Distance-measuring reflection photo sensor




We want to detect such P. C. board!

Feature

  • Doesn't detect background
  • Stable detection even black P.C. Board
  • Sharp detection characteristics
    This sensor doesn't detect background because of distance-measuring reflection type.
  • Detection of notch or hole
    This sensor has oval detection area(19mm×2mm*) by applying non-spherical surface toric lens.
  • This value is for PD4-35RT/35RS. It is 24mm×2mm for PD4-45RT/45RS.

Complete functions

1. Detecting PC board with hole and notch

2. Doesn't detect background

[Usual sensor]

[PD4]

 

3. Stable detecting for black PC board

Detecting principle

It calculates the distance operation with light-receiving level ratio between near and far light-receiving photo diode(PD) in accordance with detecting distance.

Applications

P.C. board detection

CD detection

Round objects detection without background influence

(1) Round objects detection

(2) Detecting system without background Influence

[Usual sensor]

[PD4]

Screw existence detection

[Usual sensor]

[PD4]


Detection with same colors and background at short distance
For example, it is possible to detect even if detecting objects is close to background and is the same color.

(1) Seal detection
