Vantage explosionproof connectors are often mounted on mobile equipment and subject to extreme environments. Prior to coupling a plug to a receptacle, it is necessary to visually inspect the front face of the connector to ensure it is free of contaminants that might obstruct a clean connection. In certain cases, it is recommended to perform a Mate Check Test before each connection. A Mate Check Plug replicates a complete mating cycle, but is easily repairable in case a pin is bent or damaged during introduction to the receptacle. This Mate Check Test verifies that a receptacle is fit for use.
