Projected beam detector
Webdesign is much quicker than a dual-ended projected beam detector. Alignment is easily accomplished with an optical sight and a two-digit signal strength meter incorporated into the beam detector. Listed for operation from –22°F to 131°F, the FSB-200 and FSB-200S are usable in open area applications where temperature extremes exceed the design Webended projected beam detector.
