意大利AECO品部分產(chǎn)品介紹：
1.AECO 電容式連續(xù)液位計(jì)
Aeco展示了適用于檢測(cè)水和導(dǎo)電液體的新型SLC系列電容式連續(xù)物位計(jì)。所述傳感器設(shè)置有四個(gè)電極長(zhǎng)度：500-1000-1500和2000毫米。在AISI 316鋼中具有PTFE涂層。傳感器在罐體上的固定包括AISI 303中的?”氣體連接和25 Bar的壓力密封。液位測(cè)量以4-20 mA模擬形式提供，并根據(jù)要求提供閾值設(shè)備可調(diào)節(jié)，以在編程級(jí)別繼電器。電氣連接為2芯M12連接器連接。它們用作金屬或絕緣材料制成的罐和容器中的連續(xù)液位控制器。該連續(xù)液位計(jì)也可以提供用于油和非導(dǎo)電液體的型號(hào)。

2.AECO 微型光電傳感器
AECO展示了FS系列的新型微型光電管產(chǎn)品線。緊湊的結(jié)構(gòu)特別適合安在狹窄的空間中。在12-24Vdc NPN和PNP版本中提供了四個(gè)檢測(cè)系統(tǒng)，可以在有和沒有背景的情況下對(duì)材料進(jìn)行直接反射，并通過反射器和光幕+接收器進(jìn)行偏振反射。靈敏度由電位計(jì)和綠色穩(wěn)定度LED調(diào)節(jié)，當(dāng)完全打開時(shí)，表明調(diào)節(jié)的質(zhì)量。可以使用特殊的選擇器來切換亮/暗脈沖，從而確定使用該功能所必需的功能。防護(hù)等級(jí)為IP67，整個(gè)系列的電氣連接都帶有一個(gè)懸空的M8x1連接器。

3.AECO 光電傳感器
該光電傳感器是電子換能器發(fā)射調(diào)制光，當(dāng)一個(gè)對(duì)象影響它們的作用半徑提供輸出信號(hào)。該范圍包括具有不同光纖型號(hào)的圓柱型執(zhí)行器M18，平行六面體，前叉和M18。提供直接反射(漫射)，紅外反射器反射或紅色偏振光反射以及帶有獨(dú)立投影儀和接收器的光柵。所有版本均隨附電纜或每個(gè)連接器帶有M12連接。

4.AECO 磁性傳感器
所述磁性傳感器Reed和磁鐵由一個(gè)的簧片開關(guān)與保護(hù)玻璃安瓿含有這降低它的機(jī)械和電氣磨損惰性氣體接觸。一切都封在塑料或金屬外殼中，并用環(huán)氧樹脂浸漬，以確保產(chǎn)品免受潮氣，沖擊和振動(dòng)。該系列包括圓柱和平行六面體執(zhí)行器，提供帶有開放或交換觸點(diǎn)的版本。可以使用各種形狀和大小的磁鐵來操作這些傳感器。

5.AECO 微型光電傳感器
FS 系列 的 微型光電傳感器 設(shè)計(jì)緊湊，特別適合在狹窄的空間中安。 有在版本提供四個(gè)檢測(cè)系統(tǒng) NPN和PNP 從 12-24Vcc ，對(duì)具有和不具有背景材料漫反射，偏振的回射屏障和投影+接收機(jī)。 靈敏度由電位計(jì)和綠色穩(wěn)定度LED調(diào)節(jié)，當(dāng)完全打開時(shí)，表明調(diào)節(jié)的質(zhì)量。 可以使用特殊的選擇器來切換亮/暗脈沖，從而確定使用該功能所必需的功能。

今天就講解一下接觸器自鎖到底怎么接線？在了解接觸器自鎖的接線以前，我們首先要了解接觸器的原理，還有常開常閉觸點(diǎn)，不知道這些我們接線還是一竅不通，下面我們先講解一下接觸器它的原理構(gòu)造。380伏交流接觸器有三個(gè)主觸頭也就是電源進(jìn)線和負(fù)載端出線，進(jìn)線分別是三相火線L1L2和L3,負(fù)載端出線分別是T1T2和T3,接觸器主觸頭進(jìn)線和出線上下一一對(duì)應(yīng)，分別是L1對(duì)應(yīng)T1,L2對(duì)應(yīng)T2L3對(duì)應(yīng)T3,主觸頭在接觸器不吸合的狀態(tài)下是常開狀態(tài)什么是常開？常開的意思就是說觸點(diǎn)是斷開的，不聯(lián)通的，常閉的意思就是說觸點(diǎn)是聯(lián)通的，常開和常閉一定要充分理解才可以接觸器還有一個(gè)常開輔助觸頭，也就是右方的第四個(gè)接觸器觸點(diǎn)，上下也是一一對(duì)應(yīng)，接觸器不吸合一直是常開狀態(tài)，輔助觸頭的作用就是輔助按鈕控制接觸器的，而主觸頭的作用是控制負(fù)載端的，所以分為主觸頭和輔助觸頭。
