Inductive proximity sensors

Inductive proximity sensors are used for contactless obtaining information about the movements of the working bodies of machines, robots, etc. These sensors converting this information into an electrical signal. They are widely used in almost all branches of industry and are the most important elements of automation systems.

They operating principle is based on a coil and oscillator which creates an electromagnetic field in the close surroundings of the sensing surface. The presence of a metallic object (actuator) in the operating area causes changes of the oscillation amplitude. The rise or fall of such oscillation is identified by a threshold circuit which changes the output of the sensor. The operating distance of the sensor depends on the actuator's shape and size and is strictly linked to the nature of the material.

We produce two groups of inductive sensors with outputs:
– DC Voltage;
– AC Voltage;
