Specialist manufacturer in connectors, HIROSE Electric, has introduced its new robust lightweight circular EM30M Series. The series is suited to connect wind power generation systems, medical equipment, and factory automation machinery applications. The push-on bayonet lock saves users time and reduces the risk of electrical shock with the IP2X rated specification designed for contact touch protection against access to hazardous parts.

With the use of high-quality plastic material, the circular connector EM30M offers resistance to rough handling, for high current applications. In addition, the multi-point contact spring component helps reduce contact resistance and promotes a high current flow.

The connector series offers two options of non-waterproof or waterproof versions, the latter achieved with the IP67 specification, which provides superior levels of dustproof and waterproof protection due to the built-in O-ring capable of withstanding liquid intrusion. 

The EM30M series combines a simple push-on mating process with a bayonet un-mating mechanism. The connector is designed to lock simply by pushing the plug until the user hears an audible click, which is marked with triangles, making it easier for the user to visually line up the plug for blind mating. To un-mate the connector, the user simply twists the sleeve of the plug and pulls. 

A further benefit is that commercial tools are available to be used for this series. Termination of the crimp contact is quick and easy using standard JIS crimping tools. A contact removal tool is available to swiftly remove the contact from the housing.

In this way, the connector benefits from a bayonet locking system - electromechanical security, vibration resistance and positive sealing - whilst providing the simple operation of a push-on design.
