Raster Decoder For 180LPI-15*1500MM Encoder Tape
How does it work?
The transmitter aims at the target and emits a beam of light, which generally comes from semiconductor light sources, light-emitting diodes (leds), laser diodes and infrared emitting diodes. The beam is emitted without interruption, or the pulse width varies. The receiver is composed of photodiode, phototriode and photocell. In front of the receiver, optical elements such as a lens and an aperture are installed. Behind it is the detection circuit, which filters out the effective signal and applies the signal.
How to locate?
There are many vertical bars on the grating, and it locates by counting the position of the bars.
Function: It is to read the raster data, the main function of the raster is positioning, the decoder reads the data to the small car plate, the small car plate and then control the ink.
Features
—Use thick cables to connect them tightly
—High precision, fast response
—Automation and digitalization
Photoelectric sensors are controlled by converting changes in light intensity into changes in electrical signals.
Photoelectric sensor in general, there are three parts, they are divided into: transmitter, receiver and detection circuit.
