1、限位開關(guān)普遍用于各類機(jī)床和起重機(jī)械，用以控制其行程、進(jìn)行終端限位保護(hù)。 2、在我們生活中常用電梯的控制電路中，還利用限位開關(guān)來控制開關(guān)轎門的速度、自動(dòng)開關(guān)門的限位、轎廂的上、下限位保護(hù)。 3、限位開關(guān)可以安裝在相對靜止的物體（如固定架、門框等，簡稱靜物）上或者運(yùn)動(dòng)的物體(如行車、門等，簡稱動(dòng)物)上。當(dāng)動(dòng)物接近靜物時(shí)，開關(guān)的連桿驅(qū)動(dòng)開關(guān)的接點(diǎn)引起閉合的接點(diǎn)分?jǐn)嗷蛘邤嚅_的接點(diǎn)閉合。由開關(guān)接點(diǎn)開、合狀態(tài)的改變?nèi)タ刂齐娐泛蜋C(jī)構(gòu)的動(dòng)作。</p><p style="text-indent:25px">限位開關(guān)構(gòu)造分為三類：1、活塞型：根據(jù)密封方法不同，有表中的A型和B型2個(gè)種類。A型是用O型環(huán)或薄膜密封的，由于密封橡膠沒有外露，在**工作機(jī)械的切割碎屑方面功能較強(qiáng)大，但其反面影響是，有可能會(huì)將砂子、切割粉末等壓入活塞的滑動(dòng)面。B型雖然不會(huì)把砂子、切割粉末等壓入，且密封性能優(yōu)于A型，但由于熾熱的切割碎屑飛濺過來，有可能會(huì)損壞橡膠帽。因此，要根據(jù)使用場所的不同選用A型或B型。而柱塞型仍然通過柱塞的往復(fù)運(yùn)動(dòng)壓縮或吸進(jìn)空氣。為此，如果長時(shí)間將柱塞壓入，限位開關(guān)內(nèi)的壓縮空氣逸失，內(nèi)部壓力將與大氣壓相同，即使急于讓柱塞復(fù)位，柱塞卻有遲緩復(fù)位的傾向。為了避免發(fā)生這種故障，設(shè)計(jì)時(shí)，根據(jù)柱塞的壓入將空氣的壓縮量控制在限位開關(guān)內(nèi)部全部空氣量的20%以內(nèi)。另外，為了延長微動(dòng)開關(guān)的壽命，在這一構(gòu)造內(nèi)部設(shè)置了一個(gè)OT吸收機(jī)構(gòu)，該OT吸收機(jī)構(gòu)采用OT吸收彈簧，用以吸收殘余的柱塞的行程。該機(jī)構(gòu)相對于柱塞的運(yùn)動(dòng)，在中途停止按壓微動(dòng)開關(guān)輔助柱塞的行程。2、鉸鏈擺桿型：在擺桿端部(滾珠)，柱塞的行程量根據(jù)擺桿的比例擴(kuò)大，因此，一般不使用OT吸收機(jī)構(gòu)。3、旋轉(zhuǎn)擺桿型限位開關(guān)又稱行程開關(guān)。</p><div

style="text-indent:25px">限位開關(guān)也可分為旋轉(zhuǎn)限位開關(guān)及直行限位開關(guān)。限位開關(guān)的內(nèi)部主要是機(jī)械觸點(diǎn)，觸點(diǎn)可以是常開，也可以是常閉。該觸點(diǎn)無源，所以不分NPN和PNP，進(jìn)線是24V，出線也是24V因此不挑剔PLC。接近開關(guān)無需與檢測物質(zhì)接觸，但是檢測物質(zhì)的材質(zhì)需要是金屬，因?yàn)闊o需與檢測接觸，因此它的特點(diǎn)是工作可靠、壽命長、功耗低、復(fù)定位精度高、操作頻率高以及適應(yīng)惡劣的工作環(huán)境等。接近開關(guān)分為PNP和NPN兩種，因此在選擇傳感器時(shí)需要確認(rèn)好PLC的接法。限位開關(guān)重要的作用是對機(jī)械進(jìn)行連鎖保護(hù)。使用限位開關(guān)時(shí)根據(jù)安裝環(huán)境選擇防護(hù)形式。安全限位開關(guān)能夠可靠地監(jiān)控并保護(hù)護(hù)罩、門及蓋子。山東感應(yīng)限位開關(guān)生產(chǎn)廠商</p><p
