U-GAGE S18U Series—Discrete
Overview
- Offers 10 to 30V dc supply voltage with bipolar NPN or PNP output
- Senses from 30 to 300 mm
- Features minimal dead zone and eliminates dead zone if used in retrosonic mode
- Ideal for material handling and packaged goods applications, such as bottling or liquid level detection and control for small containers
- Available in straight or right-angle versions with a wide variety of mounting hardware for enhance sensing versatility
- Offers programmable background suppression
- Compensates for temperature, for greatest sensing accuracy
- Simplifies setup with push-button and remote TEACH-mode programming
- Shows status during setup and operation, using highly visible LEDs indicators
