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 ...

A reflective optosensor counts revolutions as the turbine spins in an HVAC duct, and with a little calibration the rig produces good results. The limitations are obvious: duct turbulence ...

New optical sensors feature enhanced detection capabilities and faster commissioning with innovative Power PinPoint LED ...
