AI-Powered supplier vetting

SummaryFocusens is presented as an ISO-certified, patented manufacturer specializing in temperature sensors and thermal components, with more than 15 years of field experience. It reports product development, ODM, OEM, and multiple customization methods, plus documented quality, complaint-handling, corrective-action, supplier-assessment, and finished-product inspection procedures. Export activity is substantial, with 90% of total sales from exports and 11 years of exporting experience. Production information confirms several equipment categories and stated capacity for level sensors and transmitters, but capacity details for other listed products are incomplete. The supplier has inventory capability and defined quotation, payment, and lead-time terms, but reports no overseas agents, branches, warehouse, showroom, or SDK, and no valid manufacturing-capacity contract with related subcontractors. Financial evidence is limited to year labels rather than performance figures, so credibility cannot be fully assessed.

Supplier typeFocusens identifies itself as a manufacturer developing, producing, and servicing temperature sensors and thermal components. It also provides OEM/ODM services, has patented and ISO-certified status, and reports more than 15 years of field experience and 11 years of exporting.

CertificationsThe supplier states that it is ISO certified and holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, with CE product certification capability. The provided information does not specify certificate validity dates or scopes.

R&D capabilityFocusens reports patents, product development activity during the past year, R&D capability, ODM services, and customization from designs or samples. It also reports no available SDK, which limits evidence of software or platform-based development capability.

Production capacityThe supplier lists equipment including dry ovens, terminal and channelling machines, laser marking, and shrinking-baking machines, and states that level sensors and transmitters have annual productivity of 500,000 pieces. It also reports inventory capability and lead times of one month in peak season and within 15 working days off-season, but provides no quantified capacity for temperature sensors or NTC thermistors and has no valid manufacturing-capacity contract with related subcontractors.

Customization capabilityBoth slices explicitly report customization from designs, full customization, and customization from samples. The supplier also states that it provides custom design services in the temperature-and-humidity field and offers ODM services.

Product Q&A

Q:What is a PTC thermistor motor protection sensor?

It is a positive temperature coefficient thermistor used to monitor the temperature of motor windings, power devices or machines. Its resistance increases significantly around the specified rated control temperature TK.

Q:What does TK mean?

TK is the Rated Control Temperature. It is the key temperature around which the PTC resistance changes significantly and the protection circuit can detect an over-temperature condition.

Q:Can I use three PTC thermistors for a three-phase motor?

The supplied product supports a triple thermistor configuration. This can be used where three sensing points are required. The final installation should be determined according to the motor design.

Q:Can multiple PTC thermistors be connected in series?

Yes. The supplied product information states that PTC thermistor beads with different rated response temperatures can be connected in series.

Q:What configurations are available?

Single / Double / Triple / Sextuple thermistor configurations.
