The Amphenol ICC 93939-120HLF is a 20-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board signal interconnect. It uses a 0.100" (2.54 mm) mating pitch with the same row spacing, giving a standard footprint for prototyping or production. The right-angle through-hole orientation places the pins parallel to the PCB, which suits board-edge routing in enclosures where vertical clearance is tight. Rated 5 A per contact at 110 V, it handles typical logic-level and low-power signal duty without issue. The mating contacts carry 30.0 µin gold plating, which supports repeated mating cycles better than tin — a practical consideration if the board goes through test, rework, or field service. The housing is rated UL94 V-0, meeting the flame requirement for equipment inside an enclosure. Contact material is phosphor bronze, a standard spring alloy that holds up to insertion and extraction over the connector's service life.
Within the BERGSTIK® II family, the 93939-120HLF has 20 positions at a 0.100" pitch in a dual-row layout.
This unshrouded header mates with any standard 0.100" pitch dual-row receptacle, such as the BERGSTIK® II socket strip or a compatible IDC socket. The push-pull fastening means no locking latch — the retention comes from the contact normal force, so the mated pair is best used in a stationary assembly where vibration is controlled. For a field-mateable or high-vibration application, a shrouded header with a latch would be a better fit.
