中文介紹： E3S-R2N3光電開關(guān)是一種反饋反射式光電開關(guān)，具有廣泛的工業(yè)應(yīng)用價值。它采用直流型電源，輸出類型為NPN，動作模式為常開（NO）加常閉（NC），檢測范圍可達(dá)2米±10%，且檢測目標(biāo)為不透明物體。這種光電開關(guān)使用紅外光（660nm）作為光源，響應(yīng)時間為1ms，接通延時為1.5ms。其電源電壓范圍較廣，直流型為DC12—24V（6-36V），能夠適應(yīng)不同設(shè)備的供電需求。

在設(shè)計上，E3S-R2N3光電開關(guān)的檢測范圍調(diào)節(jié)方式為固定（Fixed），這使得其在特定應(yīng)用場景中能夠保持穩(wěn)定的檢測性能。它適用于多種工業(yè)環(huán)境，如自動化生產(chǎn)線、物料輸送系統(tǒng)等，能夠有效檢測物體的存在與否，從而實現(xiàn)自動化控制。此外，該光電開關(guān)的耐電壓能力較強(qiáng)，充電部分與外殼間可承受AC1000V、50/60Hz的電壓，確保了其在復(fù)雜電氣環(huán)境中的可靠性。

英文介紹： The E3S-R2N3 photoelectric switch is a feedback reflective photoelectric switch with extensive industrial application value. It uses a direct current (DC) power supply, has an NPN output type, and features a Normally Open (NO) plus Normally Closed (NC) action mode. The detection range can reach 2 meters ± 10%, and the detection target is non-transparent objects. This photoelectric switch uses infrared light (660nm) as the light source, with a response time of 1ms and a turn-on delay of 1.5ms. Its power supply voltage range is quite wide, with a DC type of 12—24V (6-36V), capable of meeting the power supply requirements of different equipment.

In terms of design, the detection range adjustment method of the E3S-R2N3 photoelectric switch is fixed (Fixed), which ensures stable detection performance in specific application scenarios. It is suitable for a variety of industrial environments, such as automated production lines and material conveying systems, and can effectively detect the presence or absence of objects to achieve automated control. In addition, the photoelectric switch has strong voltage endurance, with the charging part and the housing able to withstand an AC voltage of 1000V at 50/60Hz, ensuring its reliability in complex electrical environments.

E3S-R2N3光電開關(guān)的價格會因市場供需、銷售渠道以及購買數(shù)量等因素而有所波動。一般來說，其價格在幾十元到一百多元人民幣之間。具體價格還需根據(jù)實際購買情況與供應(yīng)商進(jìn)行確認(rèn)。

E3S-R2N3光電開關(guān)的生產(chǎn)廠家眾多，其中較為知名的有上海雙旭電子有限公司、上海經(jīng)馳實業(yè)有限公司等。這些廠家在光電開關(guān)領(lǐng)域擁有豐富的生產(chǎn)經(jīng)驗和技術(shù)積累，能夠提供質(zhì)量可靠、性能穩(wěn)定的產(chǎn)品。此外，國際工牌（中國滬工）也生產(chǎn)該型號的光電開關(guān)，其產(chǎn)品在市場上也具有一定的份額。
