style="text-indent:25px">限位開關就是用以限定機械設備的運動極限位置的電氣開關。限位開關有接觸式的和非接觸式的。接觸式的比較直觀，機械設備的運動部件上，安裝上行程開關，與其相對運動的固定點上安裝極限位置的擋塊，或者是相反安裝位置。當行程開關的機械觸頭碰上擋塊時，切斷了（或改變了）控制電路，機械就停止運行或改變運行。由于機械的慣性運動，這種行程開關有一定的“超行程”以保護開關不受損壞。非接觸式的形式很多，常見的有干簧管、光電式、感應式等，這幾種形式在電梯中都能夠見到。當然還有更多的先進形式。限位開關主要有開關元件，接線端子、開關操動件、傳動部分組成，根據(jù)開關觸頭接通和斷開機械機理，開關元件有以下兩類：慢動開關：開關的接通和斷開動作切換時間與開關的操動速度有關，操動速度越快，開關的切換也越快?？靹娱_關：開關的接通和斷開的轉換時間與開關**動的速度無關，只要開關操動部件**動到一定位置，開關便發(fā)生接通和斷開切換，此過程時間一般為彈簧彈跳所需時間，此時間極短，為一常數(shù)。四川機械限位開關機器隔爆型限位開關產(chǎn)品特點：內部可調節(jié)凸輪通過花鍵和彈簧安裝，開關凸輪的位置不用工具即可進行快速調整。</p><div

style="text-indent:25px">限位開關（行程開關）是一種低成本的檢測元件，限位開關適合于許多種狹小的安裝環(huán)境。開關堅固耐用，并有多種操作頭可選，適合多種應用。拆下外殼，內部的觸點塊的正面和側面都完全暴露在外，這對安裝接線非常有利，開關底部柔軟的電纜護套使安裝接線更方便。限位開關在電路中符號有三種，限位開關一種是常開接點，另一種是常閉接點，還有一種是一常開接點，一常閉接點的組合（兩個符號之間用虛線連接起來，表示聯(lián)動）。限位開關不包括液位開關、凸輪開關....等其他名稱的各種位置開關，其他的限位開關有各自的符號表達。</p><p style="text-indent:25px">限位開關的用途：當物體到達或離開某的位置時，開閉電氣回路。限位開關與普通手動開關的區(qū)別是：能檢測物體的有無，根據(jù)要求開閉電氣回路。例如：我們打開冰箱時，冰箱內的照明燈自動點亮；再如我們的微波爐，門沒有關好之前，轉動定時器不啟動；又如滾筒式洗衣機在關好門之前不啟動，而雙杠式洗衣機的脫水桶，在打開上蓋時停止轉動，并且抱閘停車。在工業(yè)生產(chǎn)中也有廣fan應用，可以用來進行安全防護；用于機床（CNC，MC機床）門開關時的安全防護。用于機械手等，用于原點確認進行位置指示，如現(xiàn)場安裝的閥門位置指示等；進行邏輯順序控制，如進行物體輸送的傳送帶，當物體到達某處后進行下一步操作。限位開關是一種位移傳感器。工作限位開關是用來給出機構動作到位信號的。</p><div

style="text-indent:25px">限位開關可覆蓋市場上絕大多數(shù)限位應用，有超過5000種型號可供組合，包括24種不同的操作頭、觸點模塊和接頭，限位單一操作頭有五種本體可選擇，操作頭360度選擇，3到4對觸點，觸點形式任意配置，快速接插件，可比普通接線快40%折疊。應用于各種機械、機床、紡織、塑機、物流，輕工、化工、冶金、建筑、航空、電力、汽車、傳輸、地鐵等各行各業(yè)。限位開關的優(yōu)勢：限位開關產(chǎn)品多數(shù)采用模塊化的結構形式，它通過75種組件，組成2000多種產(chǎn)品，選取方便快捷，從而簡化產(chǎn)品的選型、種類、安裝、調整、接線以及維護等限制。限位開關又稱行程開關。一體式限位開關KS-600產(chǎn)品特點：環(huán)境溫度：-20～85℃。四川機械限位開關機器</p><p style="text-indent:25px">地鐵也應用到了限位開關。四川機械限位開關機器</p><p style="text-indent:25px">限位開關的構成：接點金Au抗腐蝕性非常優(yōu)越，用于微小負載。因為其質地較柔軟(維氏硬度HV25～65)，因此較易黏著(接點黏著)，并且在接點接觸力較大的情況下接點容易凹陷。金、銀合金AuAg90％金、10％銀的合金抗腐蝕性非常優(yōu)越，硬度為HV30～90，比金高，因此廣fan用于微小負載用開關。白金、金、銀合金PGS69％金、25％銀、6％白金的合金抗腐蝕性非常優(yōu)越，硬度也與金銀合金相同，廣fan用于微小負載用開關。稱為作“1號合金”。銀、鈀合金AgPd抗腐蝕性較好，但較易吸附有機氣體生成聚合物。50％銀、50％鈀的情況下，硬度為HV100～200。銀Ag導電率、熱傳導率在金屬中是大的。雖然表現(xiàn)出較低的接觸電阻，但其缺點是，在硫化氣體的環(huán)境中較易生成硫化膜，在微小負載區(qū)域較易產(chǎn)生接觸不良。硬度為HV25～45。多用于一般負載用開關。銀、鎳合金AgNi90％銀、10％鎳的銀、鎳合金導電率與銀接近，在抗電弧、抗熔化方面表現(xiàn)優(yōu)良。硬度為HV65～115。銀、銦、錫合金AgInSn硬度、熔點較高，抗電弧性優(yōu)越，不易熔化或轉移。四川機械限位開關機器</p></p><br
