EF1 Series, 160 Amps (max) In-line Power Connectors 



HIROSE has introduced the EF1 series to meet the requirement for smaller yet higher performing power connectors for industrial applications.


The EF1 series consists of a DIN rail mount type in-line receptacle and plug and a panel mount type in-line receptacle and plug which both accept high power crimp contacts with the capacity to handle up to 160A (amps) current rating.


The innovative connector design allows the crimped cable to be inserted into the connector housing in a quick and user-friendly one-step operation.  The crimp contact can be easily terminated to the cable with a standard market commodity JIS C 9711 hand tool.


The snap-in lock provides a positive tactile sensation to confirm correct mating engagement and secure connection. The unique shape of the internal spring contact and contact points allows the optimum contact force to maintain a highly reliable stable connection.


The housing features four different mating keying styles to prevent incorrect mating when multiple connectors are used. The connectors are available in a red colour to define the plus or minus connection.
