The IFM KB5004 is a cylindrical PNP capacitive sensor designed for industrial level and presence detection. It provides an adjustable sensing range of 3 to 20 mm. The sensor operates from 10 to 36 V DC and provides a normally open output. Its PBT housing and increased noise immunity support reliable operation in demanding environments. The sensor is particularly suitable for liquid, adhesive and bulk-material detection applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KB5004 provides a 3 to 20 mm adjustable sensing range. Its factory setting is 20 mm with a real sensing range of 20 ±10%. The operating distance is 0 to 16.2 mm. Hysteresis is specified between 1 and 15% of Sr. The correction factors for glass, water, ceramics and PVC allow the sensing characteristics to be considered for different materials.
The sensor uses a DC PNP normally open output. It operates from 10 to 36 V DC with approximately 13 mA current consumption at 24 V. The output can continuously switch up to 250 mA. Switching frequency is 40 Hz. Short-circuit and overload protection are integrated.
The KB5004 has a cylindrical Ø34 × 81 mm PBT housing. It is designed for non-flush mounting and has IP65 protection. Increased immunity to conducted RF interference supports stable operation near electrical equipment. A yellow LED provides switching-status indication. The model uses a 2 m PVC cable with 3 × 0.5 mm² conductors.

The KB5004 is well suited to adhesive and material-level monitoring applications. Its adjustable sensing range allows the detection point to be tuned to the process. The capacitive principle allows non-contact detection without mechanical wear. Increased noise immunity helps maintain stable operation around machine electronics. The PBT construction provides a robust solution for industrial machinery.
The integrated adjustment allows operators to configure the sensing range during machine commissioning. The yellow LED gives immediate visual feedback. The 250 mA output rating supports common industrial control loads. Short-circuit and overload protection reduce electrical risk. IP65 protection supports installation in general industrial environments.
