Light and sound are two natural phenomena which let every living being recognise their environment without physical contact and over widely varying distances. Likewise, industrial processes require reliable information. SICK’s ultrasonic sensors UM 30 and UM 18 detect objects and measure distances with high accuracy.

Ultrasonic proximity switch

• One or two binary switching outputs, or analogue output
• Ultrasonic, non-contact detection and distance measurement of objects
• Highly accurate measurements
• Large scanning ranges
• Detection of transparent objects and fluids
• Highly available,even under Unfavourable environments
• Binary of analogue output

Ultrasonic double-sheet detection

• Double-sheet check for film, paper, corrugated cardboard and fine metal sheet
• Automatic adjustment
• Alignment and Teach-in unnecessary
• Compact design
• Plug and play
• 2 PNP outputs for double- and mis-fed-sheets
