The Basics of How an Encoder Works

An encoder is a sensing device that provides feedback from the physical world; that is, it converts motion to an electrical signal that can be read by some type of control device.

A New Approach to Interpolated High Resolution Encoders

Encoder digital signals start as sine waves and can be interpolated to produce higher resolutions. Sine waves have to be clean and free of noise for effective interpolation.

Encoders in Inhospitable Environments

Encoders are often used in harsh industrial environments. Encoders can be exposed to the same contaminants other machinery is, including: high volumes of dust, an abundance of moisture, caustic chemicals, even physical damage, where the encoder is knocked around by other equipment.

Selecting Digital Encoder Outputs

The output type for an encoder is an important consideration when specifying an encoder for a motion control application. The first consideration is the number of output channels, and the second consideration is the receiving device.

Shaft Loading and Sealing vs. Bearing Life Expectancy

The mechanical life of an encoder is mainly determined by the life of the unit’s bearings. Several factors affect bearing life, including shaft loading, heat, ingress, and rotational speed.
