* Minimum Object Detection: Smallest d i ameter rod that can be detected when passed slowly through sens i ng beamNOTE: M i n i mum object detect i on i s measured m i dway between the em i tter and rece i ver . For best results, objects to be detected should be placed i n the m i dway pos i t i on when poss i ble . The m i n i mum object detect i on s i ze may i ncrease i f the object i s very close to the rece i ver s i de .** Hysteresis: D i stance an object must move to toggle between output OFF and output ON cond i t i ons *** Repeatability: Var i at i on i n sw i tch i ng d i stance for a standard target at controlled sens i ng cond i t i ons More i nformat i on onl i ne at
