APL420N 防爆接近開關(guān) 感應(yīng)接近式隔爆開關(guān)
產(chǎn)品概述
APL420N防爆接近開關(guān)是一款專為工業(yè)自動化控制系統(tǒng)設(shè)計的感應(yīng)式隔爆開關(guān)，適用于檢測閥門狀態(tài)并輸出開關(guān)量信號。該產(chǎn)品采用非接觸式檢測技術(shù)，通過電感式傳感器感知金屬目標的位置變化，實現(xiàn)高精度信號反饋。外殼采用鋁合金材質(zhì)，表面經(jīng)過特殊處理，兼具美觀性與耐用性，適用于化工、石油、冶金等易燃易爆環(huán)境。其核心功能是將閥門的開啟或關(guān)閉狀態(tài)轉(zhuǎn)換為電信號，便于遠程監(jiān)控或程序控制。
技術(shù)特點
APL420N內(nèi)置高性能電感式接近傳感器，響應(yīng)速度快且壽命長，無需機械接觸即可完成檢測，避免磨損問題。產(chǎn)品支持多種安裝方式，配備不銹鋼主軸和符合行業(yè)標準的安裝支架，可適配不同規(guī)格的氣動執(zhí)行器。防護性能優(yōu)異，能在惡劣環(huán)境中穩(wěn)定工作，如粉塵、潮濕或腐蝕性氣體場合。開關(guān)位置可通過外部指示器清晰辨識，并支持快速調(diào)整凸輪位置，便于現(xiàn)場調(diào)試。
應(yīng)用場景
該產(chǎn)品廣泛應(yīng)用于閥門位置反饋、自動化流水線定位、機械設(shè)備限位控制等場景。例如，在化工管道中用于監(jiān)測球閥或蝶閥的開閉狀態(tài)，或在輸送系統(tǒng)中檢測金屬部件的位置。其模塊化設(shè)計允許用戶選配不同感應(yīng)距離和輸出形式的傳感器，滿足多樣化需求。
Product Overview
The APL420N explosion-proof proximity switch is an inductive-type hazardous area switch designed for industrial automation control systems. It detects valve positions and outputs switching signals without physical contact. The housing is made of aluminum alloy with a robust finish, suitable for flammable and explosive environments such as chemical plants and oil refineries. Its primary function is converting valve states into electrical signals for remote monitoring or programmatic control.
Key Features
Equipped with an advanced inductive sensor, the APL420N offers fast response and long service life. The non-contact detection mechanism eliminates mechanical wear. It features versatile mounting options, stainless steel shafts, and industry-compliant brackets for easy integration with pneumatic actuators. The switch excels in harsh conditions, including dusty, humid, or corrosive atmospheres, with clear visual position indicators and tool-free cam adjustment for field calibration.
Applications
Ideal for valve position feedback, conveyor belt positioning, and machinery limit control, this product adapts to diverse industrial needs. For instance, it monitors ball or butterfly valve status in pipelines or detects metal components in automated systems. Modular design allows customization of sensing ranges and output configurations.
