Figure 12-2 NS Series Needle Sensor
The NSZ Series Needle Sensor includes a Tactile Sensor, which is used to calculate the Z-
height of the needle tip during the Valve Offsets routine in Fluidmove.
Both types of Needle Sensors use a fiber optic LED and an infrared sensor to locate and
record the XYZ location of the needle. The Needle Sensor is also used to determine the
XYZ location of the Height Sensor Probe in relation to the needle. These locations are sent
to dispensing software which uses them during the programming process and during
production runs.
The Needle Sensor allows you change needles and continue production without
reprogramming the dispensing system. It can automatically compensate for XYZ changes
in needle location due to a needle change or bent needle between production runs, thus
minimizing operator error and eliminating wasted time spent manually adjusting the
needle.
? NOTE The Needle Sensor does not compensate for XYZ location
changes in parts, substrates, tooling or fixtures.
