Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric ...

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 ...

CAMBRIDGE, UK — The OPB733TR miniature reflective sensor from Optek combines a 7.6×4.06 mm footprint with lensed optics for enhanced sensing range in space-constrained applications. The reflective ...

Reflective systems have the beam transmitter and receiver in the same housing (a transceiver), with a reflective plate on the opposite wall. This can still be up to 100m away, and the plate is ...

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 ...
