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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
