The functional principle of an incremental rotary encoder is fairly straightforward. High resolution and accuracy along with excellent dynamic response. MASSO contactless optical quadrature encoders are based on a non-mechanical design. Optical encoders affix an opaque mask to the motor rotor; as the rotor changes position, the pattern of light passing through the mask changes. On the scale, there is a sensor, it can read the scale and determine its position. Optical absolute rotary encoders are constructed with either glass or plastic material disc with transparent and opaque surface areas to allow the light source and photodetector to detect optical patterns. POSITAL's IXARC optical absolute rotary encoders use highly integrated Opto-ASICs, providing a resolution up to 16 bits (65,536 steps) per turn. The yield of an outright encoder demonstrates the current shaft position . Generally, this encoder includes a disk, spaced evenly with contact zones. Optical Rotary Encoder E6B2-CWZ6C . The graphic below outlines the basic construction of an optical incremental rotary encoder. Periodically, these tracks have an opening, called a window. Optical rotary encoders are by nature of their manufacture are much more expensive than the mechanical (conductive) rotary encoders previously shown. A A. The encoder provides feedback based on the interruption of light. The most popular type of encoder is the optical encoder. Features: 1. There are 3 major types of magnetic encoders: Magnetic Gear Tooth Sensor or . Rotary encoders translate the mechanical rotational motion of an object such as a motor shaft into an electronic signal. The miniature rotary sensor fits into tight spaces and has wide alignment tolerances for easy installation. 1.
