SN04-N接近開關NPN常開DC24V角柱型電感式傳感器直流三線
產品概述
SN04-N是一款電感式接近開關,采用角柱型設計,適用于工業自動化領域的金屬物體檢測。該傳感器通過直流三線NPN常開輸出方式工作,額定電壓為DC24V,能夠穩定檢測4mm范圍內的金屬目標。其緊湊的方形結構(18×18×36mm)和ABS塑料外殼使其適用于空間受限的安裝環境,同時具備抗干擾、耐腐蝕和防水特性。1616
技術特點
傳感器基于電感式檢測原理,當金屬物體接近感應區域時,內部LC振蕩器產生渦流效應,觸發開關動作,響應頻率達500Hz,適合高速檢測場景。支持6-36V寬電壓輸入,兼容不同工業電源環境。輸出為NPN三線常開型,可直接連接PLC或控制器,接線步驟簡單:先連接24V電源,再接入信號線與公共端。工作溫度范圍覆蓋-20℃~70℃,適應惡劣工況。61621
應用場景
廣泛應用于自動化生產線上的機械臂定位、傳送帶物料檢測、工裝夾具狀態監控等場景。也可用于物流分揀系統、圖書館設備管理及安全防護裝置,實現無接觸式位置檢測。其高重復精度和長壽命設計降低了設備維護頻率。61015
Product Overview
The SN04-N is an inductive proximity switch with a square-column design, designed for metal object detection in industrial automation. It operates via a DC three-wire NPN normally open (NO) output configuration at 24V, reliably detecting metal targets within a 4mm range. The compact dimensions (18×18×36mm) and ABS housing make it suitable for space-constrained installations, while offering resistance to interference, corrosion, and moisture.1716
Key Features
Utilizing inductive sensing technology, the switch activates when eddy currents generated by metallic objects alter the internal LC oscillator s parameters. With a 500Hz response frequency, it supports high-speed applications. The wide voltage input (6-36V) ensures compatibility with diverse power supplies. The NPN NO output simplifies integration with PLCs or control systems via a three-step wiring process: connect power, signal wire, and common terminal. Operating temperatures range from -20℃ to 70℃ for harsh environments.61221
Applications
Ideal for robotic arm positioning, conveyor belt material detection, and fixture status monitoring in automated production lines. Also used in logistics sorting systems, library equipment, and safety devices for contactless position sensing. Its high repeatability and durable design reduce maintenance needs.61020
