Mitsubishi MELFA RH-12CRH SCARA Robot

The Mitsubishi MELFA RH-12CRH SCARA (Selective Compliance Assembly Robot Arm) is a high-speed, high-precision four-axis robot designed for flat-plane assembly, dispensing, screw driving, and palletising applications where payload and reach requirements exceed what compact SCARA robots can handle. With a 12 kg rated payload, a 1200 mm maximum reach, and a ±0.01 mm repeatability specification, the RH-12CRH1212 is the production-proven choice for Saudi Arabia's electronics, solar panel, and white goods assembly sectors — markets where Vision 2030's National Investment Strategy is directing billions of SAR in localisation incentive packages. The SCARA configuration inherently provides rigidity in the vertical axis, making it ideal for press-fit, screw driving, and dispensing operations where vertical force control is required without a six-axis wrist; this results in a lower cost-per-axis compared with articulated robots for planar tasks.

The RH-12CRH's maximum TCP speed of 8,700 mm/s on the horizontal plane, combined with a 167 ms standard Adept cycle, enables throughput of more than 300 pick-and-place operations per minute in continuous production — directly supporting Saudi Arabia's labour substitution goals under Vision 2030, which targets a 45% increase in manufacturing sector productivity by 2030. The arm's slim 200 V or 400 V power supply compatibility allows installation in both legacy 200 V Japanese equipment factories retrofitting to Mitsubishi robotics and new 400 V European-standard Saudi greenfield plants. The CR800-R controller (SCARA-specific variant) connects natively to CC-Link IE Field and supports RT Toolbox3 offline programming, enabling engineering teams at system integrators in Jeddah, Riyadh, and Dammam to complete offline cell simulation before robot delivery.

Saudi Arabia's solar energy sector — anchored by NEOM's ENOWA power grid, the Red Sea Project, and ARAMCO's photovoltaic initiatives — requires high-volume assembly of solar panel junction boxes and string inverter PCBs. The RH-12CRH is qualified by Mitsubishi Electric for ESD-sensitive handling with grounded gripper interfaces, making it directly applicable to photovoltaic module assembly lines being established at Jubail and Ras Al-Khair industrial zones. Additionally, the Kingdom's HVAC equipment manufacturing sector — growing rapidly to serve Vision 2030 mega-project site services — deploys MELFA RH robots for brazing ring loading and coil alignment in split AC production lines at factories in Riyadh Second Industrial City and Khamis Mushait.

Razz Middle East provides complete MELFA RH-12CRH system packages including gripper specification, safety fencing design, robot programming, and 24/7 remote monitoring via the e-F@ctory Alliance IIoT platform. We hold demo equipment for Saudi customer trials and can arrange visits to reference installations across the GCC. Extended warranty to 36 months and preventive maintenance contracts ensure maximum uptime across the robot's design life of 60,000 operating hours.
