An Infrared Photoelectric Sensor With Adjustable Sensitivity For Inkjet Printer

1.inkjet printer sensor is a kind of sensor that uses infrared rays to process data. It has the advantages of high sensitivity and can control the operation of the driving device.
2.infrared photoelectric inkjet printer sensor are often used in contact-free temperature measurement, gas composition analysis and nondestructive flaw detection, and are widely used in medicine, military, space technology and environmental engineering. For example, the infrared sensor is used to measure the temperature of the human body surface from a long distance, and the temperature abnormality can be found.

The transmitter aims at the target to emit a beam, which is generally derived from a semiconductor light source, light emitting diode(LED), laser diode and infrared emitting diode. The beam was fired uninterrupted, or the pulse width was changed. The receiver is composed of photodiode, photoelectric triode and photoelectric cell. At the front of the receiver, there are optical elements such as lenses and apertures. Behind it is the detection circuit, which can filter out the effective signal and apply the signal. In addition, there are emission plate and optical fiber in the structural element of photoelectric switch.

The triangular reflector plate is a solid structure launcher. It is composed of small triangular cone reflective materials, which can make the beam accurately return from the reflector plate, and has practical significance. It can change the emission Angle from 0 to 25 to the optical axis, so that the beam is almost from an emission line, after reflection, or back from the reflected ray.
