Guidelines for power connector selection
With more than 40 different designs of coaxial power connectors in existence which are used to power electronic products, the lack of a clear starting point for selecting one has helped lead to the wide inconsistencies among various power plugs and devices. Here are some guidelines that can be drawn from the few power connector designs that have clear voltage specifications associated with them.
- 1.5 V devices
- EIAJ-01
- 3.0 V devices
- EIAJ -01
- 4.5 V devices
- 6.0 V devices
- 7.5 V devices
- EIAJ -03
- 9.0 V devices
- EIAJ -03
- 10.5 V devices
- EIAJ -03
- 12.0 V devices, including automotive electrical systems
- 13.5 V devices
- 15.0 V devices
- EIAJ -05
- ARINC 628/EmPower for automotive or airplane use
- 16.5 V devices
- EIAJ -05
- 18.0 V devices
- EIAJ -05
Note that the special ARINC 628/EmPower connector (which strictly speaking is not a coaxial power connector) is used aboard commercial airlines to provide electrical power to passenger's electronic equipment.
