FAQ

Q: Are your automotive connectors compatible with major Tier 1 OEM terminal footprints?

A: Yes. Our connectors are engineered to standard industrial dimensions, offering drop-in interchangeability with major connector series including Molex Mini50, JST SH/NH, and Yeonho PHB series.

Q: What secondary locking mechanisms are built into these housings to prevent terminal backing out?

A: Our housings feature built-in TPA (Terminal Position Assurance) or ISL (Independent Secondary Lock) structures. Once terminals are inserted, the secondary lock snaps into position, physically blocking terminal retraction under heavy harness pulling or vibration.

Q: What certifications do your manufacturing facilities hold?

A: Manufacturing facilities operate under IATF 16949 and ISO 9001 quality management systems. All materials comply with RoHS 2.0 and REACH environmental directives.

Q: Can you provide custom wire harness pigtail assemblies using these connectors?

A: Yes. We offer complete OEM pigtail wire harness manufacturing, including custom wire cut lengths, terminal automated crimping, stripping, heat-shrink tubing, and custom pinouts.

Q: What is the minimum order quantity (MOQ) for standard stock vs. custom connectors?

A: Standard stock items have an MOQ starting at 1 reel or 1,000 pieces per bag. Custom molded housings or non-standard terminal plating options require an MOQ of 10,000 to 50,000 pieces depending on tooling requirements.

Q: What testing reports are supplied with pre-production samples?

A: Pre-production sample shipments include initial sample inspection reports (ISIR), dimensional measurement sheets, contact resistance test data, terminal pull-out force reports, and material compliance certificates.
