Import A Grade Dku-5 Cable — Buy in Bulk from Supplier in China

The A grade DKU-5 cable from Coach Communications Industrial co.,Ltd is a serial data cable built for Nokia mobile device connectivity and legacy equipment interfacing, originating from Shenzhen, Guangdong Province. It employs a USB-A male connector on the host side and a specialised 15-pin D-sub connector on the device side, with cable length typically ranging 1.0 to 1.8 metres depending on factory configuration. The conductor uses stranded oxygen-free copper with 28 AWG signal lines and 24 AWG power lines, rated for 5V DC power delivery and full-speed USB 2.0 data transfer at 12 Mbps.

Shielding construction follows a standard triple-layer approach: aluminium-mylar foil wrap, braided tinned copper shield at 60-80% coverage, and PVC or TPE outer jacket rated for -20°C to +80°C operational temperature. The A grade designation indicates conformance to original manufacturer electrical tolerances, including differential impedance of 90 ohms ±15%, capacitance below 50 pF/metre, and crosstalk attenuation exceeding 30 dB at 1 MHz. Typical insulation materials include foamed polyethylene for data pairs and solid PVC for power conductors, with colour-coded conductors per EIA/TIA-568 wiring conventions for traceability.

Primary buyers include mobile phone repair workshops, industrial automation integrators maintaining legacy Nokia-based field devices, and telecommunications refurbishment operations across Africa, South Asia, and Latin America. The cable suits environments requiring reliable RS-232 equivalent signalling over USB-physical layer conversion, including point-of-sale terminals, medical device maintenance, and automotive diagnostic tools. Trade terms vary by order volume; buyers should confirm MOQ, Incoterms, and certificate of conformity availability directly with Coach Communications Industrial co.,Ltd, as the listing does not specify these details.

Coach Communications Industrial co.,Ltd operates from Building A, Songzi Garden, Shangtang Industrial Zone in Longhua Town, Baoan District, Shenzhen 518109, Guangdong Province, China. The supplier holds an imported tier designation on the platform, with a trust tier classified as harbor, the lowest of the verification levels available. Notably, the supplier shows a 0.00% response rate and zero average response hours, indicating no recorded engagement with buyer inquiries through the platform's messaging system. This absence of response data is a material consideration for importers evaluating communication reliability.

The company's profile focuses on cable manufacturing for communications applications, though the listing provides no independently verifiable certifications, factory audit reports, or registered capital figures. Buyers should conduct direct due diligence, including verification of business licence, export licence status, and sample evaluation, before committing to volume orders. The Shenzhen location offers proximity to component supply chains and Shenzhen port logistics, but this geographical advantage must be weighed against the limited platform-verified transaction history.
