DESCRIPTION
Unlike conventional keypads, where data is entered by pressing a mechanical key, the solid buttons of an
iButton keypad allow users to enter data by simply touching each button with an iButton probe or
handheld computer. Each of these buttons comes from the factory with blank memory, allowing the user
to program each button with whatever data the user would like entered when touched. The i
keypad is a simple, robust alternative for data entry in harsh environments such as outdoors, industrial
workplaces and other locations, where a normal keypad is impractical to operate. Since i
Buttons are made
from stainless steel, this keypad is easily cleaned with hot water and detergent.
The individual iButtons that comprise the keypad can be arranged as desired to maximize ease of use.
They can be stuck on a smooth surface using adhesive pads or mounted through 16.5mm holes in a rigid
material and fastened by lock rings. The material thickness should not exceed 3.0mm. For a detailed
description of the communication protocol and the electrical characteristics of the iButton used in this
keypad, refer to the DS1982 data sheet.
