I was wondering if any could tell me how to take a commercial motion detector and convert it to run off of 9 or 12 VDC. Thank you

I think you are talking about Infra Red motion detectors.Most of them are 4.5V. You can use a voltage regulator 7805 IC(5VDC Output) after your 12 or 9VDC supply. In case your detector requires a different supply voltage simply choose a 78XX(XX=Volt

Barry: We use motion detectors: * In our product packaging to determine if the shipper has drop kicked the box down the stairs. * Along our conveyors in production to sense a "line full" These are far different applications and probably far diffe

Hello Does somebody of you have some experiences with ultrasonic detectors in SMT-Production? Is it possible to test quality of solder joints by using a ultrasonic detector similar to non destrucitve crack inspection tests? Is there a manufacturer fo

Thank you for the links. I didn't know that there are companys that build test systems for ultrasonic inspection. My idea was to use a ultrasonic detector similar to crack inspection, for example to detect if the cooling pad is melted, or a solder jo

We have had a few circuit cards come off the end of the oven and get damaged. Most cards have no problem sliding onto a ramp, but a few don't fare so lucky. Has anyone had any luck using a motion detector with an audible alert? I tried google, but I

We are tring to locate a 9 segment LED & dectector array. It is used in a coin reader to measure the diameter of a coin. Any help in locating such an array will be highly appreciated.

We used a photo-optic sensor powered off the conveyor after the oven that is tied to a relay that trips when a board is seen at the sensor which causes a buzzer to go off. Very simple to make. Good luck.

It won't work. An acoustic signal can't punch through a BGA. The signals reflect at every interface. So, it works for flip chip, but there are too many interfaces in CSP and BGA. Equipment, Inspection, Acoustic microscope * MicroPhotonics * Sonos

Many years ago... my old engineer used a very simple unit bought at Radio Shack. It was a device that they use in door ways to announce someone was entering the store. It used a beam of light and when the board broke that beam, a bell/ring/noise wou
