Anti Spark connectors are designed for connection between drive battery and electric motor controller. These connectors are equipped with a circuit to limit the charging current to the capacitors of the controller and thus prevent electrical discharge when connected. By eliminating the occurrence of an electric shock, the service life of the connector in terms of the number of connections and consequently the reliability of the connection is significantly increased. Anti Spark connectors are further characterized by low transient resistance and especially by their ease of use. Diameter of connector is 7mm.
