A Capacitive Rotary Encoder Based on Quadrature

Working Principle: Capacitive encoders measure displacement by detecting changes in capacitance between the read head and the scale. The encoder’s electrode patterns interact to form a capacitive network, which is converted into displacement signals. The capacitive encoder models further offer users compact packages, current draw as low as 8 mA at 5 V, and operating temperature ranges from -40 to +125°C.

Linear Encoders can be “Absolute” or “Incremental” measurements. A Rotary Encoder collects data and provides feedback based on the rotation of an object or in other words, a rotating device.

Capacitive rotary encoders are sensors that detect rotational positions by measuring changes in capacitance. They typically consist of a fixed capacitance array, a rotating capacitance disc, and reading circuits.

An Absolute Capacitive Rotary Encoder (ACRE) constructed out of two simple PCB’s. After doing lots and lots of research (a few years back) I figured out how to replicate the technology used in electronic calipers. Two weeks back I decided to create an opensource angle sensor using this technology and cheap parts.

Our rotary encoders equip users with a range of resolutions, shaft length and bore diameters, and output signal types. Highlighting this product group is our groundbreaking AMT encoder line based on capacitive technology, delivering Rotational A rotational capacitive encoder design is very much like the linear one, except everything is drawn on polar co-ordinate system rather In comparison with the optical and electromagnetic encoder, the capacitive encoder has some significant advantages [4, 5] such as simple in design and cost effective. Also, the resistance of capacitive encoder against mechanical vibration and misalignment is better than the optical encoders.

Capacitive linear encoders function based on changes in capacitance due to motion, while optical linear encoders use light-based sensors to detect position. Though both serve similar purposes, capacitive linear encoders have gained significant popularity due to their advantages over optical encoders, making them the preferred choice in various industries. Capacitive Capacitive linear encoders work by sensing the capacitance between a reader and scale. Typical applications are digital calipers. One of the disadvantages is the sensitivity to uneven dirt, which can locally change the relative permittivity.
