What this 2-position shrouded header does for your board
The 2213933-2 is a 2-position, right-angle, shrouded header from TE's WireMate / TB / Buchanan series, built for terminal block applications that need a secure, keyed connection on a 0.138" (3.50mm) pitch.
At 0.138" (3.50mm) pitch with 2 positions, this header matches the footprint of a 2-circuit terminal block plug — the right-angle orientation places the wire entry parallel to the PCB, saving height in a shallow enclosure. The surface-mount termination and UL94 V-0 rated thermoplastic housing suit it for reflow assembly in equipment that needs a flame-rated connector.
