Switching Diffuse Mode Sensor

The new Pepperl+Fuchs diffuse mode sensor with MLV41-8-H-IO measuring core uses multi-pixel technology (MPT) and detects objects based on their distance from the sensor. Multi-pixel technology combines the triangulation principle with the measuring functionality of distance sensors in a flexible solution that detects objects and suppresses interference. The sensor detects objects based on their distance from the sensor using a row of photodiodes (multi-pixel array) as a receiver. The reflected light beam strikes different positions on the multi-pixel array depending on the distance. Using a microprocessor and appropriate software algorithms, the MPT sensors then calculate the object distance based on data regarding where on the receiver array most of the reflected light strikes. This has the advantage that the sensors with MPT are extremely insensitive to differences with regard to reflection or the color of the object. The intelligent evaluation of the measured data permits various switching functionalities with outstanding technical features to be implemented in a single device. The device can be very easily adapted to the relevant application using the IO-Link interface provided as standard. Available sensor functions include background suppression, background evaluation, foreground and background suppression, and a hysteresis mode. Existing configurations can quickly be transferred at the push of a button when a device is replaced or a new job is started.
