SD-3020C接近开关/SD3020C
产品概述
SD-3020C是一款圆盘式电感式接近开关，采用非接触式检测原理，适用于工业自动化控制场景。该产品通过电磁感应实现金属物体的无触点检测，具有稳定可靠的性能表现，可广泛应用于机械定位、流水线计数、液位信号检测等领域。其设计兼顾实用性与耐用性，外壳采用ABS材质，检测面同样为ABS保护构造，防护等级达到IP67，能够适应多种工业环境需求。1
技术特点
该接近开关的检测距离为20mm（±10%），设定距离范围为0-7mm，滞后距离小于检测距离的10%。产品对磁性金属具有标准检测能力，当铁质物体（65×65×1mm标准检测体）进入感应范围时，开关会迅速响应。其响应频率在直流供电时为0.5kHz，交流供电时为25Hz，能够满足不同工况下的快速检测需求。电源电压支持宽范围输入，直流型为12-24V（6-36V），交流型为110-220V（36-250V），具备良好的电压适应性。12
功能优势
SD-3020C提供多种输出配置选择，包括直流三线制的NPN/PNP常开/常闭型号（如SD-3020A/B/C/D），以及直流二线制（SD-3020AL/BL）和交流二线制（SD-2020A/B）等型号。产品采用高频振荡器原理工作，当金属目标接近感应区域时会产生涡流效应，通过振荡衰减变化触发开关信号，实现精确的位置检测。这种工作方式避免了机械接触带来的磨损，延长了使用寿命，同时无火花设计也提升了安全性。812
应用场景
该产品特别适合在机床限位、自动包装线定位、输送带检测等场景中使用。在冶金、矿山、塑料加工等行业中，可有效完成物体存在检测、行程控制等功能。其耐温范围为-30℃至+65℃，适应多数工业环境温度变化，湿度范围35-95%RH不结冰条件下可稳定工作。产品结构设计考虑了安装便利性，圆盘式外形便于固定，且检测面设计减少了误触发可能。2126
产品英文介绍
The SD-3020C is an inductive proximity sensor with disc-type configuration, designed for non-contact detection of metallic objects in industrial automation systems. Operating on electromagnetic induction principle, it offers reliable metal detection within 20mm sensing range (±10% tolerance), with adjustable actuation distance up to 7mm. The sensor demonstrates consistent performance when detecting standard ferrous targets (65×65×1mm iron plate), featuring fast response frequency of 0.5kHz (DC) or 25Hz (AC).1
Multiple output configurations are available including 3-wire DC (NPN/PNP NO/NC) and 2-wire DC/AC versions. The housing and sensing face utilize durable ABS material with IP67 protection rating, ensuring resistance against dust and water ingress. Wide voltage compatibility covers 6-36VDC or 36-250VAC operation. The contactless switching mechanism eliminates mechanical wear, while the optimized oscillation circuit provides stable detection unaffected by surface conditions of targets. Ideal for position control, object counting and safety monitoring in manufacturing equipment.214
This sensor maintains detection consistency across -30°C to +65°C temperature range and 35-95% humidity environments. The compact disc-shaped design facilitates installation in confined spaces, with threaded mounting options for secure fixation. Typical applications include CNC machine tool positioning, conveyor belt monitoring, and automated production line control systems across metallurgy, mining and packaging industries. The product s maintenance-free operation and consistent output characteristics make it a practical solution for industrial sensing requirements.2628
