Incremental optical encoders are what to consider when selecting according to the signal transmissio

When selecting an incremental optical encoder, the signal transmission distance needs to be considered, because the distance of the signal transmission will affect the performance and stability of the encoder. Here are a few things to consider:

1.Signal transmission distance: The signal transmission distance of incremental optical encoder is limited, generally within tens of meters. Therefore, it is necessary to select the appropriate encoder according to the signal transmission distance of the actual application scenario.

2.Signal transmission mode: There are two signal transmission modes of incremental optical encoder, one is differential signal transmission, and the other is single-ended signal transmission.

Differential signal transmission can effectively suppress interference, but the transmission distance is shorter; Single-ended signals are transmitted over long distances, but are susceptible to interference.

3.Signal transmission speed: The signal transmission speed of incremental optical encoders is also a factor to consider. If the signal transmission speed is too fast, the signal will be distorted or lost, which will affect the measurement accuracy and stability of the encoder.

4.Environmental interference: Environmental interference is also a factor to consider in the case of long signal transmission distances. For example, electromagnetic interference, temperature changes, etc., can affect the stability of signal transmission.

To sum up, it is necessary to consider factors such as signal transmission distance, signal transmission mode, signal transmission speed and environmental interference when selecting incremental optical encoders to ensure their performance and stability.

The gaze wanders in the pure light and clouds of the sky, and the longing is chosen to avoid answering, and the autumn soup leaked from the treetops is mixed with an ambiguous attitude, and the complex admiration on the quiet water. Walking a little closer, he wanted to express the pleasant emotions in Oak Qinda's heart but was vague, like looking at the clouds in the sky in a daze, saying that the frank appearance was not an airplane, and after smiling emotionally, he asked about what he had forgotten.

The relative optical encoder is composed of a photoelectric detector, a grating disk, a signal processing circuit and an output interface. A photodetector is a device that combines a photoelectric converter and a signal processing circuit to detect the grating stripes on the grating disc and convert them into electrical signals. The grating disc is composed of alternating transparent and opaque fringes, and when the light hits the dissolution on the grating disc, the transparent and opaque fringes produce alternating light spots, which are converted into electrical signals by the photodetector.

The signal processing circuit is used to process the electrical signal output by the photodetector and convert it into a pulse signal for easy counting and measurement. The output interface outputs the processed pulse signal to external devices, such as PLCs, computers, etc. The advantages of relative photoelectric encoders are high measurement accuracy, high resolution, good reliability, strong anti-interference ability, and long service life.

It is widely used in machine tools, automated production lines, and other fields to measure the position, speed, acceleration and other parameters of objects. Extraneous extension: The difference between relative optical encoder and absolute optical encoder is that relative optical encoder can only measure the relative displacement of the object, but cannot determine the absolute position of the object; Absolute optical encoders, on the other hand, can directly measure the absolute position of an object.

Summary. The basic components of a relative optical encoder include: light source, reflection enhancer, detector, transmitter and receiver.

Light source: It is the source of the light that illuminates it, and can be used as a light source using a diode laser, a white light protrusion lamp, or an LED. Reflection Enhancer:

It is a small reflective element that reflects light back to the emitting source at both the transmitter and receiver ends. Detector: The detector is used to detect the light reflected from the transmitter to obtain the encoded signal.

Reflected light can be detected using an integrated photoelectric component such as PhotoTransistor or Photocell. Emitter: Used to emit light to send a beam into the magnetic ring to obtain a measurement signal.

Receiver: The receiver is used to receive the light emitted by the transmitter to obtain the encoded signal at the other end.

It is the source of light that irradiates the head, and can be used as a light source using a diode laser, a white light protrusion lamp, or an LED. Reflection Enhancer: It is a small inverted trigger element that reflects light back to the emitting source at both the transmitter and receiver ends.

Detector: The detector is used to detect the light reflected from the transmitter to obtain the encoded signal. Reflected light can be detected using an integrated photoelectric component such as PhotoTransistor or Photocell.

Emitter: Used to emit light to send a beam into the magnetic ring to obtain a measurement signal. Receiver:

The receiver is used to receive the light emitted by the transmitter and thus obtain the encoded signal at the other end.
