【GA-3 Magnetic Proximity Switch Product Introduction (English Version)】
The GA-3 series magnetic proximity switch is a high-sensitivity detection device specifically engineered for industrial automation applications. Utilizing non-contact magnetic field sensing technology, it achieves precise detection of metallic objects. With optimized magnetic circuit design and enhanced signal processing modules, this product delivers consistent performance in challenging working environments, making it ideal for equipment positioning, safety interlock systems, and automated production lines.
Encased in weather-resistant engineering plastic with IP67-rated sealing, the switch maintains reliable operation within a temperature range of -25℃ to +85℃, offering robust protection against dust, oil contaminants, and moisture exposure. The curved magnetic induction surface expands detection coverage by 30% compared to conventional models, achieving a maximum sensing distance of 25mm. A dual-color LED status indicator with 360° visibility enables instant operational status monitoring for field technicians.
Available in both NPN and PNP output configurations, the device supports DC 10-30V wide voltage input to accommodate diverse control systems. Core components have undergone rigorous 2 million-cycle endurance testing, while silver-alloy plated contacts ensure reliable electrical connectivity under frequent switching conditions. Flexible mounting options include flush or non-flush installations, with standard M12/M18 threaded housings compatible with mainstream industrial interfaces.
Typical applications encompass injection molding machine mold positioning, AGV navigation sensing, hydraulic cylinder stroke control, and automated warehouse access systems. Compared to mechanical limit switches, this contactless design eliminates physical wear issues, particularly suitable for high-speed moving component detection. Advanced electromagnetic interference (EMI) suppression circuitry ensures stable operation near frequency converters, motors, and other high-noise equipment.
Customization services are available for partners, including adjustable cable lengths, connector types, and housing colors. All products undergo 72-hour accelerated aging tests prior to shipment, backed by a three-year warranty. Our technical support team stands ready to provide tailored selection guidance and system integration solutions.
