接近開(kāi)關(guān) 防爆
防爆接近開(kāi)關(guān)產(chǎn)品介紹（中英文）
防爆接近開(kāi)關(guān)是一種專(zhuān)為易燃易爆環(huán)境設(shè)計(jì)的非接觸式位置傳感器，能夠在石油、化工、煤礦等危險(xiǎn)場(chǎng)所安全可靠地工作。該產(chǎn)品采用無(wú)觸點(diǎn)設(shè)計(jì)，通過(guò)電磁感應(yīng)原理檢測(cè)金屬物體的接近，無(wú)需機(jī)械接觸即可輸出開(kāi)關(guān)信號(hào)。其外殼通常采用鋁合金或不銹鋼材質(zhì)，具備防水、防腐蝕、耐高溫等特性，防護(hù)等級(jí)可達(dá)IP66/IP67，適用于-20℃至+75℃的惡劣環(huán)境。產(chǎn)品類(lèi)型包括電感式、電容式、磁性式等，檢測(cè)距離從1mm至30mm不等，響應(yīng)頻率高，壽命長(zhǎng)，可廣泛應(yīng)用于機(jī)械設(shè)備定位、流水線(xiàn)計(jì)數(shù)、閥門(mén)狀態(tài)監(jiān)測(cè)等場(chǎng)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(chǎn)品技術(shù)特點(diǎn)（中英文）
該產(chǎn)品采用一體化放大電路設(shè)計(jì)，具有浪涌保護(hù)和極性反接保護(hù)功能，工作電壓覆蓋DC10-30V或AC220V。獨(dú)特的密封結(jié)構(gòu)使其可在水中或高粉塵環(huán)境下穩(wěn)定工作，部分型號(hào)尾部配有靈敏度調(diào)節(jié)器以精確控制檢測(cè)距離。磁性接近開(kāi)關(guān)采用永磁體觸發(fā)機(jī)制，適用于高溫或存在油污的工況；電感式型號(hào)則對(duì)金屬物體具有更高檢測(cè)精度。所有產(chǎn)品均通過(guò)嚴(yán)格測(cè)試，確保在機(jī)械振動(dòng)和沖擊條件下保持穩(wěn)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(yīng)用領(lǐng)域說(shuō)明（中英文）
在石油開(kāi)采平臺(tái)和化工廠(chǎng)中，該產(chǎn)品用于監(jiān)測(cè)管道閥門(mén)開(kāi)閉狀態(tài)；在煤礦輸送系統(tǒng)里檢測(cè)設(shè)備極限位置；食品加工行業(yè)則利用其衛(wèi)生型設(shè)計(jì)進(jìn)行包裝機(jī)械控制。其他典型應(yīng)用包括電梯平層控制、自動(dòng)門(mén)感應(yīng)、車(chē)輛定位及安全區(qū)域報(bào)警等。產(chǎn)品安裝方式靈活，可選用圓柱形、方形或分離式結(jié)構(gòu)，接線(xiàn)方式涵蓋兩線(xiàn)制、三線(xiàn)制NPN/PNP輸出，便于集成到PLC控制系統(tǒng)。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
