滬工LJ12A3-4-J/EZ接近開關(guān)產(chǎn)品介紹（中英文）
【中文版】
LJ12A3-4-J/EZ型接近開關(guān)是專為工業(yè)自動化控制設(shè)計的非接觸式檢測裝置，采用220V交流供電的二線制結(jié)構(gòu)，具備M12標(biāo)準(zhǔn)螺紋封裝，適用于多種工業(yè)場景的物體位置檢測需求。該產(chǎn)品以電磁感應(yīng)原理為基礎(chǔ)，通過金屬目標(biāo)物的接近實現(xiàn)信號觸發(fā)，無需物理接觸即可完成精準(zhǔn)檢測。
產(chǎn)品采用緊湊型圓柱體結(jié)構(gòu)設(shè)計，M12×1mm螺紋規(guī)格便于快速安裝，主體外殼選用耐腐蝕金屬材質(zhì)結(jié)合工程塑料防護層，可在-25℃至+70℃溫度范圍內(nèi)穩(wěn)定工作。感應(yīng)面防護等級符合工業(yè)防塵防水要求，有效適應(yīng)油污、粉塵等復(fù)雜工況環(huán)境。常開型（NO）輸出模式簡化了控制系統(tǒng)布線，當(dāng)檢測物體進入4mm有效感應(yīng)范圍時立即輸出導(dǎo)通信號。
本產(chǎn)品適用于自動化設(shè)備定位檢測、傳送帶物料監(jiān)控、機械臂動作控制等領(lǐng)域，特別適合機床加工、包裝機械、物流分揀等需要快速響應(yīng)的工業(yè)場景。內(nèi)置過載保護電路和抗干擾屏蔽層設(shè)計，有效降低誤觸發(fā)概率。接線端子采用防松脫結(jié)構(gòu)，確保長期振動環(huán)境下的連接可靠性。建議安裝時保持感應(yīng)面與金屬物體平行，并預(yù)留適當(dāng)安全距離以避免碰撞損壞。

【English Version】
The LJ12A3-4-J/EZ proximity switch is a non-contact detection device specifically designed for industrial automation control. Operating on 220V AC power with two-wire configuration, it features M12 standard threaded housing, making it suitable for object position detection in various industrial applications.
Utilizing electromagnetic induction principle, this switch activates signals through the approach of metal targets without physical contact. The compact cylindrical design with M12×1mm thread allows quick installation. The housing combines corrosion-resistant metal with engineering plastic protection layer, ensuring stable operation within -25℃ to +70℃ temperature range. The open-type (NO) output simplifies control system wiring, instantly delivering conduction signals when objects enter the 4mm effective sensing range.
Ideal for equipment positioning in automated systems, conveyor belt monitoring, and robotic arm control, this product excels in machine tool processing, packaging machinery, and logistics sorting applications requiring fast response. The built-in overload protection and anti-interference shielding effectively reduce false triggering. Vibration-resistant terminals maintain connection reliability in dynamic environments. Installation should maintain parallel alignment between sensing surface and target objects, with adequate safety clearance to prevent mechanical impact.
