Balluff ultrasonic sensor DBK+4/CDD/O/M18 E-K7K2/S-K2

balluff ultrasonic sensor DBK+4/CDD/O/M18 E-K7K2/S-K2

balluff Balluff dbk+4 series ultrasonic double-sheet detector

dbk+4 Main features:

● Optional self-learning, e.g., for solar silicon wafers adhered together by water

● The top sensing head is at a 90° angle for special installation conditions

● Models with an external M18 amplifier are available, saving installation space

● Compact M12 threaded sleeve transmitter and receiver for tight installation spaces

● 3 control inputs for external sensitivity selection, triggering, and self-learning based on the material being measured

● Basic features:  

● Reliable detection of single and double sheets

● No self-learning required (plug-and-play), maximum convenience for customers, easy to use

● Double-sheet and missing-sheet outputs for displaying double-sheet, single-sheet, and missing-sheet status

● Operating distance between transmitter and receiver from 20-60mm, selectable, offering great flexibility

● Optional trigger mode for applications similar to warehouse processes

● Can be parameterized via connection control, offering great flexibility
 

Functional principle  
An ultra-high-frequency ultrasonic transmitter emits an ultrasonic beam from below the sheet. The sound waves cause the sheet to vibrate, which also generates a very small sound wave on the other side of the sheet, received by the ultrasonic receiver.

When the signal passes through two layers of sheets (double-sheet), it becomes very weak and cannot reach the receiver. dbk+4 can detect missing sheets, single sheets, and double sheets.
 

Application range of dbk+4:
 
● Paper printing machines
● Assembly machines
● Folding machines
● Packaging machinery
● Solar cell and silicon wafer manufacturing industry
● Labeling
