Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All medium duty 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. Totem Pole (push-pull) outputs guarantee that these encoders are compatible with sinking or sourcing input modules. Line Driver versions are also available. Mounting brackets and flexible couplings in aluminum and glass reinforced resin are also available.

Availability
All of our Koyo encoders are in stock and available to be shipped immediately.

Price
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 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.

Quality
All encoders carry a 1-year warranty, and all in-stock models 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.

Medium duty incremental encoders start at $109.00 (TRDA-20R1N100RZD)
