Wire connector Synergy21 S21-LED-000219 for DC 2.1 x 5.5 mm plugs, black/green, 13.9×38.5 mm, 5.5 g

Synergy21 S21-LED-000219 is a wire connector designed for DC 2.1 x 5.5 mm plugs, providing a compact, removable interface for low-voltage LED systems and small consumer electronics. The connector measures 13.9 × 38.5 mm, weighs 5.5 g and is offered in black and green. It combines a hollow-plug form factor with tool-accessible screw terminals to enable secure mechanical and electrical connections without soldering, suitable for indoor lighting, repairs and prototype work.

Advantages

The hollow-plug design allows quick insertion and removal of mating parts while screw terminals deliver a reliable low-resistance electrical contact. The screw-clamp mechanism accepts a range of copper conductor cross-sections and provides repeated assembly capability for maintenance or rework. Its insulated housing and metal contacts ensure electrical continuity and mechanical stability in low-voltage DC applications.

Suitable for

• Connecting LED strips and modules in indoor lighting installations
• Repairing or replacing LED components where a removable connector is required
• Prototype development and bench testing of LED circuits
• Small-scale lighting projects that require screw-terminal connections

Key specifications

• Connector type: hollow plug with screw terminals
• Compatible plug size: DC 2.1 × 5.5 mm
• Dimensions: 13.9 × 38.5 mm
• Weight: 5.5 g
• Contact method: screw-clamp for copper conductors
• Intended voltage: low-voltage DC systems (LED applications)
• Housing: insulated plastic with metal contacts

How to use

Strip the conductor insulation to the recommended length, insert the bare copper conductor into the screw terminal and tighten the screw to secure the wire. Insert the mating DC 2.1 × 5.5 mm hollow plug or LED module into the connector body until it seats firmly. Verify mechanical retention and check electrical continuity before applying power. To disconnect or rework, loosen the screw to release the conductor and remove the mating plug.

Usage recommendations

The connector is intended for indoor, low-voltage LED applications; avoid exposure to moisture, condensation and elevated temperatures. Use appropriately sized copper conductors and tighten screws to a secure torque to prevent loose contacts. Inspect connections periodically in installations exposed to vibration or frequent handling.
