An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

The CLI700 reflective object sensor consists of an 880-nm aluminum-gallium-arsenide (AlGaAs) infrared emitter and an npn, buffered, open-collector IC. Both are mounted on a custom, four-leaded TO-72 ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...
