Product details

The Amphenol FCI BERGSTIK 55101-S1120LF is a 20-position single-row unshrouded header on the standard 0.100" (2.54 mm) pitch. Rated 5 A per contact at 110 V, with gold or GXT plating on the mating face at 15.0 µin and a tin finish on the solder tail.

As an unshrouded header, this part mates with any standard 0.100" (2.54 mm) pitch female receptacle — IDC ribbon cable sockets, discrete crimp housings, or board-to-board receptacles. The square male pins measure 0.230" (5.84 mm) on the mating side and 0.090" (2.29 mm) on the post side.

Frequently asked questions

What is the pitch of 55101-S1120LF?

The pitch is 0.100" (2.54 mm), the industry-standard spacing for breadboard-compatible headers and IDC ribbon cable connectors.

Does 55101-S1120LF have a locking mechanism?

No — the fastening type is push-pull, meaning there is no latch or locking ramp. The mating pair relies on friction fit and is not rated for high-vibration environments without additional retention.

What is the current rating of 55101-S1120LF?

Rated 5 A per contact at 110 V, with the current limit set by the contact and housing temperature rise at the stated voltage.
