Original P+F distacne sesnor The OMR50M-R1000-SSI-V1V1B distance sensor for positioning tasks accurate to the millimeter, PRT. The detectiing distacne can be up to 50 m. The interface is SSI/RS-422 with M12 plug. The R1000 series is based on pulse ranging technology (PRT) by Pepperl+Fuchs P+F. For small and large ranges, these distance sensors are very precise which makes them ideally suitable for positioning tasks. The red laser diode is clearly visible, allowing direct alignment of the device for reliable operation.
