奧托尼克斯型電容式感應接近開關CR18-8DN
產品概述
奧托尼克斯CR18-8DN是一款高性能電容式接近開關，采用非接觸式檢測技術，適用于工業自動化領域的多種應用場景。該產品能夠穩定檢測金屬、液體、塑料、玻璃等不同介電常數的物體，內置靈敏度調節旋鈕，用戶可根據實際需求靈活調整檢測距離。其圓柱形設計（M18×1螺紋）便于安裝，防護等級達到IP66，可在-25℃至70℃的寬溫環境下可靠工作。269
技術特點
CR18-8DN基于電容感應原理，通過測量物體與傳感器間介電常數的變化觸發信號輸出。其檢測距離為8mm（標準條件下），響應頻率為50Hz，支持DC10-30V寬電壓輸入，消耗電流低于15mA。產品采用三線制NPN輸出，配備動作指示燈，便于現場調試。強化電纜設計提升了抗彎曲性能，延長了使用壽命。此外，內置的過壓、反接保護電路增強了設備穩定性。2611
應用領域
該傳感器廣泛應用于物料檢測、液位控制、設備定位等場景。例如在包裝機械中檢測透明薄膜，在食品行業監控容器液位，或在電子產線識別非金屬元件。其通用性設計使其能替代傳統機械開關，減少磨損并提升系統效率。1016
Product Overview
The Autonics CR18-8DN is a capacitive proximity sensor designed for non-contact detection in industrial automation. It reliably identifies objects with varying dielectric constants, including metals, liquids, and plastics, thanks to its adjustable sensitivity via a built-in potentiometer. The cylindrical housing (M18×1 threaded) ensures easy mounting, while IP66 protection and an operating temperature range of -25℃ to 70℃ guarantee durability in harsh environments.919
Key Features
Operating on capacitive sensing technology, the CR18-8DN triggers signals by detecting changes in dielectric properties between the target and sensor. It offers an 8mm sensing range (under standard conditions), 50Hz response frequency, and supports 10-30VDC power input with low current consumption (<15mA). The 3-wire NPN output includes an operation indicator for real-time status monitoring. Reinforced cable construction enhances flexibility and service life, while integrated overvoltage and reverse polarity protection ensures stable performance.611
Applications
Ideal for material presence checks, liquid level control, and position sensing, this sensor is widely used in packaging machines, food processing equipment, and electronic assembly lines. Its non-mechanical design reduces maintenance needs and improves operational efficiency compared to traditional switches.1016
