Sick UM18-20014 Overview
Ultrasonic sensor double sheet detection UM18-20014 Sender / Receiver 2 switching outputs NPN
Sick UM18-20014 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
- 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
