Customer Challenges / Request
While our customer could inspect wiring of harnesses, they had no reliable method to detect half-inserted connector pins—a common defect that can lead to poor connections.
Our Solution
Seiken proposed a custom test fixture designed to address both concerns in one operation:
- Detect half-inserted pins.
- Perform a standard pin assignment check—all within the same fixture.
This dual-function fixture simplified the workflow.
Results & Benefits
Previously, half-inserted pins could only be checked manually by sight and touch. With the new fixture, inspection time was dramatically reduced and visual and tactile inspection was replaced with consistent testing.
Application
This solution is ideal for harness assembly lines where both wiring correctness and half-inserted pins need to be inspected. By integrating these inspections into a single fixture, manufacturers can ensure higher product quality with less labor.
