10-12 Height Sensor
Operation
Height Sensor operation is controlled by Setup selections in FmNT. You can also insert
more height sense commands directly into dispensing programs.
When not measuring height, the Height Sensor probe remains retracted, preventing it from
interfering with the dispensing process.
Theory of Operation
The Height Sensor uses a stainless steel probe to contact the dispensing surface. The probe
tip is machined to minimize surface contact. Approximately 5 grams (0.18 oz) of contact
force is exerted during a substrate height measurement. The low force eliminates substrate
flex and vibration caused by probing. It also reduces placement inaccuracy and damage to
delicate substrates.
Using the height sensor’s substrate height information, the dispensing system maintains a
constant dispensing height during production runs.
