Hirose Electric — HR41 Circular Connector

The Hirose HR41 series of high-current circular connectors is ideal for use in outdoor, harsh environments.

The lightweight circular housing is robust and resistant to harsh environmental conditions. Tests verify its reliability in the presence of:

• Sunlight: tested for 2,000 hours of operation
• Salt spray: tested for 1,500 hours of operation
• Water intrusion: IP68 rating

In addition, the HR41 connectors withstand 15 kV lightning surges.

The connector range consists of bayonet-locking, cable-mount plugs, and panel-mount receptacles which can handle currents up to 24 A. The HR41 provides for easy field assembly with a standard crimp tool. A visual and tactile raised mating indicator on the plug and receptacle aids the mating operation in dark conditions.

The cable can be clamped and the waterproof gasket sealed in one simultaneous step without additional tooling. The anti-loosening mechanism ensures that the tightening ring securing the cable will not come loose during operation.

The innovative connector design incorporates a sequential contact structure. The contacts are arranged in sequence so that the ground contact is connected before the power contacts during the mating process, ensuring safe connection. In addition, housing walls protect the contacts and ensure a long creepage distance.

A contact removal tool is available to quickly remove the contact from the housing.
