【Product Introduction in English】
The NC-20CO square-flat Hall proximity sensor is a magnetic sensing device developed based on the Hall effect principle, specifically designed for precise position detection in industrial automation, mechanical equipment, and electronic control systems. Featuring a three-wire NPN transistor output configuration with normally open (NO) contacts, this 24V DC operated device delivers rapid response, strong anti-interference capability, and extended service life. Its compact square-flat housing (20×20×8mm typical dimensions) optimizes space utilization for equipment with strict size requirements.
Equipped with a high-sensitivity Hall element, the sensor achieves non-contact detection of magnetic targets within a 0-10mm range. Industrial-grade encapsulation materials ensure reliable operation across a broad temperature range from -25℃ to +85℃, while providing basic protection against dust and oil contamination. The integrated circuit design incorporates reverse polarity protection and overload protection, effectively minimizing failure risks caused by wiring errors or voltage fluctuations.
Key performance highlights include sub-1ms response time for capturing instantaneous positional changes of moving components, and low power consumption with operational current below 15mA. The built-in LED status indicator enables real-time monitoring of working conditions. Utilizing NPN transistor NO output mode, the sensor automatically conducts upon detecting valid magnetic fields, ensuring seamless compatibility with mainstream PLC control systems. The flat-profile housing with M18 threaded mounting holes supports versatile installation methods including panel embedding and bracket fixation.
Typical applications encompass cylinder position feedback in automated production lines, material presence detection on conveyor systems, and safety door status monitoring for industrial machinery. In automotive manufacturing, it serves as positioning sensor for robotic welding clamps, while in logistics sorting systems it enables package location identification. The product also integrates effectively into smart home devices as door/window contact sensors. Rigorous aging tests and vibration resistance verification guarantee consistent detection accuracy under continuous operation conditions.
Structural advantages include optimized magnetic circuit design for enhanced directional sensitivity, reinforced housing corners for impact resistance, and color-coded wiring terminals (brown: +24V, blue: GND, black: signal output) simplifying installation procedures. Maintenance-friendly design allows for quick module replacement without disassembling entire equipment assemblies.
