Capacitive proximity sensors
KNS Extended
The KNS Extended series detects granular, powdery, liquid and solid materials as well as metallic and non-metallic parts. Parts can also be detected through container walls or packaging. The sensors are available in sizes from Ø6.5 to M32.
Sensors with added value
Our capacitive proximity sensors Ø6.5 to M12 are ideal for high-precision applications in the electronics and automotive industries and other sectors where materials and components must be detected precisely in production processes.
The M18 to M30 are ideal for applications that demand ruggedness, reliability and long service life—even under harsh conditions.
The M32 is our specialist for detecting granulate fill levels—without an additional protective device.
The R20 are flat capacitive proximity sensors and the ideal solution for applications with limited installation space.
Solutions. Clever. Practical.
Benefit from our expertise and rely on solutions that make your production more efficient and sustainable.
KNS Extended M18 and M30
Rugged design. Flexible use.
Developed for demanding industrial applications: The rugged PEEK front cap, the durable metal housing and the temperature-resistant sensor surface up to 120 °C ensure high reliability and a long service life—even under demanding operating conditions.
With NO and NC in a single sensor as well as flush and non-flush versions the series offers great flexibility in selection and integration while reducing the number of variants required. The extended voltage range of 10 … 40 V DC enables use in a wide range of system environments.
Sensitivity can be easily adjusted to the application using the rear-mounted potentiometer .
PUR cable or M12 connector enable rugged and flexible installation.
Advantages of the KNS Extended M18 and M30:
- Long-lasting: rugged PEEK front cap and metal housing
- Temperature-resistant: sensor surface for temperatures up to 120 °C
- Flexible switching: NO and NC in one sensor
- Flexible mounting: flush and non-flush versions for different installation situations
- Versatile integration: extended voltage range of 10 … 40 V DC
- Easy to adjust: rear-mounted potentiometer
- Practical connectivity: PUR cable or M12 connector
KNS Extended M32
Rugged, reliable and long-lasting
When it comes to transporting, dosing, mixing and drying granulate before the injection molding process, our KNS Extended M32 sensors are the perfect solution. Their major advantage is the sensor surface, which resists abrasive substances and temperatures up to 120°C, allowing installation without a protective screen.
The large switching distance of up to 16 mm makes the rugged KNS M32 flexible to use.
Benefits of the KNS Extended M32:
- Large switching distance for reliable object detection
- Withstands static discharges of up to 40 kV
- Temperature-resistant sensor area up to 120°C
- Robust stainless steel housing AISI304
- The durable, highly rugged PEEK front cap also withstands glass-fiber-reinforced abrasive plastic granulates
- Simple operating concept via potentiometer
- Extended voltage range from 10 to 40 V DC
- Low installation effort and easier maintenance provide significant added value

KNS Extended with potentiometer
Applications
The PS-30 takes on your demanding challenges. It captures object profiles and reliably detects differences as small as 0,5 mm in components, assembly operations, milling or drilling compared with the target condition.
Capacitive sensors for non-contact and wear-free detection
The capacitive sensors in the KNS Extended series with potentiometer are robust sensors that offer more than a standard design. They are especially well suited for primary packaging, for detecting contents through containers or packaging. Further applications are found in the process industry in the detection of liquids, powders and solid materials. Their strength is very precisely detecting non-metallic, solid materials via their high degree of sensitivity.
