling to connect it to your motor. A coupling is a separate part that connects the two shafts together. This is a needed step because it protects the encoder from any wobble from the motor shaft.
   
   
3. How Do You Know the Resolution of the Encoder?
   The resolution of the encoder is listed on its data sheet as a number called PPR, which means Pulses Per Revolution. This number tells you exactly how many electrical pulses the encoder will send out for every one single, full turn of its shaft. A higher PPR number means the encoder can measure smaller amounts of movement.
   
   
4. What is an IP Rating on an Encoder?
   The IP rating is a two-digit number that tells you how well the encoder’s case is sealed against things like dust and water. The first number is for protection against solids like dust, and the second number is for protection against liquids like water. A higher number means it has better protection for use in a hard work environment.
   
   
5. Why Does the Cable for the Encoder Need a Shield?The shield is a metal wrap that is inside the cable, around the signal wires. Its job is to protect the small electrical signals that the encoder sends out from any outside electronic noise from other machines in your factory. Using a shielded cable is important to get a clean and correct signal to your machine’s controller.
