Connectors deliver current density for long-life applications

Interconnect manufacturer Molex has expanded current-carrying capabilities up to 23A with its new Mega-fit power connectors, now available in Europe at TTI Europe. The new power connectors provide far higher current density than existing mid-range power connectors and incorporate many features characteristic of their power products, including isolated terminals, polarised housings and positive housing locks. The 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 5.7mm pitch connectors incorporates high-current terminals and tight pitch and row spacing, claiming 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 23A, electrical specifications include maximum voltage of 600V and contact resistance of 6milliohms. As there are six independent points of contact, the four redundant or sacrificial contacts allow the system to be “hot plugged” at 48V/23A 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, the 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 these 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.
