Speed Of Incremental Encoder

The incremental encoder is the sensor which outputs the angular displacement in pulse form. Its code plate is in the circle of 360° subdivided a number of equal lines, the more lines, the higher the resolution. General Increment encoder has three code path, namely a, B, Z Road. The phase difference of A and B is 90°, which is used to distinguish the rotational direction; Z is used to record the number of cycles the Delta encoder has turned.Incremental Encoder The incremental photoelectric encoder mainly consists of a light source, a code plate, a detection grating, a photoelectric detection device and a conversion circuit. The characteristic is that each output pulse signal corresponds to an increment displacement, it can produce a pulse signal with the increment of displacement equivalent, and the signal is displayed or controlled by the upper instrument or computer. The increment encoder is mainly used for measuring speed, acceleration, rotation direction and angle. Widely used in walking machinery, CNC machine tools, elevators, servo motors, flowmeter, textile machinery, metallurgical machinery, injection molding machinery, printing and packaging machinery, automation instrumentation and other industrial automation and measurement field.Incremental Encoder When an incremental encoder is moved, the encoder produces a binary pulse flow proportional to the axis rotation speed (Rotary encoder) or motion distance (linear encoder). When the optical encoder is used, the specific pattern of the encoder or the linear band which is placed between the LED light source and the light sensor can alternately guide or block the beam, resulting in an analog signal, and the extra circuit (usually the onboard ASIC) converts the analog signal to a square wave. A magnetic encoder can operate in a variety of mechanisms, but it rotates a magnetic field, resulting in a voltage pulse or a change in the resistance that can be converted to a pulse.Incremental Encoder

A single channel incremental encoder can only output a single pulse stream, thus providing only limited information. Depending on the resolution of the encoder, i.e., the number of pulses per lap of the rotary encoder or the motion distance of the linear encoder (mm/inch), the external electronic device can count the pulses and calculate the velocity or the orbital offset relative to a reference coordinate (starting position), thereby determining the encoder position. Single channel design provides an excellent solution for applications such as one-way conveyor systems.Incremental Encoder
