Dear colleagues, hello

A line driver is a type of rotary encoder that is designed to transmit the signals generated by the encoder over long distances. The line driver typically consists of a circuit that is integrated into the rotary encoder and is responsible for converting the low-level signals generated by the encoder into a stronger, more robust form that can be transmitted over longer distances without degradation. This is typically accomplished through the use of voltage or current amplification, as well as other techniques such as noise reduction and signal conditioning. Line driver rotary encoders are often used in applications where the encoder and the device it is connected to are physically separated by a significant distance, or where the signals generated by the encoder need to be transmitted through noisy or electrically noisy environments.

What is meant by line driver?

A line driver is a type of circuit that is used to transmit signals over long distances by converting them into a stronger, more robust form that is less susceptible to degradation. This is typically accomplished through the use of voltage or current amplification, as well as other techniques such as noise reduction and signal conditioning.

Line drivers are often used in applications where the device generating the signals and the device receiving the signals are physically separated by a significant distance, or where the signals need to be transmitted through noisy or electrically noisy environments. Line drivers can be used with a variety of different types of signals, including electrical signals, digital signals, and analog signals. They are commonly found in a variety of different applications, including communication systems, industrial automation systems, and other types of electronic systems.

One of the biggest advantages of a line driver encoder is the ability to transmit signals over long distances without loss or interference. In standard output types, after a few meters you start to see signal loss and noise, but with a line driver circuit, differential output makes data transmission much more reliable, even in industrial environments.

If your cable route runs near motors, drives, or other noise sources, line driver is a must. The dual-channel (A, /A, B, /B) signal system guarantees signal integrity and helps reduce maintenance headaches.

But don’t forget: your PLC or counter should also support differential input. Otherwise, you won’t get the full benefit of your line driver encoder.

In short, with a line driver encoder you get long-distance, high-security, and low-error transmission. Especially in heavy industry, cranes, conveyors, and noisy environments, it’s the smart choice. If installed correctly, it will run for years — stable and trouble-free.
