FEATURES
Simple, low-cost metal stampings form a
read/write probe for the iButton family
Probe guides the entry of the iButton
iButton slides over the surface to self-clean
contacts
Accessible shallow probe cavity simplifies
removal of debris such as mud
Flexible design supports panel mount or
hand-grip mount with optional tactile
feedback
Bright tarnish-resistant metal surface provides
millions of operations
Panel-mount probe, pre-wired for easy
installation
Hand-grip probe mates to RJ-11 jack for
quick installation
DS9092 probes both F3 and F5 cans. Extra
consideration is required for operation with
the F3 can. The attachment method of the F3
can must not interfere with the cavity
dimensions of the probe, otherwise the data
signal will not make contact.

DESCRIPTION
The DS9092 iButton Probe provides the electrical contact necessary for the transfer of data to and from
the DS19xx family of iButtons. The round probe shape provides a self-aligning interface that readily
matches the circular rim of the iButton’s MicroCan package. Metal contacts resist wear and are easy to
keep clean.
Pin Configurations appear at end of data sheet.

environments. This type of probe is best suited for designs where the iButton is brought into contact with
the reader.
The tactile feedback probe is ideal for situations where the iButton is stationary and the movable reader is
brought in contact with it.
Both types of probes are available in a panel-mount version. The tactile feedback probe is also available
in a grip-mount version. The panel-mount probes are fastened behind the panel with a push-on type
spring nut.
The two 15 cm 22AWG wires are provided for easy connection to the system microcontroller. The hand-
grip mount probe comes attached to a 10 cm handle and 1-meter cable which is terminated with an RJ11
jack.
