感应磁簧接近开关传感器
产品概述
感应磁簧接近开关传感器是一种基于磁感应原理的非接触式位置检测装置,通过磁场信号控制电路通断,实现精准的位置感知与信号输出。其核心部件为密封于惰性气体环境中的磁簧开关(干簧管),当外部永磁体靠近时,磁力驱动簧片吸合或断开,触发开关动作。该产品采用耐磨损的ABS或铜制外壳,具备防水、防尘、耐高温及抗腐蚀特性,适用于工业自动化、流体控制、安防系统等场景。1710
核心特点
- 高可靠性设计:磁簧开关无机械磨损,寿命可达百万次以上,密封结构确保在潮湿、油污或腐蚀性环境中稳定工作。
- 灵活安装:提供圆柱形、方形等多种外形尺寸,支持螺丝固定或嵌入式安装,适配不同设备空间需求。
- 无源操作:无需额外供电即可工作,直接串联至控制回路,简化布线并降低能耗。
- 兼容性强:支持常开(NO)、常闭(NC)及双稳态输出模式,可检测磁性物体或通过铁质导体间接感应。3912
应用领域
广泛应用于自动化设备行程控制(如气缸位置检测)、液位监测(搭配浮球磁铁)、门窗安全报警系统、家用电器(咖啡机、洗衣机)及汽车电子等领域。其非接触式检测方式可替代传统机械限位开关,提升系统响应速度与耐久性。111721
Product Overview
The magnetic reed proximity sensor is a non-contact position detection device based on magnetic induction principles. It utilizes a hermetically sealed reed switch (dry reed tube) activated by external magnetic fields to control circuit switching. Encased in durable ABS or brass housing, it offers resistance to water, dust, high temperatures, and corrosion, making it ideal for industrial automation, fluid control, and security systems.1710
Key Features
- Reliable Performance: The reed switch eliminates mechanical wear, ensuring over a million operations, while sealed construction guarantees stability in harsh environments.
- Versatile Installation: Available in cylindrical or rectangular designs with screw-fixing or embedded mounting options for flexible integration.
- Self-Powered Operation: Requires no external power supply, simplifying wiring and reducing energy consumption.
- Multi-Mode Output: Supports NO, NC, and bistable configurations, compatible with direct magnetic targets or indirect detection via ferrous materials.3912
Applications
Commonly used in automated equipment (e.g., cylinder position sensing), liquid level monitoring (with float magnets), door/window security alarms, household appliances (e.g., coffee makers), and automotive electronics. Its non-contact mechanism enhances response speed and longevity compared to mechanical limit switches.111721
