【GMD-2A Magnetic Switch Product Introduction（English）】
The GMD-2A magnetic switch is an industrial-grade non-contact sensing device based on magnetic induction principles, suitable for automation equipment, machinery manufacturing, and safety protection systems. Utilizing electromagnetic induction technology, it achieves precise switching control through magnetic field detection, featuring rapid response and extended service life.
Constructed with a high-strength engineering plastic housing and internal magnetic-sensitive components, the product undergoes anti-corrosion surface treatment to withstand operating temperatures from -20℃ to +85℃. Its compact design enables easy integration into confined spaces, offering both rail-mounted and bolt-secured installation options for diverse industrial applications. Gold-plated contacts effectively reduce electrical resistance while ensuring stable signal transmission, compatible with DC 5-240V power inputs for mainstream control systems.
With an adjustable sensing range up to 15mm (actual performance varies by installation) and maximum operating frequency of 200Hz, this magnetic switch accommodates mid-to-high speed component detection. The IP67-rated sealed structure provides reliable protection against dust ingress and temporary water immersion. An integrated overload protection module automatically disconnects circuits during current anomalies to safeguard connected equipment.
Typical applications include position detection in automated production lines, elevator door interlock systems, limit protection for construction machinery, and status monitoring of logistics equipment. Compared to traditional mechanical switches, its contactless operation minimizes mechanical wear, while enhanced electromagnetic shielding design ensures stable performance in complex industrial environments.
