Description
The 44N provides an economical, noncontact, solution to zero
pressure accumulation conveyor systems by combining
built-in zone control with a photoelectric sensor. This simple
approach replaces the conventional mechanical switch
sensing device, central PLC, and large quantities of
interconnecting wiring.
The use of a photoelectric sensor eliminates the need for
minimum weight restrictions required by mechanically
actuated switches. The polarized retroreflective sensing mode
ensures reliable detection of even shiny packages over a
4.8
m (16 ft) range.
The 44N comes complete with micro QD connections to both
an upstream and downstream 44N along with a variety of
connection options for common pneumatic valves. Power for
the 44N and the valve is distributed through these
connections.
The zone logic of the 44N ensures that product being loaded
on the conveyor will be separated into zone length gaps thus
providing zero pressure accumulation throughout the
conveyor system. Once product has accumulated, it may be
released individually (singulate) or simultaneously as a train
(slug). This release is activated through an external contact
closure.
