High sensing distances are needed in some environments.  Xecro's Capacitive Sensors offer best-in-class sensing distances. The manufactures shielded capacitive sensors such as e.g. M8 with 2 mm sensing distance, M12 with 6 mm sensing distance and M18 with 15 mm sensing distance. Unshielded Capacitive Performance Series in M30 housings, achieve up to a 35mm sensing distance.

In order to integrate the sensors into different environments, the diameters M12, M18 and M30 are provided with a build-in multi-turn potentiometer to adjust their sensitivity and adapt them to different application requirements. The potentiometer is also an optional extra for Ø6.5 and M8 sensors.

XECRO’s Capacitive - High Temperature Series sensors has been designed for use in permanent environmental temperatures ranging between -25…+150 °C (-13 … 302 °F). The electronics of the Capacitive – High Temperature Series sensors fit into the identical housing as other capacitive sensors from XECRO. These sensors are available in sizes ranging from M8 to M30 and are constructed with silicone or Teflon® (PTFE) cables. Silicone cable has an impressive flexibility which makes it a perfect choice for installations where the sensor permanently moves causing flex in the cable. Conversely, Teflon® has an excellent robustness and should be considered for installations where the sensor body is located on a stationary mount.

The extra thin CS3050 from XECRO is a great choice for installations on non-metal tanks and containers. The built-in potentiometer allows to adjust sensitivity until the device senses material through container walls.

Its flat design, only 7mm in height, eliminates the need for extra fixtures as by cylindrical sensors.

This sensor offers best flexibility due to its rotatable sensing head which can be mounted in five directions. XECRO's sensors in this housing provide NO + NC outputs in the 10… 30 VDC version and in 2-wire for 20…250 VAC.  The sensor electronics and the mounting sockets are two separate parts. This special construction simplifies the replacement procedure of a mechanically damaged sensing head. 

The 40x40 sensors are available in industrial standard sensing distances and in XECROs High Performance sensing distances.

These sensors detect liquids or other high conductive material in tubes. This makes them an ideal choice for level sensing applications based on the principle of communicating pipes.  Since the capacitive sensing principle does not support high switching frequencies, these capacitive ring sensors are only suitable for objects which remain static inside the inner ring.  The circular design of the sensing electrode requires highly conductive material to function. Therefore wooden plugs or lime balls are no suitable targets.
