DZ73/磁性开关D-Z73

产品概述

D-Z73磁性开关是一款基于磁感应原理设计的工业级传感器装置，主要用于检测气缸活塞位置或机械运动行程。该产品采用干簧管技术，通过磁场信号实现电路通断控制，具有结构紧凑、响应灵敏的特点，适用于自动化设备中的位置检测与限位控制场景。17

技术原理

该开关的核心部件为密封玻璃管内的干簧管元件，内部封装两个铁质弹性簧片和惰性气体。当磁性物质靠近时，簧片在磁场作用下吸合导通电路；磁场消失后簧片依靠弹性自动复位断开。这种无源电子开关设计无需直接供电即可工作，支持DC/AC 5-240V宽电压范围，最大负载电流100mA。716

产品特性

D-Z73系列提供横向引出的直接安装结构，标准配置0.5米导线。产品采用抗干扰设计，能在工业环境中稳定工作，工作温度范围为-10°C至60°C，防护等级达到IP67。根据应用需求可选二线式（干簧管型）或三线式（NPN/PNP晶体管型）不同输出形式，满足多样化电气接口需求。810

应用领域

该磁性开关广泛应用于气动执行机构的位置反馈、自动化产线的行程检测、安防系统的门磁窗磁监测等领域。其兼容性设计可直接适配主流品牌气缸，在包装机械、印刷设备、汽车装配线等场景中实现精准的位置信号采集。117

Product Overview

The D-Z73 magnetic switch is an industrial-grade sensor device based on magnetic induction principle, primarily used for detecting cylinder piston positions or mechanical movement strokes. Utilizing reed switch technology, it controls circuit switching through magnetic field signals, featuring compact structure and responsive sensitivity for position detection in automated equipment.17

Technical Principle

At its core lies a hermetically sealed glass tube containing two ferrous elastic reeds and inert gas. When magnetic material approaches, the reeds magnetize and close the circuit; they automatically reset when the field disappears. This passive electronic switch operates without direct power supply, supporting wide voltage range of DC/AC 5-240V with 100mA maximum load current.716

Key Features

The D-Z73 series features side-exit direct mounting configuration with standard 0.5m cable. Its interference-resistant design ensures stable operation in industrial environments, with operating temperature range of -10°C to 60°C and IP67 protection rating. Available in 2-wire (reed type) or 3-wire (NPN/PNP transistor) variants to accommodate diverse electrical interfaces.810

Applications

This magnetic switch is widely implemented for position feedback in pneumatic actuators, stroke detection in automated production lines, and access monitoring in security systems. Its compatible design directly fits major cylinder brands, enabling precise position signaling in packaging machinery, printing equipment, automotive assembly lines and similar applications.117
