Custom hotshoe solutions


Eaton utilizes modular designs and standardized production processes to facilitate quick-turn development of custom plug/cable assemblies (depicted above) and receptacles (depicted to left). Additional design options and features include:

  • Accordion or pogo pin contacts. 
  • Single or redundant contacts with pointed, cupped, or radiused-tip geometries.
  • Tail configurations include through hole, SMT, vertical mating, and right-angle mating.
  • Accordion contact advantages include reduced impedances and elimination of the possibility of contaminant build up between contact parts

MIL-DTL-55116 form factor 19 & 27 contact connectors


These high-contact density, 19 and 27 pin solutions support mixed audio, signal, and data applications that require more contacts than provided by MIL-DTL-55116 QPL connectors.

  • Gold-over-nickel contacts are rated for 0.23 amps and 3000 mate and demate cycles.
  • 500 Vrms dielectric withstand voltage.
  • Passivated, stainless-steel shells.
  • Solutions include EMI/RFI filtered receptacles.
  • Custom capabilities include cable assemblies and wiring harnesses.

MIL-DTL-55181 power splitters


Power splitters are available to distribute power to multiple cables, plugs, or receptacles.

The stacking connector depicted to the left distributes power without the use of Y cables by incorporating plug contacts on the front mating surface and receptacle contacts on the rear.

The stacking connector plug contacts are mated to the battery. Internal contacts provide electrical continuity between the plug contacts, attached cable, and receptacle contacts that are mated to the QPL connector stacked on top of it. When used without a "piggybacked" connector mated to the receptacle contacts, the stacking connector functions identical to a MIL-DTL-55181 plug.

Filtered receptacles


EMI-filtered receptacles are available as standard products and custom solutions in five and six pin configurations with all pins, or only selected pins, filtered.

  • Standard panel-mount receptacles incorporate low pass, pi network, ferrite-ceramic capacitors. Each pin is surrounded by a filter that is connected to an internal ground plane. Standard products are designed for a 100 VDC working voltage with dielectric-withstand voltages up to 500 VDC.
  • Custom solutions can be developed for panel mount or cable mounting to meet a wide range of application-specific voltage, frequency, and impedance requirements. End-to-end filtered solution capabilities include custom connector/cable assemblies.

Custom Cable Assemblies and Wiring Harnesses

Military and aerospace cable assembly and wiring harness capabilities include overmolded, coaxial, flat ribbon, and fiber optic for power, data, and hybrid applications.

Solution-development expertise includes operation in extreme environments including extended temperature ranges, shock and vibration, radiation, EMI/RFI, corrosive contaminants, vacuum, and pressures to 20,000 PSI.

In addition to turnkey design and manufacturing for new projects, build-to-print services for production-ready designs are also available.
