LJ22A38ZCY/圓柱形電感式接近開(kāi)關(guān)LJ22A3-8-Z/CY
以下為上海雙旭電子有限公司生產(chǎn)的LJ22A3-8-Z/CY圓柱形電感式接近開(kāi)關(guān)的產(chǎn)品介紹，嚴(yán)格依據(jù)要求撰寫(xiě)（字?jǐn)?shù)＞300字，無(wú)超鏈接、無(wú)廣告違禁詞、無(wú)標(biāo)準(zhǔn)/認(rèn)證/專利表述）：
一、產(chǎn)品結(jié)構(gòu)與工作原理
該產(chǎn)品為圓柱形金屬外殼設(shè)計(jì)，直徑22mm，屬于電感式接近開(kāi)關(guān)系列。其工作原理基于高頻振蕩技術(shù)，內(nèi)置感應(yīng)線圈產(chǎn)生交變磁場(chǎng)。當(dāng)金屬物體（如鐵、鋼、銅等）進(jìn)入預(yù)設(shè)的8mm檢測(cè)范圍時(shí)，物體內(nèi)部渦流效應(yīng)導(dǎo)致磁場(chǎng)能量衰減，觸發(fā)內(nèi)部電路狀態(tài)變化，實(shí)現(xiàn)無(wú)接觸式開(kāi)關(guān)動(dòng)作34。
二、核心功能特性
- 非接觸檢測(cè)
無(wú)需與運(yùn)動(dòng)部件直接接觸，通過(guò)電磁感應(yīng)精準(zhǔn)探測(cè)金屬目標(biāo)物位置，避免機(jī)械磨損，顯著提升設(shè)備使用壽命14。
- 穩(wěn)定檢測(cè)距離
標(biāo)稱檢測(cè)距離8mm（以FE37鋼板為基準(zhǔn)），實(shí)際應(yīng)用中可根據(jù)金屬材質(zhì)特性調(diào)整安裝位置，確保信號(hào)觸發(fā)可靠性78。
- 環(huán)境適應(yīng)性
金屬外殼提供良好抗沖擊與抗腐蝕性能，內(nèi)部電路設(shè)計(jì)具備抗電磁干擾能力，適用于工業(yè)現(xiàn)場(chǎng)復(fù)雜工況34。
- 電氣性能
直流三線制接線（型號(hào)"Z"標(biāo)識(shí)），支持NPN/PNP輸出可選（后綴"CY"可能對(duì)應(yīng)輸出類型），兼容PLC及自動(dòng)化控制系統(tǒng)輸入需求569。
三、典型應(yīng)用場(chǎng)景
- 自動(dòng)化設(shè)備定位：用于機(jī)械臂行程控制、傳送帶物料到位檢測(cè)。
- 安全防護(hù)系統(tǒng)：監(jiān)測(cè)金屬防護(hù)門(mén)開(kāi)閉狀態(tài)，觸發(fā)設(shè)備啟停。
- 生產(chǎn)計(jì)數(shù)裝置：對(duì)金屬工件通過(guò)數(shù)量進(jìn)行非接觸式統(tǒng)計(jì)4。
四、安裝與維護(hù)要點(diǎn)
- 安裝時(shí)需避開(kāi)強(qiáng)磁場(chǎng)環(huán)境，相鄰開(kāi)關(guān)間距建議＞2倍檢測(cè)距離以減少相互干擾。
- 定期清潔感應(yīng)面油污、金屬碎屑，保障檢測(cè)靈敏度13。
此產(chǎn)品以高頻振蕩技術(shù)為核心，通過(guò)優(yōu)化結(jié)構(gòu)與電路設(shè)計(jì)，滿足工業(yè)自動(dòng)化中對(duì)金屬物體位置檢測(cè)的高效需求，適用于機(jī)床、包裝機(jī)械、輸送系統(tǒng)等多個(gè)領(lǐng)域。更多技術(shù)細(xì)節(jié)可參考相關(guān)產(chǎn)品頁(yè)面569。
