滬工電感式傳感器LJ18A3-8-Z/BX 三線NPN常開接近開關(guān)直流24V
產(chǎn)品概述
滬工LJ18A3-8-Z/BX電感式接近開關(guān)是一種非接觸式位置檢測傳感器，采用直流24V供電和三線NPN常開輸出方式。該產(chǎn)品基于高頻振蕩原理設(shè)計，當(dāng)金屬物體接近感應(yīng)面時，通過電磁感應(yīng)產(chǎn)生動作信號，無需機械接觸即可實現(xiàn)精準檢測。傳感器采用M18圓柱形螺紋結(jié)構(gòu)，外殼為金屬材質(zhì)，具有耐腐蝕、抗沖擊等特點，適合工業(yè)環(huán)境使用。檢測距離為8mm，響應(yīng)頻率快，可滿足自動化設(shè)備對位置檢測的快速響應(yīng)需求。產(chǎn)品廣泛應(yīng)用于機床、包裝機械、自動化生產(chǎn)線等領(lǐng)域的定位、計數(shù)及安全防護控制。136
工作原理
該接近開關(guān)由振蕩器、信號處理電路和輸出驅(qū)動三部分組成。振蕩器在感應(yīng)面產(chǎn)生交變磁場，當(dāng)金屬物體進入磁場范圍時，物體內(nèi)部產(chǎn)生渦流導(dǎo)致振蕩能量衰減，觸發(fā)開關(guān)狀態(tài)變化。NPN型輸出采用集電極開路形式，可與PLC、繼電器等控制設(shè)備直接配合使用。直流24V供電設(shè)計兼容大多數(shù)工業(yè)控制系統(tǒng)電壓標準，三線制接線方式（棕色接正極、藍色接負極、黑色為信號輸出）簡化了安裝流程。產(chǎn)品對鐵質(zhì)金屬具有最佳檢測靈敏度，同時支持不銹鋼、鋁等多種金屬材料的穩(wěn)定檢測。2711
產(chǎn)品特點
- 結(jié)構(gòu)特性：直徑18mm的緊湊圓柱形設(shè)計，螺紋安裝方式便于固定和調(diào)整位置，IP67防護等級能適應(yīng)粉塵、油污等復(fù)雜工況環(huán)境。2. 電氣性能：工作電壓范圍DC6-36V寬電壓設(shè)計，內(nèi)置反向極性保護，輸出電流達300mA可直接驅(qū)動小型負載。3. 環(huán)境適應(yīng)性：-20℃~+70℃的工作溫度范圍，內(nèi)置防短路和過載保護電路，確保在工業(yè)環(huán)境中的長期穩(wěn)定運行。4. 安裝便利：非埋入式感應(yīng)方式允許傳感器與檢測物體保持一定距離，減少機械磨損，延長使用壽命。41218
應(yīng)用場景
該傳感器特別適用于需要快速響應(yīng)的自動化控制場合，如：1. 數(shù)控機床的刀具位置檢測與行程限位；2. 包裝機械的物料計數(shù)與到位檢測；3. 自動化裝配線的工件定位與流程控制；4. 物流分揀系統(tǒng)的金屬物體識別。產(chǎn)品采用無觸點設(shè)計，避免了傳統(tǒng)機械開關(guān)的磨損問題，高頻操作次數(shù)可達100萬次以上，顯著降低設(shè)備維護需求。其穩(wěn)定的檢測性能有助于提高生產(chǎn)線的運行效率和可靠性。5920
