AL-09R磁性開(kāi)關(guān)有幾根線

磁性開(kāi)關(guān)有2根線或3根線。

?磁性開(kāi)關(guān)的線數(shù)主要分為兩線式和三線式兩種?，具體取決于其類型和應(yīng)用場(chǎng)景。兩線式磁性開(kāi)關(guān)有2根線（電源和負(fù)載串聯(lián)），而三線式磁性開(kāi)關(guān)有3根線（V+、V-和信號(hào)線）。

?磁性開(kāi)關(guān)的線數(shù)類型?

?兩線式磁性開(kāi)關(guān)?。

?線數(shù)?：2根（棕色線接電源正極，藍(lán)色線接電源負(fù)極）。??

?特點(diǎn)?：無(wú)源觸點(diǎn)（干接點(diǎn)），兼容AC/DC電源，接線簡(jiǎn)單，但響應(yīng)速度較慢（10-20ms），抗干擾能力較弱。??

?典型應(yīng)用?：簡(jiǎn)單通斷控制（如指示燈、門磁報(bào)警系統(tǒng)）。??

?三線式磁性開(kāi)關(guān)?。

?線數(shù)?：3根（棕色線接V+，藍(lán)色線接V-，黑色線為信號(hào)線）。??

?特點(diǎn)?：晶體管輸出（NPN或PNP型），需獨(dú)立DC供電（5-30V），響應(yīng)速度快（1-5ms），抗干擾能力強(qiáng)。??

?典型應(yīng)用?：PLC信號(hào)采集、高速檢測(cè)場(chǎng)景（如自動(dòng)化產(chǎn)線、安全聯(lián)鎖裝置）。??

?選型建議?

?優(yōu)先兩線式?：低成本、簡(jiǎn)單通斷控制（如照明）。??

?優(yōu)先三線式?：高頻動(dòng)作（>10次/秒）、長(zhǎng)距離傳輸或復(fù)雜電磁環(huán)境。??供應(yīng)元利富系列型號(hào)產(chǎn)品可以亞德克磁性開(kāi)關(guān)：
