speakON connector - Neutrik NL4MPRXX

The NEUTRIK NL4MPRXX is a panel-mount speakON connector for loudspeaker and amplifier links: robust, versatile receptacles that are straightforward to terminate. It meets device standard IEC 62368-1 through component certification to IEC 61984.

This 4-pole chassis unit has a black round G-size flange, countersunk thru holes, and 3/16" flat tabs. A unique metal locking system closes the electrical path only when fully locked. Glass-reinforced V-0 materials add strength; a precise keyway guides mating; an accurate twist-lock latch and metal insert in the locking zone secure the fit. An airtight layout suits loudspeaker applications. speakON must not be used as an AC mains or power supply connector.
