This line of Mini-HMC heavy-duty connectors provides up to a 65% space savings for applications such as small robots, industrial controls, factory automation, production, and medical equipment. The Mini-HMC system is the first rectangular I/O connector system to offer a similar form and function as traditional heavy duty hard-shell connectors, but in a much smaller size. The company adapted and downsized some of the unique features of its existing line of HMC (Heavy Duty Modular) robotics connectors into the Mini-HMC system. A crescent-shaped metal hood with single action lock provides space savings and easy handling versus double bale-lock types. The “one-touch” spring lock also enables the lever to be smoothly engaged and locked firmly into place.
