接近開關又稱無觸點行程開關,它除可(kě)以完(wán)成行程(chéng)控製(zhì)和限(xiàn)位保護(hù)外,還是一種非接觸型(xíng)的檢測(cè)裝置,用(yòng)接近開(kāi)關作檢測零(líng)件(jiàn)尺寸(cùn)和測速(sù)等,也可用於變頻計(jì)數器、變頻(pín)脈衝(chōng)發(fā)生(shēng)器、液麵控(kòng)製和加工(gōng)程序的自動銜接(jiē)等。特點有工作(zuò)可靠、壽命長、功耗低、複定位(wèi)精度高、操作頻率高以及適應惡劣的工作環境BI1.5-M8-AN6X
等。

選用注(zhù)意事項
在(zài)一般的工業生產(chǎn)場所(suǒ),通常(cháng)都選(xuǎn)用渦流式接近開關(guān)和電容式接近開關。因(yīn)為這兩種(zhǒng)接近開(kāi)關(guān)對(duì)環(huán)境的要求條件較低(dī)。
當被測對象是(shì)導電物體或可以固定在一塊(kuài)金屬物上的物體(tǐ)時,一般都選用(yòng)渦(wō)流式(shì)接近開關(guān),因為它的響應頻率高(gāo)、抗(kàng)環(huán)境幹擾性(xìng)能(néng)好、應用範圍(wéi)廣、價格較低。
若所測對(duì)象是(shì)非(fēi)金屬(shǔ)(或金(jīn)屬)、液位高(gāo)度、粉狀物高度、塑料、煙草(cǎo)等。則應選用電容式接近開關。這種開(kāi)關的響應頻率(lǜ)低(dī),但穩定性好。安(ān)裝時應(yīng)考慮環境因素的影響。
若被測物為導磁材料或(huò)者為了區別和它在(zài)一同運動(dòng)的物體而把磁(cí)鋼埋在被測(cè)物體內時,應選用霍爾接近開關(guān),它的價格低。
在環境條(tiáo)件比較(jiào)好、無粉塵汙染的(de)場合,可采用光電接(jiē)近開關。光電接近開關工作時對被(bèi)測對象幾乎無任(rèn)何影響。因此,在要求較高的傳(chuán)真機上,在煙(yān)草機械上都(dōu)被廣泛地使用。
在防盜係統中,自(zì)動門通常使(shǐ)用熱釋電接近(jìn)開關(guān)、超聲波(bō)接近開(kāi)關、微波(bō)接近(jìn)開關。 無(wú)論選用哪種(zhǒng)接近開關,都應注意對工(gōng)作電壓(yā)、負載(zǎi)電流、響應(yīng)頻(pín)率、檢測距離(lí)等各項指標的要求
