20-position breakaway header for board-to-board or cable duty
The 9-146261-0-10: The breakaway construction means the 20-position strip can be snapped to shorter lengths if needed, though this variant is loaded with all positions. The unshrouded design lacks a polarization key, so the mating receptacle's housing provides alignment — confirm the receptacle's keying and latch features before committing. The tin-plated solder tails (100 µinch) suit standard wave-solder processes.
Gold mating finish and UL94 V-0 housing
The 30 µinch gold over nickel on the mating face is rated for 500 mating cycles minimum — in a field-service application where the connector is cycled quarterly, that is over a century of service life at the contact interface.
