小型接近開關產品介紹
小型接近開關是一種緊湊型傳感器，采用非接觸式檢測技術，適用于空間受限的工業自動化場景。其方形或微型設計便于安裝在狹窄區域，可檢測金屬或非金屬物體的接近狀態，廣泛應用于機械設備定位、流水線計數及安全防護。外殼采用高強度塑料或金屬材質，具備防水防塵性能（如IP67等級），適應惡劣環境。直流或交流供電可選，輸出信號類型包括NPN/PNP常開/常閉，響應速度快（毫秒級），工作距離從2mm至50mm不等。例如，扁平小方形接近開關通過電磁感應原理實現精準檢測，而電容式型號可識別液體或粉末材料。1310
Small Proximity Switch Introduction
Small proximity switches are compact sensors designed for non-contact detection in confined industrial spaces. Their square or miniature form factor allows easy integration into tight areas, ideal for position sensing, object counting, and safety applications. Constructed with durable plastic or metal housings, these switches offer resistance to water and dust (e.g., IP67-rated), ensuring reliability in harsh conditions. Available in DC/AC power options with NPN/PNP NO/NC outputs, they feature fast response times (millisecond-level) and sensing ranges from 2mm to 50mm. For instance, flat rectangular models utilize electromagnetic induction for metal detection, while capacitive variants can sense non-metallic materials like liquids. 2611
方形接近開關與門磁開關特點
方形接近開關以其模塊化設計和高兼容性成為自動化控制系統的核心組件。例如，JDD-A-AB50型號通過高頻磁場變化觸發信號，支持PLC或繼電器控制，適用于高速生產線。門磁開關則采用干簧管技術，當磁體靠近時觸點閉合，常用于門窗安防或智能家居。其常開/常閉型可選，工作電壓覆蓋12V至250V，安裝靈活且壽命長。部分產品如RX-PS系列具備耐高溫特性，適用于工業或戶外場景。71214
Square Proximity & Magnetic Door Switches
Square proximity switches excel in modularity and integration, such as the JDD-A-AB50 model, which triggers via electromagnetic field distortion for PLC-based automation. Magnetic door switches employ reed contacts activated by magnets, widely used in security systems and smart homes. With NO/NC configurations and 12V–250V voltage ranges, they offer flexible mounting and extended durability. Products like the RX-PS series withstand high temperatures, suitable for industrial gates or outdoor enclosures. These switches ensure reliable performance in both residential and commercial settings without mechanical wear. 91523
應用場景與優勢
小型及方形接近開關適用于電梯定位、包裝機械和液位檢測，其非接觸式設計避免磨損，提升設備壽命。門磁開關在智能鎖和倉儲管理中實現無接觸觸發，如檢測貨架狀態。優勢包括抗干擾性強、安裝簡便（如螺紋或貼面固定），以及多材質檢測能力（金屬/塑料/液體）。例如，電容式接近開關可穿透非金屬容器監測內容物，而電感式型號專用于金屬目標。4817
Applications & Benefits
These switches are ideal for elevator positioning, packaging machinery, and liquid-level monitoring, with contactless operation reducing maintenance. Magnetic door switches enable touchless activation in smart locks or inventory systems, such as tracking shelf status. Key advantages include interference resistance, easy installation (threaded or surface-mount), and multi-material compatibility (metals/plastics/liquids). Capacitive variants detect contents through non-metallic barriers, while inductive types target metal objects exclusively. 51316
