You can send an inquiry or email us. We will reply within 12 hours.

Do you provide technology support?

Yes, we have over 10 years of experience. Our engineers provide suggestions to help solve any problems.

What should be noticed when using KJT sensors?

Ensure working voltage is 10-30 V DC or 90-250 AC. Check sensing distance and material. For photoelectric sensors, ensure beam availability. Ensure NPN or PNP output compatibility.

How can I get a sample?

We provide one free sample for one type of sensor (same datasheet), but you must cover the freight charge. If we do not have the sample in stock, we can produce it for you.

AI-Powered supplier vetting

SummaryThe supplier identifies itself as a factory and demonstrates several established operational capabilities. It has documented procedures and records for corrective and preventive actions, complaint handling, supplier assessment, and service capability. It reports OEM service for popular brands, ODM and multiple customization modes, in-stock capacity, 50 qualified service-capability suppliers, and peak/off-season lead times within 15 working days. Quality-related evidence includes ISO9001:2015, RoHS, and CE. However, the supplier lacks R&D audit documentation, reports zero patents, has no new products in the past year, no available SDK, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with related subcontractors. Financial records are referenced for 2022–2024, but the slices do not provide enough detail to assess financial strength. Customer-case evidence is limited to a general OEM statement.

Supplier typeThe supplier is explicitly identified as a factory, indicating direct manufacturing status rather than only a trading or service-company profile.

CertificationsThe supplier reports an ISO9001:2015 certificate and RoHS and CE product-certification capabilities. These are explicit quality and product-compliance credentials, although the slices do not provide certificate scope or validity dates.

After-Sales capabilityThe supplier has documented and followed procedures for corrective/preventive actions and customer complaints, and its R&D responsibilities include after-sales service. Service quotations and payment terms are defined, while lead time is stated as within 15 working days in both peak and off-season periods.

R&D capabilityThe supplier uses CAD and AI and offers ODM services and product design customization, but it reports zero R&D patents, no available SDK, no R&D audit documentation, and no new products during the past year. The evidence therefore shows some development tools and service capability but also explicit limitations in documented and output-based innovation.

Production capacityAs a factory, the supplier reports in-stock capacity, OEM service for popular brands, 50 qualified suppliers for service capability, written assessment procedures, and lead times within 15 working days. However, it also reports no valid manufacturing-capacity contract with related subcontractors; overall production capability is supported, but the stated contractual deficiency is material.

Customization capabilityThe supplier supports customization from samples, designs, full customization, minor customization, and flexible customization, and it provides ODM services. The R&D engineer role also includes preparing samples according to customer requirements, providing direct evidence of broad customization support.
