Ultrasonic Sensor XL-MaxSonar -WRC1-Water Proof
The XL-MaxSonar-WR sensor provides very short to long-range detection and ranging, in a compact, robust PVC housing, designed to meet IP67 water intrusion, and matches standard electrical 3/4" PCV pipe fittings. The sensor puts 1/2 watt of peak power into the efficient transformer driving ...
Optomax Digital Liquid Level Sensor
The Optomax is an optical liquid level sensor that detects the presence or absence of almost any liquid — oil or water based. Inside the polysulfone housing, an infrared LED and matching phototransistor work together: when dry, the IR light reflects internally back to the sensor; when the tip is ...
