SA-3015B接近开关/SA3015B
SA-3015B圆盘形接近开关产品概述
SA-3015B圆盘形接近开关是一款专为工业自动化和机械设备设计的非接触式传感器，适用于金属物体的检测。该产品采用电磁感应原理，当金属目标进入其感应范围时，磁场变化触发开关信号输出，无需物理接触即可实现精准控制。其圆盘形结构设计便于安装，适用于机床、冶金、化工等领域的限位、计数及定位控制。产品具有响应速度快、使用寿命长、抗干扰能力强等特点，并支持防水、防震设计，适应复杂工业环境。126
SA-3015B Proximity Switch Product Description
The SA-3015B disc-type proximity switch is a non-contact sensor designed for industrial automation and mechanical equipment, specifically for metal object detection. Based on electromagnetic induction technology, it generates an output signal when a metal target approaches its sensing range, eliminating the need for physical contact. The compact disc-shaped housing ensures easy installation, making it suitable for applications such as position control, counting, and safety protection in machinery, metallurgy, and chemical industries. With features like high-frequency response, durability, and resistance to environmental interference, it operates reliably in demanding conditions. The device also supports waterproof and shockproof configurations.1619
技术特性与工作原理
SA-3015B的核心组件包括振荡器、开关电路和放大输出电路。振荡器产生交变磁场，金属物体靠近时引发涡流导致磁场衰减，后级电路将此变化转换为开关信号。检测距离稳定，典型值为15mm（±10%），支持直流或交流供电（如24VDC或220VAC）。产品提供多种输出形式（如NPN/PNP），兼容PLC控制系统，满足自动化产线的多样化需求。其无触点设计避免了机械磨损，提升了操作频率和定位精度。2416
Technical Specifications & Operation Principle
The SA-3015B integrates an oscillator, switching circuit, and amplifier. The oscillator generates an alternating magnetic field, which is disrupted by eddy currents when a metal object enters its detection zone (typically 15mm±10%). This change is processed into a clean output signal for control systems. Compatible with both DC (e.g., 24V) and AC (e.g., 220V) power supplies, it offers flexible wiring options (NPN/PNP) for PLC integration. The contactless mechanism ensures high operational frequency and eliminates mechanical wear, ideal for precision tasks in automated production lines.41327
应用场景与优势
SA-3015B广泛应用于电梯位置检测、传送带速度监控、液位控制及安全防护系统。例如，在包装机械中实现物料尺寸检测，或在流水线上计数产品通过数量。其优势包括抗油污、耐腐蚀性能，以及适应-25℃至+70℃的工作温度范围。圆盘外形可灵活选择齐平或非齐平安装方式，满足不同空间限制需求。2618
Applications & Key Benefits
The SA-3015B is widely used in elevator positioning, conveyor speed monitoring, liquid level control, and safety systems. Typical scenarios include size verification in packaging machines or item counting on production lines. Its robust construction resists oil, dust, and corrosive substances, with an operating temperature range of -25℃ to +70℃. The disc shape allows flush or non-flush mounting, adapting to spatial constraints. These features ensure reliability in diverse industrial settings.131828
