    • Internal routing of cables and air hoses prevents interfaces form cables around devices

    Made for applications in dedicated environments

    • RH-6/12/20FRH robots have protection class IP54 as standard and can be increased to IP65 by adding a bellow
    • Mulit-resistant robots with FDA compliant chemical-resistant coating and advanced sealing making them ideal for food and pharmaceutical production 
    • ESD certified and modified robots according IEC 61340-5-1:2024 / ANSI/ESD S20.20:2021 for electronic industry

    High productivity

    • Ultra-fast cycle times of up to 0.29 seconds and optimized motion reduces takt time, increasing throughput
    • High repeatability (+-0.012mm to +-0.015mm) ensures consistent precision in pick-and-place, assembly and handling provess for highest quality 
    • Tracking function is integrated as a standard feature to reduce cycle times and system costs 

    Ensuring the safety of the operator and equipment

    • Operators and robots share an operation area as the robot does not approach the area (Safety-Limited Position) or can continues its operation at the safety speed to secure operator's safety (Safety-Limted Speed) 
    • MELFA SafePlus safety technology support Safety functions: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operation Stop), SLS (Safely-Limited Speed), SLP (Safely-Limited Position)
    • Logic for each safe I/O can be edited and in combination with the position monitoring function, a safe system can be constructed without using a Safety PLC
    • Activation the safety functions via CC-Link IE TSN Safety communication function to simplify system configuration by reducing wiring for safety devices

    Intelligent tasks are simplifying setup and maintenance by MELFA Smart Plus

    • Intelligent functions are added for enhanced force sensor control to autonomous adjust the force for optimum operation pattern
    • Autonomous startup adjustment functions are included like Robot mechanism temperature compensation function, calibration assistance function, coordinated control for additional axes
    • Predictive maintenance function which early detects abnormalities in drive system components like gear, ball screw, belt, bearing, grease… before serious failure happen and predict sudden breakdowns
    • Connectivity with Mitsubishi PLCs and FA equipment enables seamless integration

    CR800 Robot Controller

    D Type controller

    • Standalone solution
    • Various interfaces as standard, allowing customers to build a system optimized for their applications
    • Communication interfaces for Profibus, Profinet, EtherCAT, Ethernet/IP, Devicenet, CC-Link, CC-Link IE
    • Real time control of complex movements generated by external PC retrieving position commands in real time at cycle intervals
    • Up to 8 additional axes can be controlled without using an additional dedicated control device

      R Type Controller

      • Multi CPU System up to 3CPUs (Robot, PLC, Motion, Process, CNC, C)
      • Seamless integration in iQ-R platform
      • Collision avoidance in narrow workspace
      • Coordinated control between multiple robots
      • Improves its interaction with FA equipment

      RH-FRH product portfolio

      RH-CRH series benefits

      Excellent cost performance by compact and lightweight design

      • The CRH Series offers multiple payload capacities from 3kg to 20kg and arm reach up to 1000mm to suit in various applications
      • High repeatability (as precise as ±0.01 mm) ensures consistent and accurate task execution
      • The versatility allows these robots to handle both lightweight and medium-weight components effectively
      • These robots are suitable for diverse applications in electronics or medical/pharmaceutical markets, including assembly, pick-and-place, inspection, packaging, and material handling such you as electronics assembly or medical device manufacturing

      Maximize the workspace with our compact robot design

      • Overall height of the RH-CRH series has been reduced by making the arm cover compact
      • Designed to fit in tight spaces, these robots are perfect for small production lines or work cells
      • The compact form factor minimizes the footprint, enabling efficient use of factory floor space
      • High repeatability (as precise as ±0.01 mm) ensures consistent and accurate task execution

      Reducing the total cost of ownership

      • Competitive pricing makes the CRH Series an excellent choice for businesses seeking advanced robotics without a hefty investment
      • Low operating costs due to energy efficiency and reliability further enhance cost savings
      • Thanks to Mitsubishi Electric’s latest motor technology, no backup batteries are required for its internal encoders which means no material cost and labor costs are associated with periodic battery replacements

      Ensuring the safety of the operator and equipment

      • Operators and robots share an operation area as the robot does not approach the area (Safety-Limted Position) or can continues its operation at the safety speed to secure operator’s safety (Safety-Limited Speed)
      • MELFA SafePlus safety technology support Safety functions: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operation Stop), SLS (Safely-Limited Speed), SLP (Safely-Limited Position)
