It uses a 0.100\" (2.54 mm) pitch on both rows and contacts, which is the standard footprint for legacy and current through-hole PCB layouts. The right-angle orientation places the pin rows parallel to the board, making it a natural fit for daughtercard or mezzanine connections where the cable or board-to-board path runs along the edge. ## Key Specs and What They Mean for the Fit Rated 5 A per contact at the stated voltage of 110 V. The 5 A figure is typical for a 0.100\" pitch header with gold-plated contacts — it handles logic-level power and signal distribution without thermal issues, but it is not a bus-level power rail. The 30.0 µin gold on the mating surface is the spec that matters for repeated mating: that thickness supports hundreds of cycles before the contact resistance starts to drift, so this header is a solid choice for applications that see periodic reconnection during field service. The unshrouded design means there is no plastic wall around the pins — the header exposes the full pin length for probing or for mating with a standard IDC socket or a shrouded receptacle. The push-pull fastening is the default for unshrouded headers; retention comes from the friction of the mating contact, not a latch. For a vibration-prone environment, a mating half with a locking ramp would be the better pairing. UL94 V-0 rated housing — the black insulator meets the flame-retardant requirement for equipment inside an enclosure. The through-hole solder termination is a proven, inspectable joint for prototype and production runs alike.","metaTitle":"Amphenol 93939-112HLF BERGSTIK II Header, 12 Pos","metaDescription":"Amphenol 93939-112HLF BERGSTIK® II unshrouded header, 12 positions, 0.100\" pitch, 5 A, gold-plated contacts.
