The M12 Inductive Proximity Sensor DN12-4N1 PNP-NO DC10~30V 4mm is a high-performance non-contact inductive sensor designed for reliable metal object detection in industrial automation, manufacturing, robotics, conveyor systems, packaging machinery, CNC machines, and embedded control applications. Featuring a PNP Normally Open (NO) output, a sensing distance of 4mm, and a wide operating voltage range of 10V to 30V DC, this sensor provides accurate, fast, and maintenance-free detection of ferrous and conductive metal objects without physical contact. Its rugged M12 threaded metal housing ensures excellent durability and easy installation in demanding industrial environments.
Built using advanced electromagnetic induction technology, the DN12-4N1 detects metallic objects entering its sensing field by monitoring changes in the generated electromagnetic field. Since the sensor operates without physical contact, it offers excellent reliability, high switching speed, and long service life while eliminating wear associated with mechanical switches. The PNP Normally Open output makes it compatible with PLCs, industrial controllers, relay modules, Arduino, ESP32, STM32, Raspberry Pi, and other embedded control systems using suitable interface circuits.
The M12 Inductive Proximity Sensor features a nickel-plated brass threaded housing with dual mounting nuts for secure installation and easy position adjustment. With a standard M12 cylindrical body and 4mm sensing distance, it is ideal for object detection, position sensing, limit detection, machine automation, counting systems, and safety monitoring. The sensor provides reliable operation under industrial conditions and offers excellent resistance to vibration, dust, and moisture, making it suitable for continuous-duty automation applications.
Designed for engineers, automation technicians, machine builders, manufacturers, researchers, educators, and hobbyists, the M12 Inductive Proximity Sensor DN12-4N1 is widely used in CNC machines, conveyor systems, packaging equipment, textile machinery, robotics, factory automation, material handling systems, and industrial process control. Its compact design, high reliability, and maintenance-free operation make it an essential sensor for modern industrial automation and embedded electronics projects.
