01Define the required part
Use the correct assembly reference and variant.
Check that a required component is visible
A supported presence check can flag an expected component that is not visible in the inspection view. Validate presentation and the applicable assembly revision so a hidden or differently positioned part is not mistaken for a missing one.
Confirm detector support, camera suitability and the proposed event workflow before deployment.

How It Works
Review absence against the correct assembly reference Help operators investigate an apparently incomplete assembly before the next step.
01
02Control the inspection view
Make the relevant location visible at the chosen step.
03Review the candidate absence
Check occlusion, presentation and model output.
04Inspect the assembly
An operator verifies the part before approving the next step.

| Dimension |  Missing-component detection |  Incorrect-component detection |
|---|---|---|
| Observation |  Presence or apparent absence of a specified component in a defined view. | Visible component features compared with an approved reference. |
| Event criteria | The expected visible component is not found under validated criteria. | A supported comparison indicates a candidate type mismatch. |
| Monitoring setup | Specify the component, assembly variant and inspection position. | Define valid variants, distinguishing features and reference revisions. |
| What it cannot establish | Not visible does not necessarily mean absent; hidden parts and electrical function remain unverified. | Visually identical parts may differ internally; appearance does not establish material or electrical specification. |
| Practical outcome | Help operators investigate an apparently incomplete assembly before the next step. | Help quality teams investigate visible part mismatches before further assembly. |

What Can You Do With Missing-component detection?
01 / 04 · MISSING-COMPONENT DETECTION
Electronics
A connector may be omitted before enclosure.
Example event: The expected connector is not visible.
Operator response: Inspect the assembly against the work instruction.
Practical value: Focus review before closure.

02 / 04 · MISSING-COMPONENT DETECTION
Automotive components
Small retaining clips are difficult to check quickly.
Example event: A required clip location appears empty.
Operator response: Verify the location and part variant.
Practical value: Support a specific completeness check.

03 / 04 · MISSING-COMPONENT DETECTION
Consumer products
A visible accessory must be present before packing.
Example event: The supported check does not find it.
Operator response: Confirm the product specification and correct the omission if verified.
Practical value: Provide an inspection cue before packing.

04 / 04 · MISSING-COMPONENT DETECTION
Deployment review
Use a stable close view of the required component location.
Visibility: Occlusion, glare and similar background features can hide a part.
Configuration: Validate presence detection for every supported assembly variant.
Privacy: Frame the assembly rather than unrelated worker activity.
Human review: Physically confirm an apparent absence before rejection or rework.

Frequently asked questions
Missing-component detection, Explained.
Check whether a specified visible component is present at an inspection point.
Can it detect hidden components?
Not with a normal external view; inspect before enclosure or use another appropriate method.
Does presence prove correct installation?
No. Seating, torque and electrical connection require separate checks.
What if the product variant omits the part?
The inspection must use the correct controlled variant reference.
Can it reject the item automatically?
Any reject integration and decision policy must be separately validated.

What are you trying
to achieve?
