Solar Cells Transfer Equipment

Sense passing of cassettes
B5W-LB

Usage

  • ・Detect passing of the cassette on a transfer equipment for solar cells.

Issues & Requests

  • ・Want to stably sense colored solar cell cassettes.
  • ・Need a sensor allowing variations in the cassette’s position depending on the conveyor.

(Issues)
Color coding of solar cell cassettes varies depending on the equipment user.
General reflective sensors may not be able to stably sense any objects of low reflectance such as colored in black. 

Solution

  • ・Adopted model:
    Light convergent reflective sensor B5W-LB2112-1
  • ・This sensor is optically designed to detect objects with low reflectivity, such as transparent plastic and black. Therefore, it is useful for detecting cassettes of various colors.
  • ・Since the sensing range for various objects is wide, the positional variation of the cassette is also acceptable to some extent. See the fugues below.

For details, refer to B5W-LB Series: Light Convergent Reflective Sensor User’s Manual.

  • Distance Characteristics for
    Various Reflective Objects
  • Receiver Output-Sensing Distance Characteristics

*The possibility of detecting the object varies depending on the sensing object or how to install the sensor.
Be sure to conduct sufficient evaluation using the actual devices before staring practical use.
