## Summary description

Panel-mount DC barrel adapter by DELOCK (model 91120) converts a 5.5×2.5 mm plug to a 5.5×2.1 mm socket. Designed for fixed installation in equipment panels, it provides a reliable mechanical and electrical connection for DC power lines where plug size adaptation is required. Useful for adapting chargers, power supplies or cables without replacing existing wiring.

## Long description

DELOCK panel-mount DC barrel adapter 5.5x2.5 mm to 5.5x2.1 mm (model 91120) is a compact mechanical solution for adapting DC power plugs in fixed installations. It accepts an incoming 5.5×2.5 mm plug and provides a 5.5×2.1 mm socket mounted securely in a panel cutout. The adapter is intended for equipment panels, enclosures or cabinets where a reliable, space-saving conversion between common DC barrel sizes is required without modifying existing cables or power supplies.
Advantages
The adapter delivers a stable mechanical mounting and electrical contact for DC power connections while preserving the original cables and connectors. Its panel-mount design prevents strain on the internal wiring and allows a neat, secure installation. Because it converts between two widely used DC barrel dimensions, it reduces the need for replacement power leads and simplifies compatibility between chargers, power supplies and devices.
Suitable for
Adapting external chargers or power supplies to equipment with a different DC barrel size
Fixed installation in control panels, enclosures or cabinets
Field repairs or temporary conversions where replacing cables is not practical
Prototyping and lab setups requiring interchangeable DC connections
Key specifications
Input connector size: accepts 5.5×2.5 mm male DC barrel plug
Output connector size: provides 5.5×2.1 mm female DC barrel socket
Mounting type: panel-mount, designed for installation in a panel cutout
Contact type: standard barrel center pin and outer sleeve contact for DC power
Typical application: low-voltage DC power lines for chargers, adapters and devices
Construction: metal and/or plated contacts with insulating body for safe mounting
How to use
Prepare a suitable panel cutout according to the adapter outer dimensions, insert the adapter from the front side and secure it with the provided fastening method (nut or mounting ring) so that the connector is fixed flush to the panel. Connect the internal DC power wiring to the rear termination points following the device polarity (center positive or center negative as required). After installation, plug a 5.5×2.5 mm male plug into the adapter to receive power through the 5.5×2.1 mm socket interface. Verify correct polarity and secure electrical connections before energizing the system.
Usage recommendations
Use the adapter only for compatible low-voltage DC applications and ensure the mating plug dimensions match 5.5×2.5 mm for the incoming connector and 5.5×2.1 mm for the outgoing socket. Confirm voltage and current ratings of the connected power source and device are within safe limits for barrel-type connectors. Avoid excessive mechanical force on the mounted connector and periodically inspect contacts for wear or corrosion in demanding environments.
