Overview
U-GAGE® T18U Series Sensor is an opposed mode ultrasonic emitter/receiver pair. It uses an advanced built-in microprocessor to analyze the received ultrasonic signal and control an indicator LED located on the back of the receiver. The receiver LED flashes at a rate proportional to the received sonic signal strength. This indicator greatly simplifies sensor alignment and alerts personnel to marginal sensing conditions because of gradual misalignment or environmental factors. The receiver is precisely tuned to the ultrasonic emitter, making this sensor pair highly immune to both sonic and electrical ambient noise.

Ultrasonic Opposed Mode Sensor Pairs with Dual Sensing Ranges

• Dual range/dual resolution opposed mode ultrasonic sensors; ideal for reliable sensing of clear objects or materials
• Rugged design for use in demanding environments: rated NEMA 6P (IEC IP67), wide-operating temperature range of −40 °C to +70 °C (−40 °F to +158 °F)
• Alignment indicator flashes at a rate proportional to the received signal strength
• Highly immune to ambient sonic and electrical noise
• Popular T-style right-angle sensor package with 18 mm threaded mounting hub; cabled or quick disconnect models
• 12 to 30 V dc operation; choose receivers with either NPN (sinking) or PNP (sourcing) output; outputs are short-circuit protected
