U-GAGE T18U Ultrasonic Sensors

Overview

  • Uses high-frequency acoustic emitter and tuned receiver for accurate opposed-mode ultrasonic sensing
  • Housed in T-style right-angle housing with 18 mm threaded nose
  • Offers response time of 2 milliseconds and range of 600 mm for longer-range applications
  • Offers ultra-fast response time of 1 millisecond with a range of 300 mm for high-speed applications such as counting
  • Offers 12 to 30V dc supply voltage with NPN or PNP output, depending on model
  • Reliably detects clear material such as glass
  • Highly immune to electrical and acoustic noise
  • Operates at temperatures from -40° to 70° C
  • Includes signal strength indicator to make alignment easy
