INSERTION OF iButton

DESCRIPTION

The DS9094 Clip holds an iButton and connects to a printed circuit board. By deflecting the spring clip in the molded housing, an iButton can be inserted and ex- tracted without special tools. If reverse insertion is at- tempted, the beveled edge on the housing prevents contact. The DS9094’s low profile minimizes the clear- ance height above the printed circuit board.

NOTE:

Due to the large variation of cycles and temperatures in reflow ovens, it is recommended to experiment with this clip first before using it in production. If guaranteed compliance with the reflow soldering process is required, the DS9098 iButton Retainer should be pre- ferred.
