Hirose Electric HR41A Circular Waterproof Connectors are IP68 rated, plastic-shelled connectors designed to provide advanced reliability and high power use in harsh, outdoor environments. The HR41A series consists of bayonet locking, cable mount plugs, and panel mount receptacles with the capacity to handle up to 10A. The 5 position connector has a shell size of 17. HR41A's sequential contact structure is designed to connect the ground contact before the power contacts during the mating process as an additional safety measure. In addition, the lightweight housing is resistant against harsh environmental conditions, such as sunshine (tested with 2000h), salt spray (tested with 1500h) and water intrusion (IP68 rated). HR41A is also resistant against 15kV lightning surges due to the special wall structure.
