Authorized Distributors

A Mitsubishi Authorized Distributor for MELSERVO-MR-J2 is not the only source for Mitsubishi products. Many of the Mitsubishi products have been discontinued and therefore are no longer available from a Mitsubishi Authorized Supplier of Mitsubishi Automation. TRW Electric and Supply has many new and refurbished Mitsubishi MELSERVO-MR-J2 parts available for purchase.
