SC2020AB/圓柱形電感式接近開關(guān)SC-2020AB
以下是上海雙旭SC-2020AB圓柱形電感式接近開關(guān)的產(chǎn)品介紹，綜合搜索結(jié)果信息整理而成：
一、產(chǎn)品概述
SC-2020AB是一款圓柱形電感式接近開關(guān)，由上海雙旭電子有限公司研發(fā)生產(chǎn)。該產(chǎn)品采用非接觸式檢測原理，無需機(jī)械接觸即可感知金屬目標(biāo)物的靠近，適用于工業(yè)自動(dòng)化場景中的位置檢測、物體計(jì)數(shù)及限位控制任務(wù)136。
二、核心功能與特點(diǎn)
-
非接觸感應(yīng)機(jī)制
通過內(nèi)置振蕩器產(chǎn)生交變磁場，當(dāng)金屬物體進(jìn)入預(yù)設(shè)感應(yīng)范圍（典型檢測距離為20mm）時(shí)，金屬內(nèi)部產(chǎn)生的渦流導(dǎo)致磁場變化，觸發(fā)開關(guān)信號(hào)輸出。全程無物理接觸，避免機(jī)械磨損，延長使用壽命36。
-
環(huán)境適應(yīng)性優(yōu)化
- 防護(hù)設(shè)計(jì)：具備防水、防塵及耐腐蝕特性，適應(yīng)冶金、化工、輕紡等復(fù)雜工業(yè)環(huán)境；
- 抗震性能：內(nèi)部結(jié)構(gòu)穩(wěn)定，可承受設(shè)備運(yùn)行中的持續(xù)振動(dòng)13。
-
電氣特性
- 電源兼容性：支持直流10-30V寬電壓輸入（直流三線制）；
- 輸出配置：提供NPN/PNP晶體管輸出類型，負(fù)載電流≤300mA，可直接驅(qū)動(dòng)PLC或繼電器6。
三、典型應(yīng)用領(lǐng)域
- 機(jī)床設(shè)備：用于刀具位置監(jiān)控或工件到位檢測；
- 輸送系統(tǒng)：安裝在帶式/鏈?zhǔn)捷斔蜋C(jī)中，實(shí)現(xiàn)斷鏈保護(hù)或速度監(jiān)測（需配合信號(hào)處理器）；
- 生產(chǎn)線自動(dòng)化：完成物料計(jì)數(shù)、流水線分揀等流程控制123。
四、安裝與維護(hù)優(yōu)勢
圓柱形結(jié)構(gòu)（直徑20mm）便于嵌入式安裝，減少空間占用；外殼材質(zhì)堅(jiān)固，日常維護(hù)僅需定期清除表面積塵16。
