Hirose – Compact 160A power connector suitable for DIN rail or panel mounting


Hirose’s EF1 series of in-line power connectors are small but provide a 160A maximum current rating for use in demanding industrial applications.

The EF1 series consists of a DIN rail-mount in-line receptacle and plug and a panel-mount in-line receptacle and plug, both of which accept high-power crimp contacts.

The innovative connector design allows the crimped cable to be inserted into the connector housing in a quick and easy one-step operation. The crimp contact can be easily terminated to the cable with a standard 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 ensures the application of the optimum contact force to maintain a highly reliable and stable connection.

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