DIS Rotary Encoder

DIS Non-Contact Encoder Line

Our non-contact encoders, also known as shaftless or no-shaft encoders, are used to offer angular position data and to determine rotary speed and direction.

DIS offers several versions of encoders. Within each version, several part numbers exist. DIS offers an online configurator to assist with part number selection.

Address industrial position, size, and level measurement challenges.

DIS ROTARY ENCODERS measure rotational position with no contact and are truly completely sealed. Our sensors do not require any shaft coupling. Our sensors are based on the Hall Effect principle and address a need for simple, economical, and non-contact rotary sensing in OEM applications and for machine automation.

DIS rotary encoders consist of a sensing head and a magnet.

Each sensors is packaged with a neodymium magnet with distinct North Pole marking. We also offer a variety of magnets to fit your application as options.

DIS Sensors are rugged, accurate, cost effective, and are easily integrated into most customers’ control systems with their many output options, including Analog and incremental pulse outputs. DIS Sensors has been providing sensors to industry for the past 25 years around the globe and has a focus on the construction vehicle market.

We maintain USA inventory to provide you with quick delivery on certain standard products and offer a full line of accessories that help you integrate the sensors into your applications with minimal effort and searching for the right components.

Typical applications:
- Angular position – use in place of resolvers or potentiometers
- Used to determine rotary speed and direction
