[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 ...

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 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 ...

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 ...

Offered as a direct form, fit and function for the Optek OPR5005 sensor, the 67070 reflective sensor detects the proximity or motion of diffuse reflective surfaces. The component combines a silicon ...

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 ...

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 ...

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

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 ...
