Compact, high-precision edge sensors set new standards

The combination of these new sensors with their established smart 2D OX series of profile sensors provides users with ultra-reliable and flexible edge measurement options to suit different precision levels and available space conditions across a wide range of applications.

Key features and benefits include; Edge detection with up to 1µm precision with repeat accuracy at a distance of up to 100mm, flexible design to suit different functional principles, compact and easy to integrate along with connectivity options including IO-Link, EtherCAT and Modbus
RTU.

The portfolio includes the high-performance OE60 and OE60C providing best-in-class precision of up to 1µm across a measuring range of up to 10mm, the OE40 which delivers measuring precision up to 24mm, detection of transparent edges along with plug-and-play ability thanks to a reflection bracket. 

Completing the edge sensing ‘portfolio’ are the OXS smart profile sensors for measurement of multiple edges and step heights, providing resolution of up to 30µm in X-direction and up to 5µm in Z-direction.

The high-precision OE60 sensors are
claimed to be the only ones in their class that can be deployed as stand-alone devices without the need for a controller unit, because the sensor heads are designed to directly integrate into the control via the standardized Modbus RTU protocol. This eliminates the need for an additional device and therefore reduces overall costs. 

Examples of applications where these sensors will be especially beneficial include battery cell production, where edge measurements must be extremely precise as the individual layer positioning (anode, cathode and
separator foil) in the winding process defines service life, capacity and even battery safety.

Reliable detection of the individual tracks, even at high speeds, is crucial in battery production and the OE60 succeeds thanks to the very short response time combined with outstanding precision of 1µm which is achieved without the need for any filtering. 

Another potential application is web edge control in the packaging industry where edge detection of transparent films with optical sensors is a major challenge. 

The OE40 plays to its
strengths with its reflector bracket reliably and precisely measuring edge positions on thin transparent films where optical sensors would reach their limits. 

Finally, in the wood processing industry, the smart 2D profile sensor can check floor planks to identify any non-compliance of tongue and groove. 

By measuring the edge position the sensor identifies the depth or width of the tongue and groove with the measured results delivered straight to the system so that issues such as tool wear can be detected early by any change in the height profile.
