1. Resolver A resolver is a type of rotary electrical transformer used for measuring degrees of rotation. A resolver is an electromagnetic device that functions as a rotating transformer to measure the angular position and speed of a rotating shaft. Unlike digital encoders, resolvers are analog and are known for their exceptional durability in extreme operating conditions, such as high temperatures, shock, and vibration.

2. What is an Optical Encoder ? An optical encoder is a motion sensing device that utilizes light to convert mechanical motion into electrical pulse signals. It provides accurate position information in industrial applications like robotics, CNC machines, and motor control systems. Accurate motion details, like speed, are achieved sensors that give slightly different signals. They offer high accuracy, resolution, and reliability, and can operate in harsh environments.

3. Masked Optical Rotary Encoders Masked optical encoders have four components: a light source, a sensor, a movable disk, and a fixed mask. The LED light shines through one side of the optical shaft encoder, and the encoder disk has a series of tracks on it. The mask has a corresponding track for every track on the disk of the optical encoder. The tracks of the mask have many small perforations, called windows. The windows that are open versus closed during rotation determine the position of the optical shaft encoder.

4. Phased- Array Optical Rotary Encoders Phased-array optical encoders are even more reliable than masked optical encoders. They use multiple signal outputs to average together to create a single signal that is delivered by the engine. These multiple signals that are used by an optical shaft encoder are called the array. y using averages instead of a single reading, phased-array optical encoders have much more stable signals. This means they can be used in less stable environments, such as mining or heavy manufacturing, where vibrations or shock could affect a traditional masked optical shaft encoder. They require less precision during installation than traditional masked optical encoders.

5. What are magnetic encoders? Magnetic encoders are a type of rotary encoder that use sensors to identify changes in magnetic fields from a rotating magnetized wheel or ring. There are 3 major components in a magnetic encoder: Sensing Circuit A rotating wheel or ring A series of magnetic poles around the circumference of the wheel or ring As the wheel or ring spins past the magnetic sensor, the poles cause a predictable response in the sensor based on the strength of the magnetic field. The magnetic response is fed through a signal conditioning electrical circuit and output as a digital signal to the controlling device.
