SummaryShenzhen Jutai Comm Co., Ltd. is identified as a China-based limited company with both trading-company and manufacturer/factory classifications. It offers infrared safety curtain sensors and 24G motion radar sensors, reports ISO 9001 and ISO 14001 certifications, and has factory facilities in Shenzhen. Production evidence includes more than 10 production lines, stated annual microwave motion sensor productivity of 5,000 sets, 6–10 quality-control staff, and R&D engineer experience totaling 21–30 years. The supplier has exported since 2012 and reports that 90% of sales are exports. Its company description claims complete system solutions, technology support, and after-sales service, but most detailed service, customization, R&D documentation, quality-process, and overseas-operation fields are marked unknown. Audit information identifies TÜV Rheinland, but the audit result is recorded as 0 and the report validity shown ended on 2025-12-26; the meaning of the result code is not provided.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, legally structured as a limited company and located in Shenzhen, Guangdong, China. The associated-company industry is listed as manufacturing, supporting a manufacturing connection, although the records also explicitly classify the business as a trading company.

CertificationsThe supplier reports ISO 9001 and ISO 14001 management-system certifications. A TÜV Rheinland audit is also recorded, but its result is listed as 0 without an interpretation, and the stated report validity ended on 2025-12-26, so current audit validity cannot be confirmed.
