18 Button and Activation Specifications
page 34 of 45 GU-139-Z1
The button requires a force of 3 -5 N (Newton - si units). Another way to explain this:
6 – 18 oz of pressure over time applied, which is between 125 –300ms (0.15 –0.3 seconds).
Slapping or sliding your fingers across the button will not activate it. It requires pressure over
time. The outer edge of the button will not be that sensitive. Normal use of the button would be
someone rushing to activate it and using their hand, finger, arm, knee, forehead, etc.
No other piezoelectric button on the market will function as well.
The only differences between the analog and IP buttons are the output on the wires and the
state of the button, N.O or N.C. The button can and piezo elements are identical. The analog
button (2 wire) is N.O. (Normally Open), and closes momentarily when pressed. The digital
button (3 wire) is N.C. (Normally Closed) and when pressed the state goes to open momentarily,
which is translated to a P then R data output to the IP1500/IP2500/IP5000 boards.
