SMA Female to U.FL / IPEX RF Pigtail Cable (10cm)

Prototyping and Engineering Tips from Robogears

• The U.FL "Snap" Test: U.FL connectors are very delicate and are only rated for a few dozen connection cycles. When attaching it to your module, use a wooden stick or a specialized U.FL insertion tool to apply straight downward pressure. You should feel a distinct "click." Never pull the connector by the wire to remove it; always use fine-point tweezers to lift the metal head.

• Strain Relief: Since the cable is very thin (1.13mm), it can snap if pulled. Once connected, use a tiny drop of hot glue or a piece of Kapton tape near the U.FL connector to act as a strain relief, ensuring that external tugs on the SMA end don't rip the U.FL connector off your PCB.

• Panel Hole Size: To mount the SMA Female bulkhead, you will need to drill a 6.5mm hole in your enclosure. Ensure the surface is flat so the washer can create a proper seal.

• Signal Loss: At 2.4GHz, every centimeter of cable introduces a small amount of signal loss. 10cm is the "sweet spot" for most handheld projects, providing enough length to move around without significantly degrading the signal strength.

Package Includes

• 1 x SMA Female to U.FL (IPEX) Connector - 10cm

• 1 x Mounting Nut

• 1 x Lock Washer

Disclaimer

This is an SMA Female connector (with a hole in the center). Ensure your antenna is an SMA Male (with a pin in the center). If your antenna has a hole in the center, you need an "RP-SMA" cable instead. Always verify the connector gender before purchasing to avoid mismatching.
