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).

1300-1650nm light source and photodetector integrated into one package SHIMOTSUKE-SHI, Japan--(BUSINESS WIRE)--Kyoto Semiconductor Co., Ltd. (President and CEO: Yoshihisa Shinya, Headquarters: ...

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 ...

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 ...

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 ...

The Optoelectronics group of Vishay Intertechnology has introduced a new AEC-Q101 qualified reflective optical sensor for automotive, smart home, industrial, and office applications. Offering a lower ...

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 ...

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 ...

Once you have a track and a kart to race on it, what’s missing? A lap counter that can give your lap times in hardcopy, obviously! That’s what led [the_anykey] to create the Arduino-based Lap Timer to ...
