It is an อินฟราเรด sensing photoeleCtriC ผลิตภัณฑ์, whiCh is คอมposed of an อินฟราเรด transmitter tube and an อินฟราเรด reCeiver tube. The slot width is It determines the strength of the induCtion reCeiving model and the DIstanCe of the reCeived signal. Light is used as the meDIum, and the อินฟราเรด light between the luminous body and the light reCeiving body is reCeived and Converted to deteCt the position of the objeCt. The trough photoeleCtriC สวิตช์ is also non-ContaCt like the proximity สวิตช์. It is less restriCted by the deteCtion objeCt and has a ยาว deteCtion DIstanCe. It Can deteCt ยาว DIstanCes (สิบเมตร) with สูง deteCtion aCCuraCy and Can deteCt small objeCts. The appliCation is very wide.
