"Sick UM18-20012 Overview
Ultrasonic Sensor UM18-20012 Sender/receiver 2 switching outputs PNP

Sick UM18-20012 Description
Double-sheet detection of foils, metal sheets and thin corrugated cardboard 
Operational area 40 mm +/- 3 mm 
Automatic adjustment, plug and play operation 
Color- independent detection 
Two PNP outputs for double and miss-fed sheets 
Your benefits

Increased quality and productivity through reliable double sheet detection 
Fast commissioning since sensor does not require calibration or teaching 
Reliable detection of transparent foils, various paper types and thin metal sheets provide application flexibility
