11-2 Needle Sensor
The NSZ Series Needle Sensor includes a Load Cell, which is used to calculate the Z-height
of the needle tip during the Calculate Master Offsets routine in FMW.
Both types of Needle Sensors use a fiber optic LED 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 the
dispensing software which uses them during the programming process and during
production runs.
The Needle Sensor allows you to 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 and between production runs, thus
minimizing operator error and eliminating wasted time spent manually adjusting the needle.

The needle sensor does not compensate for XYZ location changes in parts,
substrates, tooling or fixtures.
