Neutrik - NL2FXX-W-S

This 2-pole speakON connector is designed for audio cables and is ideal for loudspeaker connections in professional environments. Its design includes screw terminals for wire connection and a twist-lock system that ensures a secure and stable connection. It is suitable for cables with diameters between 6 and 12 mm and supports high currents, making it an ideal choice for high-power audio systems.

Its construction is solid and designed to last, with materials such as copper alloy for the contacts, polyamide for the body, and a zinc die-cast locking element. Its electrical and mechanical characteristics include very low contact resistance, high insulation resistance, and an average lifespan of approximately 5000 connection cycles.

N.B. This connector is not intended for use as an AC power connector.

Main features
