    Speakon Panel Mount Connector

    Stock Code: SP-4-MD

    75C -25C
    IP CODE 40
    Opens a four-contact speaker inlet on the cabinet panel
    An SP series panel mount loudspeaker connector that forms a fixed speaker inlet on the panel of amplifier and speaker cabinets. The chassis end goes to a printed circuit board or to 3/16 inch solder tabs.

    Key features
    5000cycles
    Long mechanical life
    The panel mounted connector is rated for repeated mating and unmating.
    1500V
    Strength between contacts
    The insulation withstands the AC RMS test voltage.
    ≤3mΩ
    Low contact resistance
    Silver-plated phosphor bronze contacts hold transfer resistance down.
    ≥2GΩ
    Insulation that survives damp
    Initial resistance; after the damp heat test it stays above 1 GΩ.
    UL94HB
    Insulating body material
    The shell and the insulators carry this flammability rating.
    On the panel
    Fixed inlet pointIt forms a permanent inlet on the cabinet panel while the cable side stays on the plug.
    Two wiring routesThe chassis end either sits on the board or runs from a solder tab.
    Inside a closed cabinetThe protection level targets dry and enclosed installations.
    Electrical, climatic and mechanical figures are defined for the SP series as a whole in the product document; some rows change with contact count and housing variant.
