Tension Controller

    Controls the tension during unwinding/rewinding of long materials

    Mitsubishi Electric tension controllers are dedicated automatic control units designed to regulate the tension of long materials during winding, unwinding, and intermediate shaft processing on industrial production lines. Working in conjunction with Mitsubishi powder clutches, powder brakes, and tension detectors, the tension controller closes the feedback loop continuously measuring the actual tension via a tension detector and adjusting the output to the powder clutch or brake to maintain the target tension set by the operator. DahebTech is an officially authorised Mitsubishi Electric dealer in the UAE, supplying the complete LE7 and LD series tension controller range to industrial clients across all sectors. Every unit we supply is genuine, certified, and backed by full manufacturer warranty. Whether you are specifying a new tension control system, upgrading from a legacy LE-40MTA or LE-30CTN unit, or sourcing a replacement controller for an existing installation, our technical team provides selection guidance and reliable supply across the UAE.

    Mitsubishi Tension Controllers UAE

    A Mitsubishi tension controller is an automatic control unit that regulates material web tension during winding or unwinding on industrial processing lines. It receives a tension measurement from a tension detector, compares it to the operator-set target tension, and outputs a DC excitation signal to a powder clutch or brake to correct the tension. This closed-loop control maintains consistent web tension throughout the full reel cycle regardless of reel diameter changes.
    The Mitsubishi LE7-40GU-L is the current generation replacement for the LE-40MTA, LE-40MTB, and LE-30CTN/A series tension controllers. It offers improved performance including faster response time, Ethernet and RS-485 communication, and a more compact design. DahebTech in the UAE stocks the LE7-40GU-L contact us at +971 55 531 6164 or info@dahebtech.com to confirm compatibility with your existing installation.
    The LE7-40GU-L is the flagship model with Ethernet and RS-485 communication and high-speed processing. The LD series (LD-30FTA standard, LD-05TL compact) covers applications where the full communication capability of the LE7-40GU-L is not required. Both series work with Mitsubishi ZKB and ZKG powder clutches and brakes and LX series tension detectors.
    Yes. The LE7-40GU-L communicates with Mitsubishi MELSEC PLCs via Ethernet and RS-485. The LM-10WA-CCL variant connects directly to CC-Link networks for seamless integration with iQ-R and Q series PLC-based machine control systems. DahebTech supplies both tension controllers and MELSEC PLCs — contact us for complete system integration support.
    DahebTech is an officially authorised Mitsubishi Electric dealer in the UAE, supplying the complete LE7 and LD series range including LE7-40GU-L, LD-30FTA, LD-05TL, LM-10WA-CCL, and LX series tension detectors. We also supply ZKB/ZKG powder clutches and brakes for complete tension control system supply. Contact us at +971 55 531 6164 or info@dahebtech.com.
    Mitsubishi LE7 and LD series controllers output a standard DC excitation signal compatible with most powder clutch and brake manufacturers. However, using Mitsubishi ZKB and ZKG series powder clutches and brakes is recommended for fully warranted, factory-tested performance and simplified after-sales support.
