iButtonTM Retainer

DESCRIPTION

The DS9098 iButton Retainer is a low-cost, surface-mount device that retains a 16.3 mm x 5.8 mm
MicroCan on a printed circuit board. The slender design secures the iButton for a compact printed circuit
board mount. The retainer latches the flange of the iButton and prevents reversed insertion.

PRECAUTIONS ON USE

At first insertion closely align axis of the iButton and the Retainer, and then apply approximately 10 kg
force for the separation of the center contacts. At subsequent insertion maintain similar axial alignment to
avoid permanent deformation. At removal, limit deflection of retainer latches to just free the iButton edge
from retained state. Avoid applying excess force to latches.
