• Capacitive proximity sensing offers increased usability, improved industrial design, and increased functionality with many different consumer applications

A capacitive proximity sensor is a non-contact device that is able to detect the presence or absence of virtually any object regardless of material. The sensors do this by using the electrical property of capacitance and the change of capacitance based on a change in the electrical field around the active face of the sensor.

These sensors are especially useful for level sensing in production or laboratory environments where certain attributes need to be monitored for effective working and for the guarantee of quality, like measuring pressure, flow, thickness, liquid level and so much more.

This sensor uses 2m PVC cable connector
