【Product Description in English】
The SN04-P inductive proximity sensor is a high-performance non-contact detection device specifically engineered for industrial automation systems. Operating on electromagnetic induction principle, this sensor reliably detects metallic targets within 4mm range while maintaining stable performance in challenging working conditions. Its hybrid housing combines engineering-grade polymer with stainless steel components, achieving IP67 protection level that effectively resists dust ingress and high-pressure water jets, with operational temperature range spanning from -25℃ to +70℃.
Equipped with imported sensing core components, the sensor demonstrates exceptional electromagnetic interference resistance, maintaining detection error rate below 0.3% in strong electromagnetic environments. The compact cylindrical design (Φ18×50mm) allows versatile installation options through standard M18 threaded mounting. Featuring 3-wire NPN/PNP dual-output configuration, it seamlessly integrates with mainstream PLC systems, delivering sub-1ms response speed ideal for high-speed production line applications.
Key technological advantages include: 1) Intelligent temperature compensation ensuring ±0.1mm detection accuracy within ±20℃ ambient variation; 2) Multi-color LED indicator enabling 360° operational status monitoring; 3) Fully potted epoxy construction providing superior vibration resistance. The product has passed 2 million mechanical cycle tests, with specially alloyed contacts ensuring long-term reliability under frequent switching conditions.
Typical applications encompass automated warehouse sorting systems, CNC machine tool positioning, and packaging machinery motion detection. Supporting 12/24V DC wide voltage input, the sensor delivers up to 300mA output current for direct control of medium-power actuators. Each unit undergoes 72-hour aging test before shipment, backed by 2-year warranty and professional technical support services.
