DC power connector 2.1 mm OEM DCSV21 terminal block male, panel-mount plug, screw terminals

Compact male DC power connector DCSV21 with a 2.1 mm plug diameter designed for OEM applications and panel or chassis mounting. The connector combines a standard 2.1 mm DC barrel interface with screw terminal contacts to allow wire termination without soldering. It is intended for low-voltage power delivery to devices such as routers, cameras, LED drivers and small electronics, providing a removable, serviceable connection that simplifies installation and maintenance.

Advantages

The DCSV21 design offers a space-efficient panel-mount plug with screw terminals that enable quick field wiring and replacement. Using screw terminal contacts removes the need for crimping or soldering, which reduces assembly time and supports repairability. The 2.1 mm plug diameter conforms to common DC barrel sizes for compatibility with many external power supplies and adapters. The panel-mount form factor secures the connector to chassis or enclosure panels for stable mechanical support.

Suitable for

• Low-voltage power connections for routers and networking equipment
• Power input for CCTV and IP cameras
• LED drivers and small lighting modules
• Prototyping and small electronics where removable DC connections are required

Key specifications

• Connector type: male DC barrel plug
• Plug diameter: 2.1 mm
• Mounting style: panel / chassis mount
• Termination: screw terminal contacts for wire connection
• Application class: low-voltage DC power delivery for small electronics

How to use

Mount the DCSV21 plug into a suitable panel cutout and secure it according to your enclosure design. Strip the supply wires, insert them into the screw terminal openings and tighten the screws to ensure a firm electrical and mechanical connection. Verify polarity before applying power. Plug a matching 2.1 mm female barrel connector from the power supply into the mounted DCSV21 for normal operation. For maintenance or replacement, disconnect the external power plug and loosen the terminal screws to remove wiring.

Usage recommendations

Ensure correct polarity and use appropriate wire gauge for the expected current. Tighten terminal screws to a firm torque to avoid loose connections, and inspect mounting for secure panel seating. Use the connector within the intended low-voltage application range and in environments consistent with its panel-mount design.
