The ENS22S001 is a high-quality mechanical rotary encoder from Cooka, offering 64 pulses per revolution with standard quadrature (A/B) output. Fully sealed and rated IP65, it's built for reliable operation in harsh environments and extended-life applications.
With low indent detents, this encoder provides minimal turning friction and subtle tactile feedback — ideal for user interfaces, instrumentation panels, and precision control. It features a 1/4-inch shaft compatible with a wide range of knobs, and supports both 3.3V and 5V operation for easy integration with most microcontrollers.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
