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 ...

The EQ-34-PN-J is a photoelectric sensor with adjustable range reflective and PNP open collector by Panasonic. The device has a minimum operating supply voltage of 10 VDC. The device hardly gets ...

Promising an enhanced sensing range in space-constrained applications, the OPB733TR reflective object sensor measures 0.3" x 0.16" with a PCB-mounted profile of 0.114". The component incorporates a ...

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 ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

Operating at distances from 2 mm to 40 mm, the 6 mm x 3.76 mm x 3.9 mm, surface-mount TCND5000 reflective optical sensor integrates an IR emitter and PIN photodiode in a single package. The device is ...

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 ...

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.

[Arao] wanted to measure the RPM of a spinning wheel using parts that he could scavenge from his junk box. A bit of thought led him to build a reflective sensor which can measure the spinning of a ...
