The device is fitted with two precision ball bearings guaranteeing exceptionally smooth running and a long service life at speeds of up to 80,000 rpm. Inside the miniature housing is the patented unique Elesta encoder system – the E OI R, an integrated system operating on the basis of a new optical focusing incidental light method. Within the integrated system are multiple reflective parabolic shaped concave mirrors, forming the code segments of the code wheel. The cleverly designed mirrors reflect only an extremely clear and steep concentration of light from the transmitter LED, ensuring exact signal quality and accuracy across the entire speed range. The encoder delivers 128 pulses at any rotation speed, to two outputs that are phase shifted by 90°. The third channel provides one index pulse per revolution. The encoder draws 4mA at 5V. The E OI R007 housing is mounted using grub screws, securely braced against rotation. The chamfered output shaft has a diameter of 2mm and is flattened on two sides.
