瑞科电感式直流npn pnp方形接近开关sn0
产品概述
瑞科电感式直流方形接近开关SN0系列是一款高性能的非接触式检测传感器，采用先进的电感式感应技术，适用于金属物体的精准检测。该系列提供NPN和PNP两种输出型号，兼容直流电源（10-30VDC），具有响应速度快、稳定性强、安装便捷等特点。其方形结构设计紧凑，适合空间受限的工业场景，如自动化设备、机械限位、流水线分拣等。产品支持常开（NO）或常闭（NC）功能配置，可灵活适配不同控制需求。135
技术特点
SN0系列接近开关基于电磁感应原理，当金属物体进入预设检测范围（如4mm或5mm）时，传感器会触发信号输出。NPN型为电流 sinking 输出，适合连接PLC的共阳极输入模块；PNP型为电流 sourcing 输出，适用于共阴极电路。产品采用全封闭设计，具备抗振动、耐油污和防尘性能，可在-25℃至+70℃环境下稳定工作。内置LED状态指示灯便于实时监测工作状态，且功耗低（≤10mA），适合长期连续运行。131619
应用场景
广泛应用于工业自动化领域，如机床刀具定位、包装机械物料检测、电梯门控安全感应等。其方形外壳（典型尺寸18×18mm）支持多种安装方式，侧面或顶部感应方向可选。例如，在食品加工设备中可用于不锈钢容器的液位检测，在物流分拣系统中实现金属托盘的位置识别。产品兼容三线制接线（电源+/−及信号线），简化了系统集成流程。182123

Product Overview
The RIKO inductive DC square proximity switch SN0 series is a high-performance non-contact sensor designed for precise metal object detection. Featuring NPN and PNP output options, it operates on a DC power supply (10-30V) with fast response and stable performance. Its compact square housing suits space-constrained industrial applications like automation equipment, mechanical limit positioning, and conveyor sorting systems. The series supports normally open (NO) or normally closed (NC) configurations for flexible integration.1313
Key Features
Utilizing electromagnetic induction technology, the SN0 series triggers a signal when a metal target enters its sensing range (e.g., 4mm or 5mm). The NPN model offers sinking output for common-anode PLC inputs, while the PNP model provides sourcing output for common-cathode circuits. The fully enclosed design ensures resistance to vibration, oil, and dust, with reliable operation in temperatures from -25°C to +70°C. A built-in LED indicator simplifies status monitoring, and low power consumption (≤10mA) enables continuous use.161921
Applications
Ideal for industrial automation, including CNC tool positioning, packaging machine material detection, and elevator door safety sensing. The square form factor (e.g., 18×18mm) allows versatile mounting with side or top sensing orientations. Examples include stainless steel container level detection in food processing and metal pallet tracking in logistics. The three-wire connection (power +/− and signal) streamlines system integration.182223
Advantages
- High Reliability: Contactless design eliminates mechanical wear;
- Broad Compatibility: Detects various metals (iron, stainless steel, etc.);
- Flexible Options: NPN/PNP and NO/NC models for diverse circuit needs;
- Environmentally Safe: Lead-free materials align with industrial safety standards.
Popular models like SN04-N (NPN NO) and SN04-P (PNP NO) offer selectable sensing distances (4mm/5mm/10mm) and outputs.51316
