FANUC SR-20iA Environmental

The SR-20iA Environmental is a 4-axis SCARA robot with a 20 kg wrist payload and 1100 mm reach, built for secondary food handling and harsh environments. It uses an IP65 body and wrist, corrosion-resistant bolts and bellows covers, with cables and pipes routed internally. It runs on the R-30iB Compact Plus controller and is programmed through the web-based iRProgrammer interface or an optional teach pendant.

Study notes

  • Repeatability is stated per axis: ±0.020 mm (J1, J2), ±0.01 mm (J3), ±0.005° (J4).
  • J3 is a linear vertical axis with 300 mm travel; a 450 mm option is available.
  • J3 maximum speed is 2800 mm/s (linear), so it cannot be expressed as a joint rotation speed.
  • Maximum push force is 250 N.
  • J4 allowable moment/inertia is -/0.45 (N·m / kg·m2).
  • The smaller SR-12iA Environmental option in the same series has 12 kg payload and 900 mm reach.
  • Programming is via the iRProgrammer web interface on a tablet or desktop, or an optional teach pendant.
  • Controller functions listed include iRVision, iRPickTool and conveyor tracking.
  • Controller series is R-30iB Plus; the compatible controller is the R-30iB Compact Plus.

Safety

  • IP65 rating on body and wrist protects against dust and water in washdown and harsh environments.
  • Corrosion-resistant bolts and bellows covers are fitted for secondary food applications.
