The electronic key is a plastic part equipped with
a DS1990A „Touch Serial Number“ from
Dallas-Semiconductors and is used associated
with the magnetic probe 94-J-03. The key is held
magnetically to the probe and transmits the data
by an electrical interface. Please refer for all
electric data and the details of the electrical
interface (protocol timing and voltage) to the
data-book by Dallas-Semiconductors
The electronic key associated with the magnetic
probe is mainly used in electronic controled
beverage-systems, electronic cashier-terminals,
key-lock-systems and personal-computers. With
now seven different colors for the plastic body
the user can define different hierarchical
systems.
