EATON D26MR40A 4-Pin Ice Cube Relay

Product Dimensions：

The EATON D26MR40A is a heavy-duty, industrial-grade Machine Tool Relay from the established D26 Series. Known for its exceptional reliability and modularity, it is a staple in automotive and heavy manufacturing control systems where “downtime” is not an option.

Product Detailed Description

The D26MR40A is a 4-pole AC control relay. The “M” in the model name signifies its multipole nature, and the “R” indicates it is part of the Freedom Series logic. It is specifically designed for applications requiring high contact reliability and the ability to expand the number of contacts easily.

Technical Parameters

Product Advantages

• Exceptional Durability: Built to withstand millions of mechanical operations, making it ideal for high-cycle machine tool applications.

• Modular Flexibility: The D26 series allows for the addition of “deck” blocks. You can easily add more poles (up to 12 poles total) or pneumatic timers to the base unit without replacing the relay.

• Convertible Contacts: While this specific model comes as 4 NO, the contacts on D26 relays are often designed to be easily converted from NO to NC (Normally Closed) by simply flipping the contact cartridge.

• Reliable Switching: Designed with a high-force magnet system that ensures positive contact seating even in high-vibration industrial environments.

Important Considerations (Precautions)

• Coil Voltage Sensitivity: Ensure the control circuit provides a stable 110/120V AC. Significant under-voltage can cause “chattering,” which leads to contact welding or coil burnout.

• Contact Conversion: If you choose to convert a contact from NO to NC, ensure the power is completely disconnected, as the internal springs and cartridges are small and require precise seating.

• Wiring Clearance: Because these are often used in dense control panels, ensure adequate spacing for heat dissipation if multiple relays are mounted side-by-side and energized simultaneously.

Product Applications

The EATON D26MR40A is widely used in:

• Automotive Assembly Lines: For interlocking logic between different sections of a conveyor or robotic arm.

• Machine Tool Control: Managing the sequencing of drills, lathes, and milling machines.

• Conveyor Systems: Acting as the logic interface for start/stop sequences and emergency branch controls.

• Heavy Industrial Logic: Replacing or supplementing PLC outputs where high-amperage switching or physical isolation is required.
