FEATURES
Compact single–piece, all–metal receptacle for
iButton mounting
Retainer withstands high temperatures required for
surface mounting
Center contact is permanently separated at first inser-
tion of the iButton

DESCRIPTION
The DS9098 iButton Retainer is a low–cost, surface
mount device that retains a 16.3mm x 5.8mm 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 pre-
vents 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 per-
manent deformation. At removal, limit deflection of
retainer latches to just free the iButton edge from
retained state. Avoid applying excess force to latches.
