Product Overview
The LJC30A3-H-Z/AX capacitive proximity switch is a high-performance non-contact sensor based on capacitive sensing technology. It detects a wide range of dielectric materials, such as metals, non-metals, liquids, and powders. The device consists of an oscillator and signal processing circuit, where the capacitance change triggered by target proximity enables precise position or presence detection. With a compact M30 threaded housing and IP67 protection, it is suitable for harsh industrial environments with dust or moisture.
Key Features
- Versatility: Compatible with conductive, insulating, and liquid targets, ideal for logistics, food processing, and chemical industries.
- Reliability: Temperature compensation ensures stable operation within -25℃~+70℃.
- Flexibility: DC 3-wire (NPN/PNP) output options for seamless integration with control systems.
- Durability: Contactless design eliminates mechanical wear, extending service life.2710
技術(shù)原理
電容式接近開(kāi)關(guān)的感應(yīng)電極與目標(biāo)物體形成等效電容，當(dāng)物體接近時(shí)介電常數(shù)變化導(dǎo)致振蕩電路狀態(tài)改變，經(jīng)放大電路處理后輸出開(kāi)關(guān)信號(hào)。此設(shè)計(jì)無(wú)需物理接觸，避免了傳統(tǒng)開(kāi)關(guān)的機(jī)械損耗。產(chǎn)品支持靈敏度調(diào)節(jié)，通過(guò)電位器可適配不同介電常數(shù)的檢測(cè)目標(biāo)。典型應(yīng)用包括流水線物料檢測(cè)、液位監(jiān)控及自動(dòng)化設(shè)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(yīng)用場(chǎng)景
適用于包裝機(jī)械的缺料報(bào)警、化工罐體液位控制、木材加工中的非金屬檢測(cè)等場(chǎng)景。例如，在食品生產(chǎn)線中可檢測(cè)塑料瓶蓋是否存在；在建材行業(yè)用于監(jiān)控石膏粉料倉(cāng)的填充狀態(tài)。其抗干擾設(shè)計(jì)和堅(jiān)固外殼確保在振動(dòng)、電磁噪聲環(huán)境中可靠運(yùn)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
