防爆接近開關產品介紹（中英文）
防爆接近開關是一種專為易燃易爆環境設計的非接觸式位置傳感器，能夠在石油、化工、煤礦等危險場所安全可靠地工作。該產品采用無觸點設計，通過電磁感應原理檢測金屬物體的接近，無需機械接觸即可輸出開關信號。其外殼通常采用鋁合金或不銹鋼材質，具備防水、防腐蝕、耐高溫等特性，防護等級可達IP66/IP67，適用于-20℃至+75℃的惡劣環境。產品類型包括電感式、電容式、磁性式等，檢測距離從1mm至30mm不等，響應頻率高，壽命長，可廣泛應用于機械設備定位、流水線計數、閥門狀態監測等場景。1520
Explosion-proof proximity switches are non-contact position sensors specifically engineered for hazardous environments with flammable gases or dust. These devices utilize electromagnetic induction to detect metal objects without physical contact, ensuring spark-free operation in oil refineries, chemical plants, and mining facilities. Featuring robust housings made of aluminum alloy or stainless steel, they offer resistance to water, corrosion, and high temperatures (up to 150°C for certain models). With detection ranges spanning 1mm to 30mm and high switching frequencies, they provide reliable performance in position control, production line counting, and equipment status monitoring. The product series includes inductive, capacitive, and magnetic types to accommodate diverse industrial applications. 21217
產品技術特點（中英文）
該產品采用一體化放大電路設計，具有浪涌保護和極性反接保護功能，工作電壓覆蓋DC10-30V或AC220V。獨特的密封結構使其可在水中或高粉塵環境下穩定工作，部分型號尾部配有靈敏度調節器以精確控制檢測距離。磁性接近開關采用永磁體觸發機制，適用于高溫或存在油污的工況；電感式型號則對金屬物體具有更高檢測精度。所有產品均通過嚴格測試，確保在機械振動和沖擊條件下保持穩定輸出。81118
Technologically, these switches integrate amplifier circuits with surge protection and reverse polarity safeguards, supporting both DC10-30V and AC220V power inputs. Their hermetic sealing enables stable operation underwater or in dusty conditions, with some models featuring adjustable sensitivity controls. Magnetic variants employ permanent magnet actuation for high-temperature or greasy environments, while inductive types deliver precise metal detection. Rigorous testing validates their performance under mechanical vibration (10-55Hz) and shock (1,000m/s²), maintaining consistent signal output in demanding industrial scenarios. 3922
應用領域說明（中英文）
在石油開采平臺和化工廠中，該產品用于監測管道閥門開閉狀態；在煤礦輸送系統里檢測設備極限位置；食品加工行業則利用其衛生型設計進行包裝機械控制。其他典型應用包括電梯平層控制、自動門感應、車輛定位及安全區域報警等。產品安裝方式靈活，可選用圓柱形、方形或分離式結構，接線方式涵蓋兩線制、三線制NPN/PNP輸出，便于集成到PLC控制系統。61421
These switches serve critical functions across industries: monitoring pipeline valve positions in oil platforms, detecting equipment limits in coal conveyor systems, and controlling packaging machinery in food processing with hygienic designs. Additional applications encompass elevator leveling, automatic door sensing, vehicle positioning, and safety zone alarms. Offering flexible mounting options (cylindrical, rectangular, or separable configurations) and wiring choices (2-wire or 3-wire NPN/PNP outputs), they seamlessly integrate with PLC control systems. The product line includes flush-mounted and non-flush models to accommodate different installation requirements. 71319
