LMR Series Rack and Panel Connectors offer alternative to obsolete ITW McMurdo Connectors RED Range

Robust connector system specifically designed for demanding environments. Form, fit and function replacement for ITW McMurdo RED range.

Our LMR Series of rack and panel connectors provide a form, fit and function alternative to the ITW McMurdo Connectors RED Range which was made obsolete in 2024. Most residual stock of this widely used connector family has now been consumed but our sister company, specialist connector distributor Lane Electronics is able to maintain supply to existing and new customers with our direct alternative.

Matching the technical performance and dimensions of the RED Range, our LMR series is a compact and heavy-duty rectangular rack and panel connector system that is designed to provide a drop-in replacement to the RED Range for Line Removable Units (LRUs) and is particularly suited for use in rugged conditions where reliability is essential, and space and accessibility are a premium.

Our LMR range offers four connector sizes, providing 8, 16, 24 and 32 ways with low insertion force and polarised blind-mate moulded insulators.  Each of the male and female halves of the connector system consists of a combined high-performance Diallyl-Phthalate (DAP) moulded insulator and stainless-steel mounting plate (the ITW McMurdo Connectors RED Range offered DAP and a lower temperature grade Nylon) fitted with gold plated low insertion force blade contacts rated for 500+ operations.  

The insulator form has generous polarising and pre-mating features which engage before contacts touch that makes it ideally suited for inaccessible applications and the female half is fitted with floating mounting bushes to further enhance the self-aligning functionality. Contact rating is a high 5A continuous across all contacts simultaneously at 100°C and the complete connector assembly meets a climate category of 55/125/56 (-55°C to +125°C temperature range).

With high-quality materials and excellent current carrying characteristics the LMR range of connectors provide reliable connectivity for line-replaceable industrial electronics units such as industrial measurement and configurable automation and robotics.

• Rugged construction
• 180° polarised
• Floating bushes to assist alignment
