FAQ

Product RFQ questions

Common questions to confirm before requesting samples, drawings or quotation.

Can I request samples and technical drawings?

Yes. Send the AC-WH-028S application, expected quantity and any reference drawing or sample photo. Sample, datasheet, 2D drawing and controlled 3D file availability will be confirmed for the exact model before release.

Can this connector be customized for an OEM project?

Housing color, keying, wire length, terminal, seal and packaging options can be reviewed after the mating interface, electrical load, environment and annual demand are confirmed.

How are the housing, terminal and seal matched?

Matching is reviewed as a complete connection system. Provide the mating part, wire range, insulation diameter and target IP rating so the 2.8mm sealed crimp terminal terminal and seal combination can be checked.
