防爆接近开关产品介绍
防爆接近开关是一种无需机械接触即可检测物体位置的传感器装置，适用于易燃易爆环境。其采用电感式、电容式或磁感应原理，当金属或非金属物体接近感应面时，开关自动触发信号输出。产品具备防水、防尘、耐腐蚀特性，适用于化工、石油、煤矿等危险场所。常见型号如SEBND系列，采用不锈钢外壳，感应距离可调，支持常开/常闭输出。高温型可在150℃环境下稳定工作，部分型号内置浪涌保护和电源反接保护功能，确保长期可靠性。1610
Explosion-proof Proximity Switch
Explosion-proof proximity switches are non-contact sensors designed for hazardous environments. They detect objects via inductive, capacitive, or magnetic principles, triggering signals without physical contact. Constructed with stainless steel or alloy housings, these switches resist water, dust, and corrosion, ideal for oil refineries, chemical plants, and mining. Models like SEBND series offer adjustable sensing ranges (e.g., 2mm–15mm) and NO/NC outputs. High-temperature variants operate stably up to 150°C, with built-in surge protection and reverse polarity safeguards.
防爆开关产品介绍
防爆开关专为爆炸性气体或粉尘环境设计，包括倒顺开关、拉线开关、照明开关等类型。外壳采用铝合金压铸或工程塑料，表面静电喷塑处理，防护等级达IP65以上。产品结构紧凑，具备过载、短路保护功能，适用于石油平台、化工厂等场所。例如，Bulgin品牌开关采用无火花触点设计，支持瞬时启动和频繁操作，寿命长达万次以上。部分型号集成指示灯或电流表，便于现场监控。161317
Explosion-proof Switch
These switches are engineered for gas/dust explosive conditions, featuring robust aluminum alloy or plastic enclosures with IP65+ protection. Types include toggle, pull-cord, and lighting switches, all with overload/short-circuit protection. Bulgin designs utilize spark-free contacts for safe ignition-prone areas, supporting high-frequency operation (10,000+ cycles). Some models integrate indicators or ammeters for real-time status monitoring in oil rigs or pharmaceutical facilities.
防爆行程开关产品介绍
防爆行程开关通过机械位移控制电路通断，适用于卷扬机、输送带等设备的限位保护。外壳为铸铝合金或304不锈钢，内装LX19微动开关，支持左/右摇臂、滚轮柱塞等多种触发方式。工作电压覆盖AC220V-380V，适应温度范围-25℃至+55℃，防护等级IP54/IP65。典型应用包括石化、军工等场景，部分型号具备记忆功能，可记录动作状态。111221
Explosion-proof Limit Switch
Used for position control in hoists or conveyors, these limit switches employ LX19 microswitches inside alloy/steel housings. Actuation modes include roller plunger or lever arms, compatible with 220V–380V AC. Operating temperatures span -25°C to +55°C, with IP54/IP65 ratings. Memory-type variants retain actuation status, suitable for chemical plants and military applications.
防爆启动开关产品介绍
防爆启动开关用于电机、泵类的远程启停控制，复合型结构整合隔爆腔与增安腔，内装断路器、接触器等元件。支持挂式或落地安装，额定电流10A-250A，电压至1140V。特点包括模块化设计、防水密封圈及不锈钢紧固件，适用于变频器、PLC系统联动。例如，BQC系列防爆电磁启动器可正反转控制，适应-20℃至+40℃环境。152327
Explosion-proof Starter Switch
These switches enable remote motor/pump control, combining flameproof and increased safety compartments. Modular designs accommodate breakers or contactors (10A–250A, up to 1140V), with wall/floor mounting options. Features include IP55 sealing and stainless hardware for PLC integration. BQC series supports forward/reverse operation in -20°C to +40°C conditions.
