Eaton DILM32-XVB (281227) Mechanical Interlock Connector for DILA/DILM7–32
Product Brief Introduction
Eaton DILM32-XVB (catalog number 281227) is a compact mechanical connecting bridge from the Moeller DILM series, designed to mechanically interlock DILA contactor relays and DILM7–32 contactors at 0 mm spacing. It enables safe, space-saving combination mounting of contactors for reversible motor control, star-delta starting, and sequential switching schemes. Built with robust thermoplastic, it operates reliably across –25 °C to +60 °C and carries UL 508, CSA, and CE certifications for global industrial use. As a simple clip-on accessory, it reduces assembly time and ensures precise mechanical coordination between linked devices.
Product Description
Eaton DILM32-XVB is a high-precision mechanical interlock connector engineered as an essential accessory for Eaton’s Moeller DILM and DILA series contactors and relays
Eaton. Designed for direct, zero-gap mounting between adjacent devices, it provides a rigid mechanical link that synchronizes contactor operation while preventing conflicting states—critical for safety in reversing and multi-step motor control circuits. With dimensions of 15.6 mm × 22 mm and a lightweight 1.22 g construction, it adds minimal bulk while delivering reliable mechanical performance in space-optimized control panels.
Manufactured from high-grade, impact-resistant thermoplastic, the DILM32-XVB ensures excellent dimensional stability and resistance to industrial contaminants, vibration, and temperature extremes. Its clip-on design requires no tools for installation: users simply align the connector with the dedicated slots on DILA relays or DILM7–32 contactors and press to secure, creating a firm, backlash-free mechanical connection. This zero-mm spacing capability allows contactors to be mounted side-by-side without gaps, maximizing cabinet space utilization—a key benefit in modern, compact control panel designs.
The connector’s geometry is precision-molded to match the mechanical interface of DILA and DILM7–32 devices, ensuring consistent alignment and smooth mechanical movement throughout the contactor’s operating lifeEaton. It supports the full mechanical stroke of linked contactors, enabling reliable transfer of motion between devices without binding or wear. This precision is vital for applications like forward/reverse motor control, where strict mechanical interlocking prevents simultaneous activation of opposing contactors and eliminates the risk of short circuits.
Operating reliably across an extended temperature range of –25 °C to +60 °C, the DILM32-XVB performs consistently in both cold storage facilities and high-temperature industrial environments. It is fully compliant with IEC/EN 60947-4-1, UL 508, and CSA-C22.2 No. 14-05 standards, and carries CE marking, ensuring compatibility with global electrical codes and facilitating deployment across North America, Europe, Asia, and other regions. The RoHS-compliant construction aligns with environmental regulations, making it suitable for sustainable manufacturing projects.
As a passive mechanical accessory, the DILM32-XVB has zero power dissipation and requires no maintenance, contributing to long-term system reliability and low total cost of ownership. It is compatible with all standard DILA contactor relays and DILM7–32 contactor models, including AC-3 and AC-1 rated versions, making it a versatile addition to new installations and retrofitting projects alikeEaton. Whether used in machine tools, material handling systems, or industrial automation lines, the DILM32-XVB ensures safe, coordinated contactor operation while simplifying panel assembly and reducing wiring complexity.
