iButton Reader with white LED
Description
This iButton probe with LED 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. The solid metal contacts resist wear and are easy to keep clean.
The probe has no moving parts, making it a rugged interface for harsh environments. The round center contact of the ibutton probe houses the LED that is rated for maximum 20mA DC at 2.7V typical.
The probe comes with a brass nut for panel mounting. Since the body of the probe also forms the ground contact, the panel should be of non-conducting material to avoid ground loops. The 30cm cable with connector is provided for easy connection to the system microcontroller.
