Precision without unnecessary recirculation.
Small mouldings, connectors, housings, terminals and contacts may be lightweight, static-sensitive, reflective or easily damaged. Bulk loading and recirculation should be controlled so the feeder does not create the very defects the inspection is intended to catch.
Features used for orientation.
Keys, pin cavities, locking latches, chamfers, colour, moulded marks and connector faces can establish pose or identity. Where the decisive feature is internal or too subtle for mechanical tooling, a camera can verify the final orientation.
Presentation to assembly.
The discharge may need a tight datum for insertion, a fixed nest for robot collection, a tube-transfer interface or controlled spacing on a conveyor. Sensors should detect the component reliably without being confused by colour or translucent material.
Format and recipe control.
Similar connectors can create expensive cross-contamination. Recipe selection, change-part confirmation, vision classification and line clearance procedures can be included where the application risk justifies them.
