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 ...

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: ...

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 ...

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).

These light barriers create a closed light beam between the sensor and machine part. A separate reflector is unnecessary, reducing operating costs and increasing process safety. SmartReflect light ...

The Optoelectronics group of Vishay Intertechnology, Inc. has introduced a new reflective optical sensor with a lower profile than previous generation devices. The Vishay Semiconductors VCNT2025X01 ...

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 ...

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 ...

Würth Elektronik has revealed two reflective optical sensors. These are simple devices, with an infra-red emitter and a photo-transistor, both facing upwards, but work at an unusual wavelength. “These ...

An 880-nm AlGaAs infrared emitter (IRED) and a NPN open-collector photo device (photo-IC) are mounted on a custom, four-leaded TO-72 header to make up the CL1700 Reflective Object Sensor. The IRED ...

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 ...
