Rotary encoders use an internal coded disc and a sensing head to sense the rotary position, useful in motion sensing applications such as machine tooling and multi-axis positioning. Incremental encoders output pulses that track relative position; absolute encoders output a value, retained through a power cycle.
Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All encoders feature a reinforced aluminum diecast casing and come equipped with a two-meter cable or MS connector. All kit encoders (for stepper motors) are ready-to-mount, with hardware and shaft adapters included.
Use incremental encoders with our PLC high-speed input modules for accurate position monitoring. Absolute encoders provide immediate position information on power-up (without a homing sequence) and can be wired to standard PLC DC input cards. Cables, mounting brackets and flexible couplings are also available.

A light-duty encoder is a cost-effective encoder for applications with light shaft loading. These encoders are perfect for industrial applications with good mounting conditions and flexible shaft couplings.
Medium-duty encoders are the most popular encoders, offering the greatest flexibility of choice with high quality, all for a very low price.
A heavy-duty encoder is the most rugged encoder you can buy. Top-of-the-line bearings help maintain a service life of 12 billion revolutions and allow significant loads on the shaft.
Absolute encoders use gray code (a version of binary where the outputs only change state one bit at a time) to describe each position, so position data is not lost when power is cycled AND the response frequency is slower for a given resolution.
SureStep® modular encoders for stepper motors and motor/drives are traditional optical encoders with convenient bolt-on options (dual shaft SureStep motors have the proper mounting holes predrilled). Replacement modular encoders for select SureStep® integrated motor/drives are also available.
Extremely rugged AMT series encoders from CUI Devices® use state-of-the-art capacitive technology and are available in fixed resolution or configurable models. Configurable models use either DIP switches or the free AMT Viewpoint configuration software to set the resolution (software also allows alignment of the Z-pulse)
Simplify your installation with ready-to-use couplings, mounting brackets / flanges, and wiring cables / connectors. Couplings provide a connection between encoders and solid shafts. We offer fiberglass and aluminum couplings for metric, S.A.E. and metric-to-S.A.E. applications. Signal & configuration cables and connectors are also available where optional or required.
