AI-Powered supplier vetting
SummaryFocus Sensing and Control Technology Co., Ltd. is a China-based limited company established in 2014, with 35 employees and a Hefei, Anhui manufacturing location. It specializes in temperature sensors, thermistors, thermal fuses, humidity-related products, and selected automotive and medical sensors. The supplier reports ISO9001:2015 certification, patented and ISO-certified operations, four production lines, 6–10 quality-control staff, and stated annual outputs of 20 million NTC thermistors, 10 million thermal fuses, and 1 million temperature sensors. It offers OEM design, manufacturing, assembly, and custom-design services, and reports 90% export sales across major global regions. Evidence supports production scale, customization, international servicing, and named customer relationships. However, the provided slices do not sufficiently establish after-sales processes, financial credibility, or the depth and recency of innovation activities.
Supplier typeThe supplier is identified as a combined business and limited company based in China, with its own manufacturing location, four production lines, and product-focused activities spanning sensors, thermal components, electronics, automotive parts, and related sectors. Its stated self-operated import/export rights and 90% export sales indicate a manufacturer with international trading capability rather than only a trading intermediary.
CertificationsThe supplier explicitly states that it is ISO certified and provides an ISO9001:2015 management-system certificate. This is direct evidence of a certified quality-management system, although no additional certifications are identified in the provided slices.
R&D capabilityThe supplier states that it develops temperature sensors and thermal components, holds patents, provides professional design and custom-design services, and has three years of total R&D-engineer experience recorded. This supports some product-development capability, but the slices do not identify specific patented technologies, R&D investment, new-product outputs, or engineering-team scale sufficient for a stronger conclusion.
Production capacityProduction capability is supported by four production lines, a 1,200 m² manufacturing plant, 6–10 quality-control staff, and stated annual outputs of 20 million NTC thermistors, 10 million thermal fuses, and 1 million temperature sensors. The supplier also reports one-month lead times in both off-peak and peak seasons, indicating stated capacity for regular fulfillment, although independent verification of these figures is not provided.
Customization capabilityThe supplier explicitly offers professional design, manufacturing, and assembly, accepts OEM work based on customer designs, and provides custom-design service in the temperature and humidity field. These statements directly support the ability to handle customized and OEM requirements.
Client casesThe supplier names Schneider, Oster, Haier, Lada, and JAC as customers and states that it serves tier-one, tier-two, and tier-three OEMs across global regions. Two separate trade-record slices also associate the company with named buyers in Vietnam and Brazil, each showing one transaction; this provides customer-reference evidence, but the limited transaction counts do not establish the breadth or continuity of those relationships.
Product Q&A
Q:Does the sensor support customization?
A:
Yes, specifications such as tube material, housing size, resistance, and cable length can be customized to match your application.
Q:What is the communication interface of the DS18B20?
A:
It uses a 1-Wire interface that requires only one data line and ground for communication with a central microprocessor.
Q:What is the power supply requirement?
A:
The sensor requires a power supply between 3.0V and 5.5V.
Q:Is the sensor waterproof?
A:
Yes, it has an IP67 rating, making it dust tight and protected against temporary immersion in water.
Q:What is the response time for temperature conversion?
A:
The sensor converts temperature to a 12-bit digital word in a maximum of 750 ms.
