FANUC A61L-0001-0093 CRT dim display: technical specs

#cnc #manufacturing #engineering #fanuc

Technical Details

The A61L-0001-0093 CRT in FANUC systems connects via Honda MR-20M (20-pin) and runs on DC 24V. It's compatible with 0-TC, 0-MC, 18-T controls. The LCD replacement uses the same connector and power — no adapter needed. Price: $199.

Brightness was measured at <100 cd/m² on an aged CRT vs. 350-450 cd/m² on the replacement LCD. Even at maximum brightness, the old CRT can't compete with shop floor lighting.

Cost Comparison: Repair vs Replace

Option Cost Lifespan
CRT repair (rebuilt HV section) $199–398 each 3-12 months
CRT repair (donor tube swap) $299–499 6-18 months
Used CRT on eBay $398–597 Unknown (already aged)
LCD replacement module $199 (one-time) 5-7 years continuous

Over 5 years: CRT repairs cost 995–1990, while a single LCD costs $199. The math is clear.

Installation

  1. Power off CNC machine and verify power is off with multimeter
  2. Remove 4 mounting bolts from the CRT bezel
  3. Disconnect the Honda MR-20M cable
  4. Connect same cable to the replacement LCD module
  5. Mount LCD using original screw holes (same pattern)
  6. Power on — no CNC parameter changes required

Total time: ~15 minutes. The LCD draws DC 24V, matching the original CRT power supply.

Summary

Every FANUC A61L-0001-0093 CRT will eventually fail. Plan the upgrade now instead of scrambling during a production emergency. Details: https://cncdisplay.com/brands/FANUC.html
