Electronic display MA55

Incremental, length and angle measurement

Freely programmable 5-digit measurement display for the evaluation of incremental measurement information obtained from length and angle sensors.

Profile MA55:

  • LED display (1 line of 5 digits)
  • Input for incremental encoder recognition of the counting direction for length and angle measurement
  • Free programming via front keyboard
  • Non-volatile parameter storage (EEPROM)
  • With reference connection
  • Integrated quadruple evaluation of counting pulses
  • Compact design
