XLR Connector Male

Description

4mm Insulated Banana Female Socket (Panel Mount Binding Post) The 4mm Insulated Banana Female Socket is an industry-standard electrical connector used heavily in test equipment, power supplies, and audio amplifiers. Designed to accept a standard 4mm banana plug, this socket features a fully insulated nylon or PVC outer shell that prevents accidental short circuits and protects users from electrical shock during high-voltage or high-current testing. It typically includes a chassis-mounting thread, a securing hex nut, and a metal solder tab or screw terminal at the rear for internal wiring. Key Features Connector Type: 4mm Banana Female Jack / Binding Post. Safety Insulation: Encased in a rugged, fully insulated plastic or nylon shroud to safely handle higher voltages (often rated for CAT II or CAT III safety standards depending on the manufacturer). Color-Coded Housing: Typically available in standard Red (Positive/Live) and Black (Negative/Ground) for instant polarity identification. Mounting Design: Threaded panel-mount body with a rear hex nut and lock washer to ensure a tight, vibration-resistant fit on metal or plastic enclosures. Termination: Features a rear solder bucket, flat solder tab, or a threaded nut setup for secure internal wire attachment. Compatibility Guide This socket is a staple component in electrical engineering labs, testing facilities, and custom power distribution builds. 1. Compatible Inputs (Front Side) Standard 4mm Banana Plugs: Accepts all standard single, stackable, or shrouded/safety 4mm male banana plugs. Multimeter Probes: Perfectly fits the standard 4mm output leads coming from digital multimeters (Fluke, Keysight, Klein Tools). 2. Compatible Equipment & Applications Benchtop Power Supplies: Used as the primary output terminals on custom variable DC power supplies and lab equipment. Test and Measurement Jigs: Integrated into custom component testing boards, break-out boxes, and school physics lab equipment. Loudspeakers & Amplifiers: Functions as a premium speaker binding post on high-fidelity audio amplifiers and passive speaker cabinets. Electronic Prototyping Benches: Mounted onto custom console panels to easily route power lines down to breadboards or prototyping plates. 3. Installation Requirements Panel Cutout: Requires a standard circular chassis panel hole (usually approx. 8mm to 12mm depending on the specific thread diameter). Tools: A standard drill bit for the panel cutout and a soldering iron to secure the internal hookup wire to the rear tab.
