The IFM KG5047 is a programmable PNP/NPN capacitive sensor designed for flexible industrial detection. It provides an 8 mm sensing range with selectable normally open and normally closed output operation. The sensor operates from 10 to 55 V DC. Its M18 × 1 threaded housing provides a compact non-flush mounting format. The programmable electrical design makes the sensor suitable for control systems requiring either PNP or NPN behavior.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KG5047 supports automatic PNP/NPN load detection. Output behavior can be selected between normally open and normally closed. This reduces the need to stock separate sensor versions for different control architectures. The sensor operates across a wide 10 to 55 V DC supply range. This flexibility is useful for machine builders and maintenance teams.
The sensor provides an 8 mm sensing range. The range is adjustable with an 8 mm factory setting. The real sensing range is 8 ±10%. Operating distance is 0 to 6.5 mm. Hysteresis is 1 to 15% of Sr.
The sensor provides a maximum voltage drop of 4.6 V. Minimum load current is 4 mA and maximum leakage current is 1 mA. Continuous output current is 250 mA, with 400 mA permitted up to 50°C. Switching frequency is 50 Hz. Short-circuit and overload protection are included.

Automatic PNP/NPN detection provides flexibility across different PLC architectures. This can reduce the need for separate sensor variants. NO/NC selection further expands the possible control configurations. The 10 to 55 V DC range supports a broad supply window. These features make the KG5047 useful for replacement and retrofit applications.
The M18 × 1 threaded housing provides secure machine mounting. The adjustable sensing range supports application-specific commissioning. Electrical protection helps protect the sensor from common faults. The 8 mm range supports close-proximity detection. This combination provides a flexible industrial sensor platform.
