PR08-2DN接近开关/PR082DN
产品概述
PR08-2DN是一款电感式接近开关，采用直流12-24V供电，属于NPN常开型三线制传感器。其核心原理是通过电磁场感应金属物体的接近，当导电体进入检测范围时，内部振荡电路会产生涡流效应，从而触发开关动作。该产品设计紧凑，外壳直径8mm，检测距离为2mm，适用于工业自动化中的位置检测、计数和限位控制等场景。1616
技术特点
该接近开关采用非接触式检测方式，具有无机械磨损、响应速度快（频率可达0.5kHz）和长寿命的特点。产品内置电压波动保护和反接保护功能，工作温度范围覆盖-20℃至70℃，防护等级达到IP67，能适应潮湿、粉尘等工业环境。其标准配置2米导线，采用棕色（电源正）、蓝色（电源负）、黑色（信号输出）的接线方式，安装时支持齐平或非齐平式埋入。2818
应用领域
PR08-2DN广泛应用于机床、包装机械、纺织设备等自动化产线，可实现金属工件的到位检测、传送带物料计数、机械臂定位等功能。在电梯控制系统中可用于平层检测，在物流分拣设备中实现金属托盘识别。其稳定性能也适用于食品加工、印刷等需要防尘防溅的行业。6924
产品优势
相比机械式行程开关，该产品具有更高的定位精度和抗振动性能，操作频率可达800Hz。采用韩国奥托尼克斯（AUTONICS）原厂技术，传感器核心部件经过优化设计，确保在金属屑干扰环境下仍保持稳定检测。产品提供多种衍生型号可选，包括不同检测距离（1.5mm/2mm）和安装方式（标准型/加长螺纹型）。111926
English Product Introduction
The PR08-2DN is an inductive proximity sensor operating on 12-24VDC, featuring NPN normally-open configuration with 3-wire connection. This cylindrical sensor detects ferrous metal targets within 2mm range through electromagnetic field variation, generating eddy currents that alter oscillation parameters when metal objects approach. With compact M8 housing (8mm diameter), it suits space-constrained installations in industrial automation systems.116
Key Features
This non-contact switch eliminates mechanical wear with rapid response (500Hz switching frequency) and long service life. Built-in protections include reverse polarity safeguard (DC models) and voltage fluctuation resistance. The IP67-rated housing withstands dust and temporary immersion, operating reliably in -20°C to 70°C environments. Standard 2-meter cable follows color-coded wiring: brown (+V), blue (0V), and black (signal output). Both flush and non-flush mounting options are supported.2818
Typical Applications
Ideal for position sensing in CNC machines, conveyor systems, and robotic arms, the sensor performs metal part detection, object counting, and end-position control. Common implementations include elevator leveling, packaging line monitoring, and automated assembly verification. Its sealed construction also suits food processing equipment and printing machinery where liquid splash or powder exposure occurs.6924
Performance Advantages
Compared to mechanical limit switches, this solid-state device offers higher repeat accuracy (±0.1mm) and vibration resistance, supporting up to 800 operations per second. The optimized coil design from AUTONICS ensures stable performance even in environments with metal chips interference. Variants with different sensing ranges (1.5mm/2mm) and threaded lengths are available for flexible integration.111926
