High Amperage Jacks and Plugs Switchcraft High Amperage Power Jacks and Plugs provide more than twice the industry standard power capability - up to a full 11A or 24VDC. Design engineers and manufacturers want and need ways to get higher current through the connector interface. Using high amperage power plugs and jacks is an effective way to do just that. They are available in in locking or non-locking and sealed or unsealed versions. The sealed version are rated to IP68. The High Amperage Power Jacks and Plugs feature an automatic switch over from AC to DC permitted by sleeve shunt spring and an operating temperature -40°C to +105°C. Use high amperage power plugs and jacks to design more powerful, more compact instrumentation and to streamline the regulatory and product approval process.
