Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get adjusted ...

The CLI700 reflective object sensor consists of an 880-nm aluminum-gallium-arsenide (AlGaAs) infrared emitter and an npn, buffered, open-collector IC. Both are mounted on a custom, four-leaded TO-72 ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Everyone is familiar with pinwheels, and few of us haven’t crafted one from a square of paper, a stick, and a pin. Pinwheels are pretty optimized from a design standpoint, and are so cheap and easy to ...

The reflective properties of plastic make it a notorious offender in this regard. The problem even extends to those objects covered in shrink wrap. Polarizing filters help block false readings from ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

Company Announcement - The Leuze RK46C-VarOS retro-reflective photoelectric sensor is capable of detecting objects over an operating range of 0.4 to 5.2 metres, with a light band width of 45 to 50 mm.

Hamamatsu Photonics has recently developed a new reflective sensor named P13567-02CT. The sensor is designed to work with near-infrared/proximity types and is packaged in a compact size. It contains ...

Taiwan Biophotonic Co., a leading provider of non-invasive vital signs sensing solutions, today announced the release of its DOE reflective sensor for fingerless wrist-worn pulse oximeters, which ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
