What is a Rotary Encoder and Why Use Them?

Understanding Rotary Encoders

A rotary encoder is an electromechanical device that converts the angular position or motion of a shaft or axle to an analog or digital signal. It helps determine position, speed, and direction in various industrial and mechanical systems. Rotary encoders are essential components in automation, robotics, and machinery that require precise motion control.

Types of Encoders

Our two primary classifications of encoders are Incremental Encoders and Absolute Encoders:

Incremental Encoders

Shaft Encoders (Solid Shaft): These encoders have a solid shaft that attaches directly to the rotating component. They are ideal for straightforward, robust mounting in machines with aligned shaft designs.

Hollow Shaft Encoders: These have a hollow center that fits over a shaft, making installation easier and allowing for compact, inline setups. They reduce coupling complexity and can accommodate axial and radial misalignments.

Wheeled Encoders: Often used for linear measurement, these encoders integrate a measuring wheel that contacts the surface, converting linear motion into rotational data. They are ideal for conveyor belts, textile machines, and other applications involving continuous surface tracking.

Absolute Encoders

Absolute Encoders: These provide a unique digital code for each shaft position, maintaining position data even after power loss. Absolute encoders are ideal for applications requiring precise and consistent position tracking.

BlueCoder

Tri-Tronics' new optical incremental encoder that takes advantage of the benefits of short wavelength light. Blue light reduces diffraction effects as it interacts with the slots of a code disk and also takes advantage of modern semiconductor processes with small shallow structures. Coupled with the excellent temperature-stability of blue LEDs, BlueCoder resolution, accuracy and stability is unmatched.

BlueCoder Shaft Encoders

directly couple to a device shaft and generate a specific pulse output for each revolution. Select from a variety body sizes and styles. Multiple face mounting options and connectors are available.

BlueCoder Wheeled Encoders

Directly riding on moving material using a wheel. Wheel tread has a high coefficient of friction and a very low starting torque resulting in virtually no slippage on the belt. Wheels are designed to a specific circumference and are precision ground to exacting tolerances and NIST standards; versus low tolerance generic rollers whose circumference is not matched to the measuring application. Select from a variety of body sizes, single/dual wheel construction and wheel diameters and types.
