Product details

Board-to-Board Header for Signal Interconnects

Right-Angle Mount for Board-Edge Routing

The unshrouded design with push-pull fastening means the header is intended for internal, low-vibration environments where a locking latch is not required.

Plating and Material Choices for the Build

The mating contacts are phosphor bronze with a gold GXT finish (30.0 µ" / 0.76 µm), while the solder tails receive a thick tin finish (100.0 µ" / 2.54 µm). This dual-plating strategy is standard for BERGSTIK headers: the gold side handles repeated mating cycles, and the tin side ensures reliable solder-joint wetting during wave or hand-soldering.

Frequently asked questions

What is the current rating of 55101-G1111LF?

The 55101-G1111LF is rated 5 A per contact. This is a signal-level current rating; the gold GXT plating on the mating interface supports repeated mating cycles without degradation.

What is the pitch of 55101-G1111LF?

The mating pitch is 0.100" (2.54 mm), which is the industry-standard spacing for BERGSTIK and compatible headers.

Is 55101-G1111LF RoHS compliant?

The part is listed as RoHS compliant per the manufacturer's specification.

Does 55101-G1111LF have a locking feature?

No. The fastening type is push-pull, meaning the header is unshrouded and relies on friction retention from the mating receptacle. It is intended for low-vibration internal applications where a locking latch is not required.
