BergStik 2.54mm unshrouded headers mating cycle up to 100 breakaway design Amphenol 68021-406HLF connector product
BergStik 2.54mm Unshrouded Headers
Product Overview
BergStik 2.54mm pitch unshrouded headers offer versatile Board-to-Board, Wire-to-Board, and Cable-to-Board interconnect solutions for a wide array of electronic equipment and devices. Available in surface-mount (SMT), through-hole (THT), press-fit, stacking, and pin-in-paste (PIP) versions, these headers are designed in single and double rows with straight or right-angle options, ranging from 2 to 72 positions. Their 'breakaway' design allows for custom length adjustments. The range includes vertical headers in standard and special sizes, continuous headers, and stacking headers, providing economical and flexible solutions for various application profiles. The maximum current rating per contact is 3A, with a specified mating cycle of up to 100 cycles for certain configurations.
