New board-to-board connectors from Würth Elektronik eiSos for SMT assembly include the WA-SMST with a through-hole of 4.5 mm in diameter and the WA-SMSI with an M4 internal thread. Both versions are available for spacings of 1 to 10 mm in 1-mm steps.
The spacers are made of tinned-steel, and their large component diameters and the resulting large contact area guarantee high holding forces. The components withstand extraction forces averaging 610 N.
The SMD spacers are now available from stock in any quantity, loose or as a component reel. Free samples can be requested.
