When the dispense head is lowered toward the workpiece to begin dispensing, a stainless steel touch probe extends and gently contacts the work surface. The probe triggers an optical sensor that causes the dispense head to decelerate its downward (Z-axis) movement, bringing the dispensing valve's needle to its programmed dispensing height above the workpiece. After performing the height sense, the probe retracts and the dispensing cycle begins.
Users can operate the Slim Line Height Sensor in different retract modes, using Asymtek's Fluidmove® for Windows XP® software. The probe can be reconfigured to retract after each height sense, or to sense at every dispense point.
The probe applies only 7 grams of force as it contacts the substrate. The low force minimizes substrate flexure and vibration, and avoids damage to delicate substrates. Other types of probes may be used when appropriate. The probe is easy to rotate out of the way for needle tip changes.
