Milltronics Millpulse 600
■ Overview
■ Design
Mounting
The Millpulse 600 should be mounted in an area classified as
non-hazardous, that is suitable to the enclosure rating and
materials and is within the temperature range specified. The cap
should be accessible to allow for wiring and viewing of the status
display LED.
When mounting the Millpulse onto a vibration-free structure, use
the supplied mounting flange to ensure that there is no danger
of the target damaging the unit.
Where possible, mount the probe so the cable inlet is pointing
downward to avoid accumulation of condensation in the casing.
Where wiring must be run in conduit, use a flexible conduit for
easier removal or adjustment of the probe. Keep the Millpulse
away from high voltage or current runs, contactors and
the variable frequency drives.
Do not connect the Millpulse 600 directly to supply.
Milltronics Millpulse 600 is a heavy-duty 2-wire motion sensor
that provides solid state switch output to PLCs between 18 to
135 V AC or DC.
■ Benefits
•

•
Up to 100 mm (4 inch) gap between Millpulse and targets
Two-wire unit
PLC compatible
Rugged, low maintenance suitable for tough environments
Visual indication of target triggered pulses
■ Application
Millpulse supplies cost-effective equipment protection even in
the harshest conditions.
This rugged unit is impervious to dust, dirt, build-up, and
moisture, and is ideal for such primary industries as mining,
aggregate, and cement plants. Operating where other systems
are prone to failure, the non-contacting design eliminates the
need for lubricating, cleaning, and part replacement. It will
reduce downtime and clean-up expenses associated with
conveying equipment failure. Its pulse output can be used to
minimize spillage, prevent damage, detect fire caused by belt
slippage at the head pulley, and warn of other conveyor
malfunction.

Interconnection
If the manufacturer of your PLC does not state that it is
compatible with CENELEC 50040/36/37/38 electrical standards,
then ensure that the switching current of the PLC input is above
the residual current of the MillPulse. If your PLC does not meet
the requirements, a resistor across the PLC inputs can be used
to increase the switching current.
