D40A/G9SX-NS

Solves Conventional Switch Issues to Provide Stable Detection
The Switch does not accurately detect the door when it is closed slowly, resulting in an error.
Issue 1
Door
closed
slowly.
An error can occur
if the door is closed
slowly with
conventional
switches.
Conventional switch
The D40A does not use reed switches and
provides stable detection with electronic switches.
Conventional Switches
Detects slow rotating operation.

If the switching timing of reed
switch contacts 1 and 2 varies
too much, the Controller
detects an error and turns OFF
the output to maintain safety.

Slow
Detects slow lateral operation.
ErrorError
It is nearly impossible to tell which door is open in a multi-door application.
Issue 2
If an error occurs...
It's impossible to tell if there is a door open or if an error has occurred.
The system cannot be started because the Controller has turned
OFF the output even though all doors appear to be closed.
All doors must be opened and closed before operation can be started.
With the D40A...
Solution 2
The auxiliary outputs can be used to easily indicate which door is
open.
And with two-color indicators, mounting adjustments are also easy.
The D40A is the first Non-contact Door Switch to combine 2-color
indicators, auxiliary outputs, and 30-switch connection capacity,
allowing you to create a better safety environment.
Various cable lengths and complex wiring are required for multiple doors.
Issue 3
Solution 3
The model with a connector allows you to select the cable lengths that are connected and purchase the
cables of required lengths. Switches can be integrated into a single Switch with a connector.
Downtime can be reduced by replacing the cable and switch partially at maintenance time.
