SUNX光电传感器PM-R44 光电传感器的输出特性是指在一定的发光电流IF下,光敏管所加偏置电压VCE与输出电流IC之间的关系,当IF=0时,发光二极管不发光,此时的光敏晶体管集电极输出电流称为暗电流,一般很小。当IF>0时,在一定的IF作用下,所对应的IC基本上与VCE无关。IC与IF之间的变化成线性关系,用半导体管特性图示仪测出的光电耦合器的输出特性与普通晶体三极管输出特性相似。其测试连线如图2,图中D、C、E三根线分别对应B、C、E极,接在仪器插座上。 光电传感器的测试 PM-T44,PM-K44,PM-L44,PM-Y44,PM-R44,PM-L24,PM-T24,PM-F24,PM-F44,PM-Y24,PM-R24,PM-T44P,PM-L44P,PM-K44P,PM-R44P,PM-R44P,PM-T54,PM-R54,PM-F54,PM-Y54,PM-L54,EX-15E EX-17E EX-15 EX-19A EX-19B EX-17 EX-14A EX-14A-PN EX-14B EX-22A EX-22A-PN EX-22B EX-22B-PN EX-21A EX-21A-PN EX-21B-PN EX-21B EX-23 EX-23-PN EX-24A EX-24B EX-24A-PN EX-24B-PN EX-26A EX-26A-PN EX-26B EX-26B-PN EX-28A EX-28A-PN EX-28B EX-28B-PN EX-29A EX-29A-PN
