Inductive sensors
• Reliable detection of metallic objects
• Product variants for standard or three-fold switching distances
• Robust cylindrical or cuboid metal housing options


Typical Inductive sensors

Because of their functional principle, inductive sensors are only suitable for detecting metal objects. But they do this extremely reliably and are also very robust and resistant (e.g. regarding environmental factors), which makes them interesting for numerous industrial applications.




Capacitive sensors

The electro sensitive bloodhounds detect metallic and non-metallic objects of all types.>

• Switching distances from 0.1 to 30 mm
• Robust cylindrical stainless steel housings (6.5 to 30 mm)
• Easy mounting thanks to conventional cylinder construction
Typical Capacitive sensors

Capacitive sensors are suitable for the detection of metallic and non-metallic objects of all types. Even highly transparent glasses or liquids are easy to detect with a capacitive sensor. Only the dielectric conductivity of the target material is relevant: the greater the dielectric constant of a material, the higher the possible switching distances or the more reliable the detection.

Reliable detection of objects with critical surfaces and highly transparent objects.

• Reliable detection of objects with critical surfaces and highly transparent objects
• Available in cubic (32 x 20 x 12 mm3) or cylindrical (M12/M18/M30) housing options
• Simple adjustment via teach-in, control input or display
Typical Ultrasonic sensors
  Ultrasonic sensors may be a useful alternative where optical sensors come up against their physical limits. This applies, for example, for objects with uneven surfaces or under difficult ambient conditions, or with highly transparent media as well as moving, highly reflective liquid surfaces.

Typical uses of ultrasonic sensors are therefore checking the presence of highly transparent foils and measuring the filling levels in liquid containers. A major advantage of ultrasonic sensors is the absolutely reliable background suppression resulting from their sound time-of-flight measurement principle.
