The BH12 series from Hirose is a 20A current, compact, waterproof, signal and power hybrid connector ideal for use in E-mobility and Industrial applications.

It is available at distributor Anglia Components.

This connector is ideal for the battery connection of E-mobility and other industrial equipment such as autonomous factory robots.

It is an IPX6/IPX7 waterproof connector (when mated) with lock lever design and enhances cable wiring efficiency. Additionally, the power/signal hybrid design contributes to reducing connector occupied mounting space.

In recent years, the market for E-Mobility and autonomous robotic factory equipment has been expanding rapidly, and a variety of products have been developed to meet market needs. As a result, connection methods for connectors have also changed.

In particular, the connection of electric drive units is shifting from the conventional method of connecting the cable out of the panel with an in-line connector to the method of connecting connectors inside the application.

HIROSE has developed the BH12 series to address these applications, this smaller, high current, power-signal hybrid circular waterproof connector integrates their long experience in the E-Mobility and industrial robotics market.

The series features a compact design, although the total length is 36mm and the diameter is 13.8mm

The connector is compatible with 14 AWG size cables and can handle high currents up to 20A.

The hybrid power/signal design enables application size reduction because the connector occupied mounting space is reduced by combining power and signal in the same connector. The connector supports Power 20Ax2pos., Signal 1Ax2pos. (or Signal 1Ax1pos.). The power contacts on the receptacle side are soldered at a right angle, thus reducing the height requirement inside the panel.

A waterproof design (in the mated state) enable the connectors to handle direct water jets or total immersion under specified conditions, this allows the connectors to be used in harsh environmental settings.

The connectors feature a Lever lock for easy wiring, this can be locked in one action by simply pushing the plug straight into the receptacle. The lock lever on both sides of the plug prevents cable entanglement, lock deformation and damage during cable assembly and transportation. Guide keys are also available to ensure secure alignment and mating even in areas with poor visibility.

The BH12 receptacle is available in both front and rear mount types to suit the usage conditions. The front mount type is effective for reducing space used inside the panel, whilst with the rear mount type, pre-assembled cable assemblies can be attached to the panel. Additionally, screws are not visible from the panel exterior.

Operating temperature range is -40°C to +105°C

Applications include E-mobility (E-Bikes etc.), industrial robots, medical mobility equipment, LED lighting and many more.
