The OPB608 non-focused reflective switches are available with IR LED, IR VCSEL, or visible light emitters to provide a variety of detection ranges for different materials. The 890-nm IR LED-based ...

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 ...

I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

Vishay’s VCNL4100 is an IR proximity sensor that works up to 1m, and includes an ambient light sensor. Inside, it combines an infra-red (940nm) emitter, photo detectors for proximity and ambient light ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...
