Industrial Grade Optical Rotary Encoders
Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All Koyo encoders feature a reinforced aluminum diecast casing and come equipped with a two-meter cable or MS connector.
Use the incremental encoders with our PLC high-speed counter modules for accurate position monitoring and control. Absolute encoders are wired to standard PLC DC input cards and do not require a high-speed input module. Mounting brackets and flexible couplings in aluminum and glass reinforced resin are also available.
All of our Koyo encoders are in stock and available to be shipped immediately.
As with all of our product lines, our prices are often well below the list prices of traditional automation suppliers. Our direct business model allows us to operate more efficiently than other suppliers and pass the savings on to you. A light-duty encoder is a cost-effective encoder for light shaft loads.
All encoders carry a 1-year warranty, and have a 30-day money-back guarantee. If for any reason you are not satisfied with your purchase, send it back and we will refund your money.

A light-duty encoder is a cost-effective encoder for applications not requiring much of a load on the shaft. These encoders are perfect for industrial applications with good mounting conditions and flexible shaft couplings.
A medium-duty encoder is the most popular encoder we offer. The product line offers the greatest flexibility of choice while maintaining very 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.
An absolute encoder uses gray code (a version of binary where the physical inputs only change state one bit at a time) to describe each position, so position data is not lost when power is cycled.
SureStep® Stepping System replacement and optional encoders. Replacement encoders for integrated motor/drives. Optional encoders for standard integrated motor/ drives and standalone dual-shaft motors in all NEMA 14, 17, and 23 sizes.
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. Couplings are available for all solid shaft encoders. Cables and connectors are available for TRDA-25 series encoders with MS connectors
