McMurdo Red Range Rack & Panel Connectors

The McMurdo Red Range is a heavy duty rectangular rack and panel, line to line or panel connector with low insertion and withdrawal forces. It is particularly suited for use in rugged conditions. Available to order at factory MOQs and lead times.



The standard, barrier polarised Red Range style is available in either Nylon Phenolic for normal environments, or Diallyl-Phthalate (DAP) for more severe environments; whilst the barrier polarised types available in both as 16 way, but DAP only in 24 and 32 way versions.

The moulded Nylon insulator of these Red Range panel connectors will withstand -50°C to 100°C. Rugged and heavy duty they are superb in industrial/commercial equipment like bank ATM, vending and office machines, gaming equipment, mobile radios, TV cameras and industrial control applications where larger gauge wires of up to 16AWG are required.

Two wide, positive pressure contact points produce a self-cleaning and wiping action to keep surfaces clean for low-resistance and continuity. Both solder eye and PCB mount contact tails are possible. The strong, low insertion force, self-wiping contacts of these connectors are designed such that the plug and socket will self-align. This makes Red Range connectors ideal as power edge card connectors for inaccessible applications such as the rear of sliding trays and panels, on cable ends or even as battery connections in hand held measuring instruments. They have been specifically designed to prevent misalignment and damaged contacts in such “blind” mating. These cost efficient rack & panel connectors are capable of handling 5 Amps per contact (all contacts simultaneously) at 100°C ambient and 750V rms.

In2Connect stock hoods suitable for cable mounting the whole family of ITW McMurdo Red Range Connectors ~ from 8 way (RC108), 16 way (RC116), 24 way (RC124) to 32 way (RC132)
