BES-M12-MI-PSC40B-BP03,BALLUFF巴魯夫限位開關(guān)樣本
用能感知溫度變化的元件做成的開關(guān)叫熱釋電式接近開關(guān)
這種開關(guān)是將熱釋電器件安裝在開關(guān)的檢測面上，當(dāng)有與環(huán)境溫度
德巴魯夫BALLUFF光電開關(guān)當(dāng)觀察者或系統(tǒng)對波源的距離發(fā)生
Photovoltaic device receives the reflected light after
the signal output, which can "sense" an object closer.
When an object close to the same, the output of Pyroelectr
made. Doppler effect can be made use of ultrasonic proximity switches
改變時，接近到的波的頻率會發(fā)生偏移，這種現(xiàn)象稱為多普勒效應(yīng)

BES-M12-MI-PSC40B-BP03,BALLUFF巴魯夫限位開關(guān)樣本

用光電效應(yīng)做成的開關(guān)叫光電開關(guān)。將發(fā)光器件與光電器件按
一定方向裝在同一個檢測頭內(nèi)。當(dāng)有反光面(被檢測物體)接近時
光電器件接收到反射光后便在信號輸出，由此便可“感知”有物體接近。
ic will change, thus it can detect an object approaching.
Sonar and radar using the principle of this effect is
同的物體接近時，熱釋電器件的輸出便變化，由此便可檢測出有物體接近。
Sonar and radar using the principle of this effect is made. Doppler
effect can be made use of ultrasonic proximity switches
