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 ...

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 ...

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 ...

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, ...

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 ...

Leuze has introduced a broad range of stainless steel optical detectors for the food industry. “The devices are designed for reliable operation in wet areas and during intensive cleaning processes and ...

Precision sensor specialist Micro-Epsilon has supplied 600 eddy current sensors to the Chinese Academy of Science for use on the LAMOST (Large sky Area Multi-Object fibre Spectroscopic Telescope), the ...
