Absolute linear encoders, RF25X RF25X [Revision 1.1] 10th October 2010 RIFTEK 4 1. Safety precautions · Use supply voltage and interfaces indicated in the sensor specifications. · In connection/disconnection of cables, the sensor power must be switched off. · To obtain stable results, wait about 20 minutes after sensor activation to achieve uniform sensor warm-up. 2. Electromagnetic compatibility The sensors have been developed for use in industry and meet the requirements of the following standards: · EN 55022:2006 Information Technology Equipment. Radio disturbance characteristics. Limits and methods of measurement. · EN 61000-6-2:2005 Electromagnetic compatibility (EMC). Generic standards. Immunity for industrial environments. · EN 61326-1:2006 Electrical Equipment for Measurement, Control, and Laboratory Use. EMC Requirements. General requirements. 3. General information The sensors are intended for contact measuring and checking of position, displacement, dimensions, surface profile, deformation, sorting and sensing of technological objects. The series includes sensors with the measurement range from 15 to 55 mm and the resolution up to 0,1 um. Custom-ordered configurations are possible with parameters different from those shown below. 4.
