  RS422 (TTL) incremental encoder

  The optoelectronic incremental TTL encoders are tailored for the use as direct spindle encoders in conjunction with the SINUMERIK 808D CNCs.

  Дизайн

  The direct incremental spindle encoder features a Synchro flange and can be attached to the machine with 3 clamp straps and a spring disk coupling.

  The encoder supply voltage of 5 V DC is provided by the SINUMERIK 808D CNC.

  The direct incremental spindle encoder delivers 1024 pulses per revolution which are multiplied by the factor of 4 internally to reach the precision level suitable for standard lathes and milling machines.

  Incremental encoders operate on the principle of optoelectronic scanning of dividing disks with the transmitted light principle. With an appropriate arrangement of the line pattern on the dividing disk connected to the shaft and the fixed aperture, the optoelectronic elements provide two trace signals A and B at 90° to one another, as well as a reference signal R. The encoder electronics amplify these signals and convert them into different output levels.
