The Biggest Challenges in Detecting Transparent Objects
Transmission Rate of Transparent Objects
Solution:
- Retro-reflex sensors for transparent objects, laser distance sensors ToF and fork sensors enable reliable detection even in fast applications due to their high sensitivity and switching frequency
- Ultrasonic distance sensors and ultrasonic fork sensors for label detection detect the object regardless of transparency or color
Resistance to Contamination
Solution:
- Thanks to the dynamic readjustment of the switching threshold, taught-in retro-reflex sensors for transparent objects and reflex light barriers continuously adapt to varying ambient conditions
- For applications in particularly dusty environments, ultrasonic distance sensors are suitable.
Interference Effects with Irregularly Shaped Objects
Solution:
- Retro-reflex sensors for transparent objects are suitable for glossy surfaces due to their single-lens optics
- The sonic cone of ultrasonic distance sensors detects large areas and also reliably detects irregular shapes
