Product Information
This 3 pin 5mm solderless connector provides an instant, secure power feed connection for narrow 5mm LED strip lights without requiring soldering equipment. Featuring a 12.5cm insulated 3-wire pigtail on one end and a compact piercing terminal block on the other, the unit measures 6.6mm wide by 5.0mm high to fit tight channels. It establishes electrical continuity through copper piercing blades that penetrate standard flex PCB solder pads when clamped down firmly with ordinary pliers. Engineered specifically for IP20 non-waterproof 3-pin flexible tape installations, this terminal resolves connection challenges on narrow-format circuits such as dual-white CCT and compact addressable layouts.
Key Features
5mm PCB Compatibility
Engineered exclusively for ultra-slim 5mm circuit boards, ensuring exact pad alignment where standard 8mm or 10mm terminals fail to fit.
Solder-Free Piercing Clamp
Hardened copper contact pins pierce through the flex PCB copper foil with standard pliers to form a gas-tight electrical bond in seconds.
12.5cm Integrated Pigtail
Supplied with pre-stripped 12.5cm lead wires to simplify links between the LED strip and terminal blocks, splitters, or power drivers.
Compact 6.6mm × 5.0mm Profile
Maintains an external shell footprint of 6.6mm width and 5.0mm height, allowing insertion into narrow aluminum extrusion diffusers.
3-Conductor Support
Carries 3 discrete circuit paths, making it suitable for dual-white tunable white channels and single-line addressable data arrays.

Application Scenarios
How to Use This Solderless Connector
- Cut the 5mm LED strip cleanly along its designated copper cut line using sharp shears or precision wire cutters.
- Check that the cut end is straight and flat, ensuring the 3 copper solder pads remain intact and undamaged.
- Insert the cut end of the 5mm LED strip into the connector opening until the copper pads align directly beneath the metal piercing teeth.
- Verify polarity and pin assignments: confirm that the wire colors match the corresponding V+, Data/Warm, and GND/Cool contacts on the LED strip.
- Take a pair of pliers and press the metal piercing teeth down evenly until they puncture the PCB and latch flush with the plastic housing.
- Perform a gentle pull test to confirm mechanical retention, then apply DC power to test electrical continuity.
⚠ Precautions
- Compatible strictly with 5mm wide IP20 flexible PCB LED strip lights; do not use with 8mm, 10mm, or 12mm boards.
- Not rated for waterproof or exterior use; do not use with silicone-sleeved, silicone-potted, or IP65/IP67/IP68 LED strip lights.
- Press down firmly and squarely across all 3 pins simultaneously to prevent incomplete pad penetration or tilted pin contact.
- Do not exceed the 3.0A aggregate current threshold to avoid thermal buildup across the internal piercing blades.
- Always disconnect the DC power supply before inserting, clamping, or adjusting the connector.

Frequently Asked Questions
Q: how to connect led light strips with connectors
A:Slide the cut end of your 5mm LED strip into the connector head so the copper pads sit under the metal contact pins, align polarity, and squeeze the metal pins down firmly with pliers until they pierce the circuit board.
Q: how to connect led strip light connectors
A:Ensure your LED strip is cut cleanly across the solder pads, insert the 5mm PCB into the connector slot until fully seated, check the pin matching, and clamp down on the pins using standard slip-joint or needle-nose pliers.
Q: how to fix led light strip connector
A:If a connection flickers or fails, inspect whether the piercing pins were fully crimped through the copper pads. Re-press the metal pins firmly with pliers, or trim 1-2mm off the LED strip end and crimp onto fresh copper pads.
Q: are led strip light connectors universal
A:No, LED strip connectors are not universal. This model fits only 3-pin non-waterproof LED strip lights measuring exactly 5mm in PCB width and will not fit 8mm, 10mm, or 12mm boards.
Q: Will this connector work on waterproof IP65 or IP67 LED strip lights?
A:No. This connector is engineered strictly for IP20 bare-board LED strip lights; silicone coatings prevent the housing from closing and stop the piercing pins from making electrical contact.
Q: What is the maximum current rating for this 3-pin connector?
A:The connector supports an aggregate current of up to 3.0A across its 3 conductors (approximately 1.0A to 1.5A per pin) over DC 5V to DC 24V installations.
Q: Do I need to peel off the 3M adhesive backing before inserting the LED strip?
A:No, the piercing pins are designed to penetrate through the flex PCB copper foil even with standard adhesive backing intact.
