Detects Presence of LCD Substrates in High-temperature Environments

Case Number 40

last update: April 13, 2015

This application uses a Through-beam Fiber Sensor that is heat-resistant to 200°C. 


Install heat-resistant Through-beam Fiber Sensor with a convergent-reflective arrangement. This setting is hardly affected by the background, which enables precisely detecting the presence of LCD substrates.

Know-How

Convergent-reflective sensors or distance-settable sensors that can be used in high-temperature environments were not available. A diffuse-reflective sensor also detected a hotplate in the background, which prevented stable detection of only the LCD substrates.

Benefit / Efficiency

In this application, you can use a heat-resistant Through-beam Fiber Sensor with a convergent-reflective arrangement. You can flexibly apply the characteristic that resists the effects of the background to meet the conditions of your facilities.

Also, the large spot diameter ensures stable detection of LCD substrates that could fluctuate in position in the production process.
