Power connectors get current density boost
The current-carrying capabilities of Molex’s new Mega-fit power connectors have been extended to 23A per circuit. They are available in Europe at TTI. The power connectors provide far higher current density than existing mid-range power connectors and incorporate many features characteristic of Molex power products, including isolated terminals, polarised housings and positive housing locks.
Mega-Fit power connectors feature a patented split-box terminal design which offers six independent points of contact to provide long-term reliability through secondary current-path redundancy.
The power-dense split-box terminal design of 5.70mm pitch Mega-Fit power connectors incorporates high-current terminals and tight pitch and row spacing to produce more power per linear and square millimeter than any other mid-range power product currently available on the market.
As well as maximum current of 23.0A, electrical specifications include maximum voltage of 600V and contact resistance of 6 milliohms. As there are six independent points of contact, the four redundant or sacrificial contacts allow the system to be “hot plugged” at 48V/23.0A for up to 30 cycles.
Further features include an extended barrel conductor crimp providing extremely strong terminal-to-wire retention, offering the assurance of long-term reliability. Fully isolated header pins and receptacle terminals protect against any potential damage during handling and mating.
To confirm that the receptacle and header are securely retained, Mega-Fit power connectors have positive locking housings which make an audible click when in the correct mating position.
There are a very wide range of applications for Molex Mega-Fit power connectors across multiple industries, including: industrial machinery and heavy equipment; industrial lighting and automation; unsealed electronic control modules and power converters in commercial vehicles; networking and telecommunication hubs, servers, power supplies, and distribution equipment; consumer home appliances, such as washers, dryers, heaters and air conditioners.
