工作原理
該開(kāi)關(guān)內(nèi)部集成高頻振蕩電路、檢波電路和輸出驅(qū)動(dòng)電路。當(dāng)通電時(shí)，感應(yīng)面產(chǎn)生交變電磁場(chǎng)；金屬物體進(jìn)入檢測(cè)范圍（4mm）時(shí)，渦流效應(yīng)吸收磁場(chǎng)能量導(dǎo)致振蕩衰減，觸發(fā)輸出信號(hào)變化。NPN型三線輸出兼容多數(shù)PLC和控制器，常開(kāi)模式在無(wú)金屬接近時(shí)保持?jǐn)嚅_(kāi)狀態(tài)，檢測(cè)到目標(biāo)后閉合輸出。其響應(yīng)時(shí)間短（約2.5ms），適合高速檢測(cè)場(chǎng)景。11419
技術(shù)特點(diǎn)
產(chǎn)品工作電壓覆蓋DC6-36V寬范圍，適應(yīng)不同電氣環(huán)境。外殼采用黃銅鍍鎳材質(zhì)，防護(hù)等級(jí)達(dá)IP67，具備防塵防水能力，可在-25℃至+70℃環(huán)境中穩(wěn)定工作。內(nèi)置反接保護(hù)、浪涌吸收和短路保護(hù)電路，提升可靠性。導(dǎo)線長(zhǎng)度標(biāo)準(zhǔn)配置1.2米，支持定制加長(zhǎng)線纜。檢測(cè)物體以鐵質(zhì)金屬為主，對(duì)其他金屬檢測(cè)距離略有差異。71214
應(yīng)用領(lǐng)域
廣泛應(yīng)用于自動(dòng)化設(shè)備的位置檢測(cè)、計(jì)數(shù)、安全防護(hù)等場(chǎng)景，如機(jī)械手臂定位、傳送帶物料檢測(cè)、沖床安全門(mén)監(jiān)控等。其緊湊尺寸（直徑12mm）適合空間受限的安裝環(huán)境，高重復(fù)精度（±0.1mm）滿足精密控制需求。產(chǎn)品兼容替代同類(lèi)進(jìn)口型號(hào)，性價(jià)比突出。122123
English Introduction
The LJ12A3-4-Z/BX inductive proximity switch is a non-contact metal detection sensor utilizing high-frequency oscillation technology. With DC 3-wire NPN normally open (NO) output, it reliably detects metallic objects within 4mm range without physical contact, ideal for industrial automation systems. The M12 cylindrical housing ensures easy installation in machinery, conveyor systems, and robotic applications. 17
Operating on electromagnetic principles, its internal oscillator generates a field that attenuates when metal targets approach, triggering the transistor output. The NPN configuration (sourcing output) works with most controllers, while the 6-36VDC wide voltage range enhances compatibility. Key features include IP67 protection, brass-nickel plated housing, and built-in reverse polarity/surge protection. 1419
Designed for harsh environments (-25°C to +70°C), this sensor excels in position sensing, object counting, and safety interlocks. Its 12mm diameter suits space-constrained setups, with 1.2m cable (customizable). Typical applications include CNC machine tooling, packaging equipment, and automated assembly lines, offering durable performance with minimal maintenance. 1223
