Mouser now stocks the Hirose Electric HR41A circular waterproof connector. The IP68-rated plastic-shelled connectors are designed to provide advanced reliability and high power use in a wide variety of harsh, outdoor environments. These include LED Lighting (tunnel lighting, street lamps, etc.), harsh-environment lighting such as industrial, construction sites, marine and agriculture, base station transceivers, robotics in wet environments and electronic toll systems The HR41A series consists of bayonet locking, cable mount plugs, and panel mount receptacles with the capacity to handle up to 10A. The five-position connector has a shell size of 17. The 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, says the company.
