Hirose HR43 Series Bayonet Lock Connectors

HR43 series bayonet lock connectors

Hirose has introduced the HR43 range to meet with the requirement for connectors with advanced reliability for railway applications and other harsh environments.

The cable mounted plug and panel mount jack allow an in-line connection. The current handling capacity is 20A (amps) per contact.

The connectors are constructed of aluminium alloy to allow them to be lightweight yet robust to withstand vibration and shock. The user-friendly bayonet lock ensures a secure connection.

The simplified assembly procedure allows the unique waterproof gasket to be sealed and the cable clamped simultaneously by the tightening ring without the need for additional tooling. This reduces the components needed and saves time. The unique waterproof gasket surrounds each individual wire to seal it and provide IP67 waterproof protection in the mated condition.

The HR43 is optimised for easy field assembly with a standard market commodity hand tool to terminate the crimp contacts. A contact removal tool is available to quickly remove the contact from the housing.
