What Is An Encoder Used For?

What is an encoder used for?

Encoders are used in almost every industry where precise movement control is needed—they’re like the "eyes" of a machine, telling it where parts are and how fast they’re moving. Let’s break down some common uses: In the automotive industry, encoders on car engines track the crankshaft’s position, helping the engine run smoothly and save fuel. In printers, encoders control the paper’s movement so the ink goes exactly where it should. In elevators, encoders make sure the elevator stops right at the floor, not too high or too low.

Shanghai Hengxiang’s encoders are popular in these fields because they’re reliable and customizable. For example, their encoders for elevators have emergency stop signal outputs—if the elevator moves too fast, the encoder sends a signal to stop it immediately. For printers, Hengxiang makes small, lightweight encoders that fit in tight spaces without sacrificing accuracy. Also, their encoders have long service lives—many users report using them for 5+ years without issues. A common mistake: some people think encoders only work with motors, but they can also track linear movement (like a sliding door). Just make sure you choose the right type—Hengxiang has both rotary and linear encoders.
