The sensor is aimed at applications such as positioning workpieces to within fractions of a millimetre, or measuring surface roughness.
The sensor is said to be easy to set up using either built-in teach buttons, or IO-Link. It compensates automatically for changes in air supply pressure over its operating range of 1-3 bar to ensure measurement consistency. The self-cleaning nozzle prevents the build-up of contaminants that might otherwise affect the sensor’s long-term stability and accuracy.
A built-in display shows all key operating parameters, including the gap size (in µm), air pressure and flow rate. The same information is available via IO-Link for easy interfacing with control systems. The sensor also has a conventional analogue output and a digital output that can be programmed to switch on or off at user-defined sensing distances.
Although designed to deliver optimum accuracy at pressures of up to 3 bar, the sensor can withstand pressures up to 6 bar. This means that purge air – used, for example, to clean dust and swarf from a workpiece before a measurement is carried out – can be delivered via the sensor, eliminating the need for a separate delivery system.
The distance-measuring sensor can be used to position workpieces precisely or measure surface roughness
