iButton Reader / iButton key probe with white LED for DS1900A
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 matcheHydraulic Tool s 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.Key FeaturesSolid metal read/write panel-mount probe for the iButton family

An iButton is a microchip similar to those used in a smart card but housed in a round stainless steel button of 17.35mm x 3.1mm - 5.89mm in size (depending on the function). The iButton was invented and is still manufactured exclusively by Dallas Semiconductor mainly for applications in harsh and demanding environments. Like a smart card, an iButton does not have an internal power source. It requires connection to a reader (known as a Blue Dot Receptor) in order to be supplied with power and to receive input and send output. Unlike some smart cards, there are currently no contactless iButtons: they require physical contact with a reader to function. There are iButtons that measure temperature (for food storage and transport); have an electronic ID (for physical access to buildings); and store e-cash (for purchases both in stores and via the web). For e-commerce applications, the iButton can support JavaCard 2.0/OpenCard standards in addition to proprietary software. iButtons have an advantage over conventional smart cards in term of durability and longevity. The stainless steel casing gives iButton a far greatMixing Equipment er ability to survive in a range of temperatures -- all versions are functional from -40 C to +70 C -- and in a much harsher range of environments (such as exposure to salt water and long term exposure to physical impacts) than the plastic smart card. For e-commerce and personal ID usage, iButtons can be mounted on a range of personal accessories: watch, ring, key chain, or dog tag. Among the major successes for the iButton have been its use in Turkey as an e-purse for the mass transit system; in Argentina and Brazil for parking meters; and in the United States as Blue Mailbox attachments that improve postal efficiency.
