Hertz Electronic公司用大块不列颠合金(一种锑锡铜合金)在法国生产出了红外开关,称为观察者。红外开关的功能:当罪犯进入时,提供报警信号,在黑夜中保护电能和防止可能发生的不幸情况。红外开关安装在住宅旁的区域内,当红外开关的报警区内有人出现时,光便接通,警戒范围16m×29m。用特殊的光阑可使红外开关的警戒区角度由110°减小到90°,60°或25°,红外开关的转换电流为10A,在其中还装有内装
Hertz Electronic produced infrared switches, called observers, in France with large British alloys, an antimony-tin-copper alloy. Infrared switch function: When criminals enter, provide an alarm signal to protect the electricity in the dark and prevent possible unfortunate situations. Infrared switch installed in the area next to the residence, when the infrared switch alarm zone appeared, the light will be connected, the warning range 16m × 29m. With a special diaphragm can make the infrared switch alarm zone angle from 110 ° to 90 °, 60 ° or 25 °, the infrared switch to convert the current 10A, which also contains a built-in
