Key Features That Enhance Automation System Performance

The MJC Series Auto Hand Changer allows robots and automated machinery to change hands or tools automatically. It is well-suited for production lines that frequently change workpieces, parts, or robot end-effectors.

• Automatic Hand/Tool Changing: Reduces end-effector changeover steps and increases flexibility for automation systems
• Supports Payload of 3-150 kg: Available in 6 models — MJC3, MJC10, MJC20, MJC60, MJC100, and MJC150 — covering everything from light-duty to heavy-duty applications
• Compact and Lightweight Structure: Enables more agile robot movement and supports more efficient automation system operation
• Supports Both Pneumatic and Electrical Systems: Can transmit air and electrical signals to the Tool Side, allowing end-effectors to operate continuously

Anti-drop Mechanism for Emergency Situations

The safety of workpieces, tools, and machinery is critical. The MJC Series comes equipped with an Anti-drop mechanism that maintains the locked state between the Master Side and Tool Side.

In the event that air supply is cut off or a power outage occurs while the unit is in the coupled state, the internal mechanism prevents the Tool Side from disengaging from the Master Side, reducing the risk of damage to tools, workpieces, and the production system.

Specifications and Payload Capacity

To accommodate a wide range of applications, the MJC Series offers multiple models based on payload rating, as follows:

Pneumatic and Electrical Connections

The MJC Series supports transmission of both air and electrical signals to the Tool Side, enabling hands or robot end-effectors to operate efficiently.

• Pneumatic Ports by Model: Supports 4-13 pneumatic ports, with the number and size of ports varying by the selected model
• Various Electrical Interfaces: Options include Solder Terminals, Solder Terminals with Cables, Mini-connectors, D-sub Connector, Non-contact Terminals, and Round Connectors, with supported models varying by connector type

Structural Materials and Mounting Options

• Durable Materials for Industrial Use: The Master Side is made of Aluminum Alloy with Electroless Nickel Plating for durability
• Supports High-Load Applications: For the MJC60, MJC100, and MJC150 models, the Tool Plate is made of heat-treated Stainless Steel to withstand applications requiring higher strength
• Convenient Robot Installation: A Robot Adapter is available for mounting the Auto Hand Changer MJC to robots, referencing ISO (JIS) standards to facilitate installation with various robot systems

Frequently Asked Questions (FAQ)

Q: What is the payload capacity range of the MJC Series?
A: The MJC Series offers 6 models supporting payloads of 3 kg, 10 kg, 20 kg, 60 kg, 100 kg, and 150 kg.

Q: Can the MJC3 model be fitted with a D-sub Connector?
A: The MJC3 model does not support a D-sub Connector. It can instead use Solder Terminals, Solder Terminals with Cables, or Mini-connectors.

Q: Does the MJC Series have a mechanism to prevent the Tool Side from dropping?
A: Yes, it is equipped with an Anti-drop mechanism that maintains the locked state in the event of air supply cutoff or power outage while the unit is in the coupled state.
