Subminiature Thru-Beam Pairs T&C Industrial Controls
MEK80-2100
The MEK 80-2100 emitters and receivers are enclosed in anodized aluminum housings built to withstand shock and vibration. Both emitter (anodized red) and receiver (anodized black) are spectrally matched to provide optimum performance. This thru-beam pair is offered in three different mounting configurations and is our smallest thru-beam, making it ideally suited for operation in very confined areas. The emitter can be ordered with either visible or infrared lightsource. Some typical applications of this thru-beam pair include small parts detection, counting and edge control.
