Unique-Bargains 2.1mm x 5.5mm DC Power Jack Female Panel Mount 5pcs

Panel-mount DC jack for 2.1 mm plugs

This 5.5 mm × 2.1 mm female panel-mount socket replaces a damaged power input on consumer electronics. Rated for a maximum of 30 V and 1 A, it suits audio players, cameras, remote controls, household appliances and similar low-power devices. Five connectors and five mounting nuts are supplied. It is not for buyers who need a higher current rating or a different pin diameter.

Check voltage current and mounting hole

Verify that the equipment operates at or below 30 V and draws no more than 1 A. Confirm the panel cut-out is 7.6 mm to match the M8 × 1.0 mm thread and that the mating plug uses a 2.1 mm centre pin. The jack is a through-panel type, so ensure there is access to the rear for the securing nut. Do not use if the application exceeds the stated voltage or current limits.

Thermals noise and power draw

With a contact resistance of 0.03 Ω the connector adds negligible heat at the rated 1 A load. The operating temperature range spans -30 °C to 70 °C, covering typical indoor and automotive environments. No active cooling is required and the passive component generates no audible noise. Insulation resistance of 100 MΩ and a withstand rating of 500 V AC provide a safety margin in normal use.
