What does Tonetron make?

We design and manufacture consumer AV and data-transfer cables and adapters for brands, distributors and system integrators: HDMI (including HDMI 2.1 48 Gbps and Ultra96 constructions), USB-C and USB4 up to 40 Gbps (our PF587A-0080 carries USB-IF certification, TID 6801), DisplayPort, Thunderbolt, VGA/DVI, RCA and 3.5 mm audio, MFi Lightning, plus docking stations and video adapters. The catalogue lists 130+ SKUs; most orders are OEM/ODM builds to the customer's specification, packaging and branding.

Is Tonetron a factory or a trading company?

A factory. Moulding, wire processing, assembly and testing happen in our own plant in Dalingshan, and the legal entity that signs your contract is the same one that holds the HDMI Adopter licence and the ISO 9001 certificate. We do not resell other factories' cables.

What quality system is behind each cable?

Incoming wire and connector inspection, in-process checks at every line and 100% functional testing before packing, run under the ISO 9001 system. HDMI products are built to the HDMI Adopter specification; 48 Gbps constructions carry ATC test certificates, which are published on our credentials page together with the USB4 certificate.

Is Tonetron related to Taitron Components Inc.?

No. Taitron Components Inc. (NASDAQ: TAIT) is an unrelated distributor in the United States. Our legal name appears as "Taitron" on some certificates and as "Tonetron" on others because two certification bodies transliterated the same Chinese name differently; both refer to Dongguan Taitron Electronic Limited.

How do we work with new customers?

Send a drawing, a sample or a target specification. Engineering replies with a construction proposal, test plan and quotation; samples are built on the production line, not in a lab, so what you approve is what you receive. Typical MOQ, lead time and packaging options are quoted per project. Contact: sales@tonetron.com.
