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 ...

[Sebastian Steppeler] has been hard at work on his optical sensors for an electric piano. When we looked in on the project back in October he was testing reflective sensors to increase responsiveness ...

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 ...

When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

Here is the circuit of a little label sensor ideal for detecting labels on bottles. The circuit offers a peak sensing distance of 2.5 mm (operating range 0.2 mm to 15 mm) backed up by the proven ...

Kyoto Semiconductor Co., Ltd. (President and CEO: Yoshihisa Shinya, Headquarters: Shimotsuke-shi, Tochigi, Japan), a leader in optical device solutions with Japanese quality manufacturing based on ...

TT Electronics has announced its OPB735 series Reflective Object Sensors for challenging industrial automation and safety applications. This reflective sensor features hermetically sealed components ...

Marktech Optoelectronics has announced the expansion of its surface-mount family of SWIR reflective sensors. The sensors are suitable for position sensing and detection applications, including card, ...

Capable of integrating infrared, visible light, or VSCEL sensing capabilities in a single package, the OPB608 series reflective sensors can detect objects at distances up to 2". Each component in the ...

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 ...
