滬工PNP常開電容式接近開關(guān)是一種先進(jìn)的非接觸式檢測(cè)裝置，廣泛應(yīng)用于工業(yè)自動(dòng)化領(lǐng)域。其感應(yīng)頭通常為一個(gè)圓形或方形平板電極，與振蕩電路的地線形成分布電容，當(dāng)有導(dǎo)體或其他介質(zhì)接近感應(yīng)頭時(shí)，電容量增大，振蕩器停止振蕩，經(jīng)整形放大器輸出電信號(hào)。這種接近開關(guān)可檢測(cè)金屬、非金屬和液體等多種物質(zhì)。

其主要特點(diǎn)包括：工作可靠、壽命長(zhǎng)、功耗低、復(fù)定位精度高、操作頻率高以及適應(yīng)惡劣的工作環(huán)境。產(chǎn)品采用黃銅鍍鎳外殼和ABS檢測(cè)面，防護(hù)等級(jí)達(dá)到IP67，能夠有效防塵防水。檢測(cè)距離一般為10mm或20mm，具體因型號(hào)而異，設(shè)定距離范圍在0-8mm或0-18mm之間。響應(yīng)頻率為DC0.5kHz，電源電壓范圍為DC12-24V，耐電壓可達(dá)AC1000V。

在工業(yè)生產(chǎn)中，該接近開關(guān)可用于物料檢測(cè)、液位控制、傳送帶物料計(jì)數(shù)等多種場(chǎng)景，幫助提高生產(chǎn)效率和自動(dòng)化水平。

English Introduction

The Hu Gong PNP normally open capacitive proximity switch is an advanced non-contact detection device widely used in the field of industrial automation. Its sensing head is usually a circular or square flat plate electrode, forming a distributed capacitor with the ground line of the oscillator circuit. When a conductor or other medium approaches the sensing head, the capacitance increases, the oscillator stops oscillating, and a telecommunication signal is output through a shaping amplifier. This type of proximity switch can detect a variety of substances, including metals, non-metals, and liquids.

The main features of this proximity switch include high reliability, long service life, low power consumption, high repositioning accuracy, high operating frequency, and the ability to adapt to harsh working environments. The product has a brass nickel-plated housing and an ABS sensing surface, with an IP67 protection rating, effectively preventing dust and water ingress. The detection distance is generally 10mm or 20mm, varying with the model, and the setting distance range is between 0-8mm or 0-18mm. The response frequency is DC0.5kHz, the power supply voltage range is DC12-24V, and the withstand voltage can reach AC1000V.

In industrial production, this proximity switch can be used in various scenarios such as material detection, liquid level control, and material counting on conveyor belts, helping to improve production efficiency and automation levels.
