The Ultrasonic Range Detector will close a relay when it senses an object within an adjustable distance. The relay will be released after an adjustable delay. Screwdriver adjustments determine range and delay. A jumper selects low or high range.
Options:
Jumper installed – Low Range: 5 – 40 centimeters, 0.2 to 10 seconds release delay
Jumper removed – High Range: 5 – 400 centimeters, 1 to 100 seconds release delay
Range and delay adjustments are pseudo-log scale with highest resolution at the low end of the scale.
Supply voltage (+V) from 7 to 20VAC or 10 to 24VDC.
The Ultrasonic Range Detector is presently available in kit form or 2 assembled versions. The sensor can be
hard mounted to the PCB or it can be connected through a 8″ ribbon cable, as shown.
