SCARA Robots

Applications include pick and place, tray loading, component insertion, screwdriving, dispensing, inspection, packaging and general material handling. RH-CR and RH-FR models address these roles with slim arms, generous I/O, vision compatibility and optional ceiling mounting.

RH-FR robots interface with Mitsubishi Electric PLCs and factory automation equipment for coordinated motion, interlocks and data exchange. Vision compatibility supports part location, orientation checking and in-cycle inspection without manual intervention.

he RH-FR series represents the advanced FR series platform featuring three key capabilities: next-generation intelligent functions, safe collaborative work applications, and FA-IT integration functions. This series offers comprehensive safety monitoring, including position and speed monitoring with X, Y and Z component tracking, enabling collaborative operation alongside human workers. The RH-FR series offers environmental ratings from IP40 to IP67 for oil-mist environments and ISO Class 3 for cleanroom applications, making it suitable for demanding manufacturing conditions.

The RH-CRH series prioritises compact design and cost-effectiveness, with lightweight construction up to 69% lighter than previous models and battery-less motors that eliminate periodic replacement requirements. Both series share core SCARA architecture benefits, including high-speed operation and precise positioning, but are optimised for different operational priorities—advanced intelligent features and comprehensive safety for RH-FRH, and compact efficiency for RH-CRH.

Mitsubishi Electric can help match a robot and controller to your process and provide training. To buy SCARA robot solutions or arrange a demonstration, contact your local Mitsubishi Electric Automation Distributor or a Mitsubishi Electric System Integrator.

Yes, Mitsubishi Electric SCARA robots are available in cleanroom specifications that meet ISO Class 3 or ISO Class 5 standards, making them suitable for hygienic applications in semiconductor, medical, pharmaceutical and food manufacturing environments. Preservation of cleanliness levels depends on the downstream flow rate of 0.3 metres per second in the cleanroom and on internal robot suctioning.

Mitsubishi Electric offers standard robots with H1 food-grade grease, as well as specially protected robots with a chemical-resistant coating that withstands cleaning processes for food-handling applications. These environmental specifications enable SCARA robots to operate in demanding hygienic environments whilst maintaining the required contamination control standards. Customers should consult with Mitsubishi Electric authorised distributors or system integrators to specify the appropriate cleanroom class requirements for their application.

Yes, selected Mitsubishi Electric SCARA models support ceiling-mounted or inverted installation, providing space-saving solutions when floor space is limited. The RH-3FHR series offers ceiling-mounted horizontal multi-joint SCARA configuration with cleanroom specifications.

Overhead installation maximises workspace utilisation by freeing up valuable floor space whilst maintaining full operational capability. This mounting flexibility allows SCARA robots to be integrated into compact production cells and multi-level manufacturing systems. Customers should verify specific model compatibility and payload capacity requirements for inverted installations with a Mitsubishi Electric Automation Distributor or a Mitsubishi Electric System Integrator during the specification phase.
