These are items that are still in new and unused condition that have been on the shelf or in storage for a number of years. Most of my items are in the original factory boxes or cases. Some of these boxes show a good bit of wear and tear from storage time and handling. I try to add to my store listings all the time. Please keep in touch. Mike Hi Mike, I was finally able to get the sensor to work with my system and find a scope to measure the output. I measured it at 5V peak-to-peak. Thanks again.
