接近开关 防爆
防爆接近开关产品介绍（中英文）
防爆接近开关是一种专为易燃易爆环境设计的非接触式位置传感器，能够在石油、化工、煤矿等危险场所安全可靠地工作。该产品采用无触点设计，通过电磁感应原理检测金属物体的接近，无需机械接触即可输出开关信号。其外壳通常采用铝合金或不锈钢材质，具备防水、防腐蚀、耐高温等特性，防护等级可达IP66/IP67，适用于-20℃至+75℃的恶劣环境。产品类型包括电感式、电容式、磁性式等，检测距离从1mm至30mm不等，响应频率高，寿命长，可广泛应用于机械设备定位、流水线计数、阀门状态监测等场景。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
产品技术特点（中英文）
该产品采用一体化放大电路设计，具有浪涌保护和极性反接保护功能，工作电压覆盖DC10-30V或AC220V。独特的密封结构使其可在水中或高粉尘环境下稳定工作，部分型号尾部配有灵敏度调节器以精确控制检测距离。磁性接近开关采用永磁体触发机制，适用于高温或存在油污的工况；电感式型号则对金属物体具有更高检测精度。所有产品均通过严格测试，确保在机械振动和冲击条件下保持稳定输出。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
应用领域说明（中英文）
在石油开采平台和化工厂中，该产品用于监测管道阀门开闭状态；在煤矿输送系统里检测设备极限位置；食品加工行业则利用其卫生型设计进行包装机械控制。其他典型应用包括电梯平层控制、自动门感应、车辆定位及安全区域报警等。产品安装方式灵活，可选用圆柱形、方形或分离式结构，接线方式涵盖两线制、三线制NPN/PNP输出，便于集成到PLC控制系统。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
