Product Introduction
The Shanghai Wujiu C38-2015PH proximity switch is an inductive non-contact position sensor designed for reliable metal object detection in industrial automation systems. Operating without physical contact with moving parts, it provides precise switching signals through electromagnetic field interaction, eliminating mechanical wear and ensuring long-term stability. The device is suitable for position control, counting, and safety monitoring applications across manufacturing, material handling, and processing equipment.13
Key Features
This sensor features a stainless steel housing with resin encapsulation, offering vibration resistance and protection against oil/water ingress (IP67). With 15mm sensing range and 10-30VDC operating voltage, it provides PNP/NPN output options compatible with PLC inputs. The built-in reverse polarity protection and overload prevention circuits enhance operational safety, while the LED status indicator simplifies troubleshooting. Its optimized oscillation frequency ensures stable performance even in environments with electrical noise.47
Operational Principle
The C38-2015PH utilizes electromagnetic induction - when a metal target enters its detection zone, eddy currents generated on the target surface alter the LC oscillator s energy state. This change is converted into a clean digital signal through advanced processing circuitry. The sensor demonstrates highest sensitivity to ferrous metals, with adjustable detection thresholds for non-ferrous materials through installation distance optimization. The contactless design enables over 100,000 operation cycles without degradation.912
Typical Applications
Ideal for integration into automated production lines, this sensor performs object presence detection, conveyor speed monitoring, and equipment positioning in industries including automotive, packaging, and metalworking. Its M30×1.5 threaded barrel allows flexible flush or non-flush mounting near moving machinery components. When connected to control systems, it enables precise coordination of sequential operations while withstanding industrial environmental challenges.1016
