DC power socket 2.1 mm female terminal block OEM DCSV21FEM

The DC power socket 2.1 mm female terminal block OEM DCSV21FEM is a compact panel-mount connector designed for low-voltage DC power input. It features a 2.1 mm female barrel contact combined with a screw terminal block for wire connection without soldering. Intended for embedded installation in electronic devices, the connector provides a simple interface for external adapters and cables to supply power to consumer electronics, instruments and accessories.

Advantages

The design combines a standard 2.1 mm female DC barrel contact with a screw terminal block, enabling tool-secure wire termination and easy replacement of power jacks. Its compact footprint suits confined enclosures while the panel-mount format ensures stable mechanical fixation. Because it accepts common adapter plugs, the socket facilitates fast assembly and maintenance of power connections.

Suitable for

• Embedded electronics and small appliances requiring a 2.1 mm DC inlet
• Prototyping and repair work where solderless wire termination is preferred
• Devices and enclosures with limited panel space for power connectors
• Low-voltage power distribution for instruments, chargers and accessories

Key specifications

• Connector type: 2.1 mm female DC barrel contact with screw terminal block
• Mounting style: panel/flush mounting for built-in installation
• Wire termination: screw terminals for stranded or solid conductors
• Contact gender: female (receptacle)
• Typical application voltage: low-voltage DC systems (adapter-compatible)
• Mechanical footprint: compact design suitable for limited-space enclosures

How to use

Mount the connector into the panel or enclosure cutout and secure it according to the device mechanical requirements. Strip the insulation from the supply wires, insert conductors into the appropriate screw terminals, and tighten the terminal screws to ensure a firm electrical and mechanical connection. Insert a compatible 2.1 mm DC plug from an external adapter or cable to provide power to the device. Verify polarity and that connections are secure before applying power.

Usage recommendations

Use appropriately rated wire sizes for the expected current, confirm the adapter output matches the device voltage and polarity, and avoid over-torquing terminal screws to prevent damage to conductors or the terminal block. For repeated plug cycles, ensure the panel mounting is secure to prevent mechanical strain on the solderless terminals.
