Explosion-proof Proximity Switch & Limit Switch Product Introduction
I. Explosion-proof Proximity Switch
This contactless detection device is engineered for hazardous environments containing combustible substances. Utilizing electromagnetic field technology, it reliably identifies metallic targets within defined sensing ranges while eliminating spark generation risks. The triple-sealed enclosure constructed from impact-resistant alloy ensures operational integrity under extreme conditions (-40℃ to +80℃). With multiple detection distance options and universal power supply compatibility, it features vibration-proof terminals and corrosion-resistant surface treatment. Typical installations include automated material handling systems in petrochemical plants, coal processing facilities, and explosive powder production lines where ignition prevention is critical.
II. Explosion-proof Limit Switch
Designed for precise mechanical position control in explosive atmospheres, this safety switch employs fully isolated contact mechanisms to ensure spark-free operation. The modular construction allows flexible adjustment of actuator arm length and contact configuration. Die-cast aluminum housing with internal arc-quenching chambers provides reliable protection against gas/dust penetration. Silver-cadmium oxide contacts deliver stable electrical performance through repetitive operations. Adjustable roller lever actuators enable accurate travel setting, suitable for both linear and rotational motion monitoring. Widely implemented in explosion-protected crane systems, safety door interlocks, and hazardous area conveyor controls, its rugged design withstands continuous mechanical stress and environmental challenges.
