Solderless 5.5 x 2.1mm Female Barrel Connector

This 10-pack of JacobsParts LSA-N-10PK connectors joins standard barrel power adapters to 10mm two-conductor LED strip lighting without soldering. The female barrel jack accepts a 5.5mm outer and 2.1mm inner diameter plug. Each unit uses a hinged clamp that opens for strip insertion and closes to secure the connection. They are intended for single-colour SMD5050 strips.

Solderless clamp for 10mm two-wire PCB strips

The decisive specification is the solderless clamp design that grips 10mm wide, two-conductor flexible PCB strips. No iron, flux or wire stripping is required; the installer opens the top, slides the strip under the contact pins observing polarity, and snaps the cover shut. This mechanical connection replaces solder joints and enables quick reconfiguration of cut reel sections.

Installers extending or splitting single-colour

These suit anyone adding barrel-input power to existing 10mm single-colour SMD5050 tape or dividing one reel into several powered segments. They do not address RGB, RGBW or addressable strips that need three, four or more conductors. Buyers needing waterproof IP-rated junctions, screw-terminal blocks or connectors for wider PCB widths should look at other styles.

Questions about this item

How does the 5.5 x 2.1 mm barrel size work with my power adapter?

The connector accepts the common 5.5 mm outer and 2.1 mm inner diameter barrel plug found on many LED strip power supplies, giving a direct solderless link to the strip.

What does the 10 mm 2-pin strip specification mean for installation?

It fits 10 mm wide two-conductor PCB strips used with single-colour SMD 5050 LEDs; open the clip, slide the strip under the contacts, and close to lock it in place.

What physical space does each connector need behind the strip?

Each low-profile barrel jack adds only a few millimetres of depth behind the 10 mm strip, so it fits inside standard aluminium channels or tight coves without protruding.
