There are many different types of sensors available, which will work with the
MX001 control box.
Common types:
1. Sensors powered independently which provide 12V, 5V, or a 10mA DC
output signal (sourcing type output).
2. Sensors that provide switch closures or relay type outputs.
3. Low voltage, self-contained DC sensors that provide current sourcing
and/or sinking type outputs.
4. “Universal” self-contained sensors that provide a single pole, double throw
(SPDT) relay output.
In all cases, the sensor’s output signal or switch closure is expected to become
active when an object has been sensed.
The easiest sensor to use with the MX001 is a low voltage (a 10-30 volt) DC, self
contained, sensor. The industrial control box can power this type of sensor with
12V DC at 200 mA maximum and will interface to either a (PNP) current
sourcing, or (NPN) current sinking output. (Current sourced or sunk = 10 mA.) A
switch closure (relay) type output is also supported. All output types are expected
to become active when an object has been sensed.
Additionally, some sensors also provide an “alarm” output that warns the user
when sensing conditions are becoming marginal. This optional output is also
supported through the MX001. The option forces the scanner to emit a repetitive
warning tone when the sensor’s alarm output becomes active.
How the sensor interacts with the scanner depends upon which sensor options
were chosen in the HoloSet program. Refer to that manual for further details.
