Micro Touch
Screen Comparison
(06/19/08)
With the advent of various
manufacturers offering micro touch screens, we
thought a comparison would be in order.
Are all micro touch screens
the same?
Do they offer the same
capabilities?
Entertron is promoting the
Beijer touch screen. See how it compares to other
manufacturer's products
We will look at the Beijer
H-Series unit vs. AVG, and Automation Direct
Note - These comparisons do
not take into account any special pricing
promotions or quantity discounts. All information
was obtained from published specifications.

| Conclusion |
| The
H-T40 may be a little more expensive, but
you receive better touch capabilities, a
Real Time Clock and an enormous amount of
memory for your application. Throw in the
cable if you are using an Entertron PLC
and it is an extremely competitive
combination. |
| The
H-T40 includes a real time clock. In that
it isn't included in the touch screen, it
would therefore need to be added to the
PLC. For most PLCs, this is an additional
cost. |
| The
H-T40 provides analog resistive touch
rather than cell touch. This allows for
greater flexibility in placing objects in
your project |
| When utilizing
Entertron's ePLCs, and a Beijer's touch
screen, we provide the interface cable
with the controller at no additional
cost. |
