- Durability: Contactless design eliminates mechanical wear, extending service life.2710
技術原理
電容式接近開關的感應電極與目標物體形成等效電容，當物體接近時介電常數(shù)變化導致振蕩電路狀態(tài)改變，經放大電路處理后輸出開關信號。此設計無需物理接觸，避免了傳統(tǒng)開關的機械損耗。產品支持靈敏度調節(jié)，通過電位器可適配不同介電常數(shù)的檢測目標。典型應用包括流水線物料檢測、液位監(jiān)控及自動化設備定位。921
Technical Principle
The switch’s sensing electrode and target object form an equivalent capacitor. As the target approaches, dielectric constant variation alters the oscillator circuit state, generating a switch signal after amplification. This non-contact mechanism eliminates mechanical wear. An adjustable potentiometer allows sensitivity tuning for diverse dielectric materials. Typical applications include conveyor belt detection, liquid level monitoring, and automated positioning.1118
應用場景
適用于包裝機械的缺料報警、化工罐體液位控制、木材加工中的非金屬檢測等場景。例如，在食品生產線中可檢測塑料瓶蓋是否存在；在建材行業(yè)用于監(jiān)控石膏粉料倉的填充狀態(tài)。其抗干擾設計和堅固外殼確保在振動、電磁噪聲環(huán)境中可靠運行。416
Applications
Ideal for material absence alarms in packaging, liquid level control in chemical tanks, and non-metal detection in wood processing. For instance, it verifies plastic cap presence on food production lines or monitors gypsum powder levels in building material silos. Robust construction and anti-interference design ensure reliability in noisy or vibrating environments.2022
