SummaryChengdu Sentec Technology Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory in the electrical and electronics sector. Its stated products include multiple sensor and transmitter categories, while company descriptions highlight sensor technology development, intelligent monitoring solutions, and OEM experience. The supplier reports ISO 9001 certification, 11–20 years of R&D engineer experience, 6–10 quality-control staff, and more than 10 production lines. It has exported since 2011 and reports that 51%–70% of sales are exports, with self-operated import and export rights. An audit by BV is recorded, but the supplied audit result is “0” and the report validity period ended on 2024-11-15; the meaning of the result is not provided. Evidence remains insufficient for financial credibility, after-sales capability, overseas service coverage, detailed customization services, and verified customer cases.
Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, with a limited-company structure and electrical and electronics trade focus. This supports its ability to operate as a product supplier with manufacturing involvement, although the relative scale of trading versus manufacturing is not stated.
CertificationsThe supplier reports ISO 9001 certification, and a BV audit record is provided with a stated validity period from 2023-11-16 to 2024-11-15. However, the audit result is recorded as “0,” and no interpretation or currently valid certification evidence is supplied, so the positive certification evidence is limited to the stated ISO 9001 holding.
R&D capabilityCompany descriptions state that industry experts participate in sensor R&D and innovation, that advanced production technologies are continuously introduced and developed, and that the supplier has 11–20 years of R&D engineer experience. Specific evidence for new-product output, SDK availability, 3D design, ODM, or other measured innovation deliverables is unknown.
Production capacityThe supplier is identified as a manufacturer/factory, offers several sensor and transmitter product categories, reports more than 10 production lines, and describes industrialized and systematized production. These details provide explicit evidence of substantial production infrastructure, although capacity volume and utilization are not stated.
Customization capabilityThe supplier explicitly states it has experienced OEM services and develops sensing technology solutions for customers, which supports some customization capability. Nevertheless, the availability of ODM, OEM for popular brands, 3D software design, and new-product development services is marked unknown, so the full customization scope cannot be verified.
