該系列產(chǎn)品可廣泛應(yīng)用于注塑機(jī)械定位、傳送帶物料檢測、自動包裝設(shè)備、立體倉儲系統(tǒng)及電梯安全控制等領(lǐng)域。通過優(yōu)化電磁兼容設(shè)計(jì)，設(shè)備在變頻器、電機(jī)等強(qiáng)干擾源周邊仍可保持穩(wěn)定信號輸出。產(chǎn)品出廠前經(jīng)過多道質(zhì)量檢驗(yàn)流程，內(nèi)部組件采用耐老化材料以延長使用壽命。
QL-1805NA/QiSheng QL-1805 Proximity Switch Product Introduction (English Version)
The QL-1805NA and QL-1805 QiSheng proximity switches are high-performance non-contact detection devices engineered for industrial automation scenarios. Utilizing proven induction technology, these sensors reliably detect the approach status of metallic or non-metallic objects, suitable for position detection, counting control, and safety protection in complex environments. The compact housing design (typical dimensions Φ18×50mm) ensures easy installation and integration, with a composite construction of engineering plastic and metal alloy that balances mechanical durability and environmental adaptability.
Key technical advantages include: 1) Precise sensing capability with adjustable detection distance up to 8mm (material-dependent), supporting rapid response frequency for dynamic monitoring; 2) Broad voltage compatibility (DC 10-30V) accommodates diverse control systems, available in both NPN and PNP output configurations; 3) Integrated reverse polarity protection and overload prevention circuits, combined with IP67 protection rating, ensure reliable operation in dusty, greasy, or temporarily submerged conditions; 4) Operating temperature range from -25℃ to +70℃ maintains stability in chilled storage facilities and high-temperature workshops.
Ideal for injection molding machine positioning, conveyor belt material detection, automated packaging systems, intelligent warehousing solutions, and elevator safety controls. Enhanced electromagnetic compatibility design minimizes signal interference near frequency converters and motor drives. Each unit undergoes multiple quality verification procedures during manufacturing, with internal components constructed from anti-aging materials to optimize service life.
