To meet the increased demand for high-powered connectors offering advanced reliability for industrial equipment, Hirose has introduced the EM range, comprising of plugs and receptacles that have the capacity to handle 50 A.
The connector design incorporates three 50 A power contacts and one ground contact. The contacts are arranged in sequence to ensure the ground contact is connected before the power contacts during the mating process. A special spring in the receptacle connector connects the ground contact to the metal shell for reliable panel grounding. A further feature is a special protective cover over the female contacts that minimises the exposure of the contact area to possible damage. Termination of the crimp contact employs standard JIS crimping tools. A contact removal tool is available to quickly remove the contact from the housing.
Waterproof protection is guaranteed with special gaskets strategically placed at each connection point of the connectors in the mated condition. The high water resistance performance meets with IP67, allowing the EM series to withstand submergence in 1,8 m water for 48 hours in its mated condition. The EM35 has five polarising keys in the mating face to ensure correct mating positioning and stability against vibration.
The one-touch bayonet locking mechanism securely locks the mated connectors; this works by turning the outer collar on the plug with a clockwise quarter turn to mate the connector and a quarter turn counter clockwise to disconnect. Correct mating is confirmed with an audible tactile click.
