## Summary description

Synergy21 S21-LED-000220 is a wire connector designed for DC 2.1 x 4 mm power plugs. Supplied in black and green, it provides a compact connection solution for low-voltage LED systems and other DC-powered devices using the 2.1 x 4 mm plug standard. Suitable for assembly, repair, and installations requiring a reliable DC inline connection.

## Long description

Synergy21 S21-LED-000220 is a recessed wire connector designed for DC 2.1 x 4 mm power plugs and intended for panel or fixture mounting in LED lighting assemblies. The compact recessed socket provides screw terminal connections for reliable wiring of LED modules and housings, allowing serviceable, low-profile integration where a stable inline DC connection is required.
Advantages
The recessed construction minimizes protrusion from the fixture surface while maintaining secure electrical contact via screw terminals. Screw connections enable straightforward installation, secure clamping of solid or stranded conductors, and simplified maintenance or replacement without the need for soldering. The socket’s form factor and terminal design support common LED module wiring practices and facilitate retrofit or new lighting assemblies.
Suitable for
Panel or housing mounting of LED modules
Fixture assemblies that require a compact, serviceable socket
Retrofit LED installations and replacement modules
Applications needing screw-terminal connections for solid or stranded conductors
Key specifications
Compatible plug standard: DC 2.1 x 4 mm barrel connector
Mounting type: recessed panel or fixture mount
Connection method: screw terminal connections for conductor clamping
Form factor: compact recessed socket to reduce external projection
Color: black/green
How to use
Prepare a panel or fixture cutout sized for the recessed socket and insert the component into the mounting location. Route the supply and LED module conductors to the screw terminals, strip insulation to the appropriate length, insert the conductor into the terminal and tighten the screw to secure the connection. Verify correct polarity of the DC 2.1 x 4 mm connection and ensure mechanical retention of the mating connector before applying power. For maintenance or replacement, loosen the terminal screws to remove conductors and replace parts as required, then recheck connections and polarity prior to re-energizing the circuit.
Usage recommendations
Use conductor sizes appropriate for the terminal clamp and follow the lighting assembly’s recommended torque values for screw tightening. Confirm the socket’s physical fit and compatibility with the LED module and mating DC 2.1 x 4 mm connector prior to installation, and perform continuity and polarity checks after wiring.
