In-line power connectors shrink for industrial applications

The EF1 series of in-line power connectors has been released by Hirose, to meet the requirement for smaller yet higher performing power connectors for industrial applications.

 The EF1 series consists of a DIN rail mount 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 current rating.

The design allows the crimped cable to be inserted into the connector housing in a quick, 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 confirmation of the correct mating engagement and secure connection. The shape of the internal spring contact and contact points allows the optimum contact force to maintain a 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.

There are one contact positions and the connector has an operating voltage of 1,000V AC/DC. Operating temperature range is -25 to +105 degrees C.

Suitable applications are power controllers, inverters, storage battery, medical devices and robot controllers.
