Part Finding Sensor
Part Finding Sensors and Trigger Types
Part Finding Sensors are used differently for different trigger types.
With an Internal Trigger, a Part Finding Sensor is required. The Part
Finding Sensor tells Checker that a part is present.
With an External Trigger, a Part Finding Sensor is optional. If you do
not use a Part Finding Sensor, then the inspection sensors will run in
xed positions. If you use a Part Finding Sensor, then both the Part
Finding Sensor and the External Trigger must indicate a part before
Checker will check it.
In Free Running mode, a Part Finding Sensor is optional. If you do
not use a Part Finding Sensor, then the inspection sensors will run in
xed positions. If you use a Part Finding Sensor, then the Part Finding
Sensor must detect a part in an image before Checker will check it.
In all cases, if a Part Finding Sensor is used, then Checker uses the
part’s detected location to position the inspection sensors.
Modifying a Part Finding Sensor
You can change the location where Checker looks for the part by simply
moving the Part Finding Sensor search region.
To change what a Part Finding Sensor looks for, you must either
Create a new Part Finding Sensor in Setup mode.
Use the External Retrain feature in Setup mode or Run mode.

A Part Finding Sensor detects and locates your part in the image. You create a
Part Finding Sensor by drawing a box around a feature of part that is present
on both good and bad parts.
