LJD-3008C(接近开关) 价格 生产厂家
产品概述
LJD-3008C是一款高性能电感式接近开关，采用非接触式检测原理，专为工业自动化环境设计。该产品通过电磁感应技术实现对金属物体的精准检测，具有响应速度快、使用寿命长等特点。其紧凑的圆柱形结构（直径12mm）适合空间受限的安装场景，外壳采用镍镀黄铜材质，兼具机械强度与耐腐蚀性。产品系列包含直流三线型（NPN/PNP输出）和交流二线型，电压覆盖DC6-36V或AC90-250V范围，可满足不同电气系统的需求。1618
技术原理
LJD-3008C基于电磁感应工作原理，内部由振荡器、信号处理电路和输出驱动三大部分构成。当金属目标进入传感器产生的交变磁场时，目标表面会形成涡流导致磁场衰减，后级电路将此变化转换为开关信号。该设计确保了对铁质材料的标准检测距离达4mm（铜铝等非铁金属检测距离会按衰减系数降低），且不受油污、粉尘等非金属介质影响。产品内置LED状态指示灯，便于现场调试和维护。1524
应用领域
该产品广泛应用于机械设备定位、自动化生产线计数、电梯平层控制、包装机械等场景。在机床行业用于刀具限位保护，在冶金设备中实现辊道速度监测，在物流分拣系统完成金属物件识别。其防护等级达到IP67，可适应-25℃至70℃的工作环境，特别适合食品加工、汽车制造等需要防尘防溅的工况。典型应用案例包括冲床安全联锁、AGV小车导航和立体仓库位置检测等。21617

Product Introduction
The LJD-3008C inductive proximity sensor delivers reliable metal detection in industrial automation systems. Featuring a robust brass housing with nickel plating, this cylindrical sensor (12mm diameter) operates on electromagnetic field distortion principle, providing non-contact sensing up to 4mm for ferrous targets. Available in both 3-wire DC (NPN/PNP) and 2-wire AC versions, it supports wide voltage ranges (DC6-36V/AC90-250V) for flexible integration. The compact design incorporates status LED for visual operation feedback.1624
Technical Features
With oscillation-decay detection technology, the sensor generates stable alternating electromagnetic field. When metal objects enter this field, eddy current effects trigger signal processing circuitry to switch output states. The copper-nickel alloy housing ensures resistance to mechanical stress and chemical corrosion, while PBT sensing face maintains stable performance in humid conditions. Built-in reverse polarity protection and surge absorption enhance electrical reliability. Standard models offer ≤3V voltage drop and 200mA output capacity.51822
Typical Applications
Ideal for position verification in CNC machines, conveyor belt monitoring, and automated assembly lines. Frequently deployed for liquid level control in stainless steel tanks, security door monitoring, and robotic arm position feedback. The IP67 protection allows operation in wood processing, pharmaceutical packaging and other demanding environments where dust/water exposure exists. Customizable cable lengths and connector options available for special installation requirements.21617
Manufacturer Profile
Produced by a specialized sensor manufacturer with extensive experience in industrial automation components. The production facility utilizes automated winding machines and computerized testing systems to ensure consistent quality. Comprehensive product range includes various sensing distances (1-40mm) and housing styles (cylindrical/rectangular). Technical support team provides application consulting and customized solutions for special detection scenarios.91419
