Proximity Detector with Adjustable Range

The Ngineering Proximity Detector with Adjustable Range uses transmitter and receiver sensors with a very narrow 15 degree detection angle to locate object position and movement. The output from these sensors is processed through Ngineering's proprietary electronics to compare the signal to an adjustable precision reference voltage. A knob is provided for this adjustment. This provides precision adjustment of detector range to within 1-1/2 inch accuracy in distance. An LED indicator establishes a visual "trigger" position for detection distance setup. Once the distance is set, objects from that distance down to 3 inches will be detected. Objects beyond that setting will be ignored. A small slide switch is provided for selection of two basic range modes: 3 inches to 3 feet, and 3 inches to 10 feet. A sturdy PVC mounting bracket is provided for easy installation of the proximity detector.
