產(chǎn)品提供直流兩線制與三線制可選配置（NPN/PNP輸出），導(dǎo)線規(guī)格可選PVC或耐高溫硅膠材質(zhì)，線長(zhǎng)支持0.5-3米定制。安裝方式包含齊平式與非齊平式兩種方案，支持M12×1螺紋固定或支架輔助安裝。典型應(yīng)用涵蓋機(jī)床定位、輸送帶檢測(cè)、自動(dòng)化裝配線等多個(gè)領(lǐng)域，特別適用于需要抗電磁干擾的場(chǎng)合。
選型時(shí)需注意目標(biāo)物材質(zhì)特性，本產(chǎn)品對(duì)鐵磁性金屬具有最優(yōu)檢測(cè)靈敏度。建議定期清潔檢測(cè)面以保持最佳工作狀態(tài)，避免強(qiáng)腐蝕性環(huán)境長(zhǎng)期使用。產(chǎn)品出廠前經(jīng)過(guò)多道工序測(cè)試，確保批次一致性�？筛鶕�(jù)客戶(hù)需求提供定制化服務(wù)，包括特殊導(dǎo)線長(zhǎng)度、接插件選配等解決方案。
【English Version】
The LJ12A3-2(4)-Z/BY proximity sensor is an industrial-grade detection device employing non-contact sensing technology. Engineered with composite housing materials combining engineering plastics and metal components, its cylindrical structure ensures durability while maintaining signal stability. Available with 8-12mm detection ranges, this product provides flexible solutions for various positioning requirements.
Utilizing high-frequency oscillation circuit technology, the sensor generates stable switching signals through electromagnetic induction when metal targets enter its detection field. The built-in temperature compensation module enhances measurement consistency across operating temperatures from -25℃ to +70℃. With IP67 protection rating, it demonstrates reliable performance in dusty environments or occasional liquid exposure.
This product offers configurable wiring options including 2-wire and 3-wire DC circuits (NPN/PNP outputs), available with PVC or high-temperature silicone cables ranging from 0.5 to 3 meters. Installation flexibility is achieved through flush or non-flush mounting styles, compatible with M12×1 threaded fixtures or bracket assemblies. Typical applications span machine tool positioning, conveyor monitoring, and automated production lines, particularly effective in environments requiring electromagnetic interference resistance.
When selecting models, material characteristics of target objects should be considered, as the device shows optimal sensitivity towards ferrous metals. Regular maintenance including surface cleaning is recommended to sustain detection accuracy. Customization services are available for specialized requirements such as extended cable lengths and connector configurations. Each unit undergoes rigorous quality control processes to ensure product reliability.
