FAQs
How to quickly and accurately select the right sensor?
Answer: Start by defining the physical parameters, their range, and the environment. For example, measure 0-100°C with a 4-20mA output, or detect a metal target at 10cm in harsh conditions. Consider power, mounting, response time, and environment (temperature, vibration, EMI). Our engineers provide 1:1 support and selection guides. With 50+ sensor categories (force/load, temp, pressure, level, image, etc.), we match the best model to your specifications using datasheets and application examples.
How do you guarantee sensor quality and avoid counterfeit and inferior products?
Answer: Sensor quality is our top priority-quality issues or counterfeits force OEMs to switch suppliers. We have ISO9001:2015-certified processes and 100% incoming inspection. All parts are factory-original (no gray market), each with a serial-numbered QC certificate. Our defect rate is <0.1%. Every sensor ships with CE/RoHS marks and meets declared specs. Customers receive official test reports on demand.
What is the minimum order quantity (MOQ) and lead time?
Answer: We accept single-piece (MOQ=1) orders, including samples. Stock items ship in 1-3 days; custom or large orders typically ship in 7-15 days. We run 24/7 production (1000+pcs/day) and maintain >60-day buffer stock. Strong capacity and multiple lines ensure >99% on-time delivery. For urgent needs, we offer expedited service (air freight within 48h).
What are the competitive advantages of your prices?
Answer: As a factory supplier, our base prices are typically 20-30% below brand-name vendors. We offer tiered volume discounts (e.g. ≥100pcs: -5%, ≥500pcs: -10%). Combined with seasonal promotions (often an extra -10-20%), this delivers major savings. We absorb certification costs (ISO/CE) in-house, so no extra fees. Our large volumes and lean operations translate to stable, low prices without compromising quality.
What certifications and qualifications do your sensors have?
Answer: All our sensors come with CE and RoHS certification by default. Critical models (e.g. safety or medical) also hold UL/CSA/ATEX or FCC as needed. Our plants are ISO9001:2015 certified. We provide official certificates and batch reports upon request. (Indeed, customers note that CE marking gives confidence for compliance.) Every shipment includes a compliance pack (e.g. CE, RoHS declarations).
What about the after-sales service and warranty period?
Answer: Standard warranty is 24 months for all sensors (extendable to 36 months for large OEM projects), with 24*7 technical support. We know poor after-sales can downgrade a supplier, so we aim >95% satisfaction. Defective units are repaired or replaced within 48h. We also offer free recalibration and firmware updates. In summary: two-year coverage, 7*24 engineer support, and rapid RMA turnaround ensure peace of mind (peace of mind) after purchase.
Do you provide OEM/ODM customization services?
Answer: Yes. Our in-house R&D team (20+ engineers) has delivered 1000+ custom sensor projects. We can tailor range, output (analog/digital), housing, and firmware to your spec. Prototyping lead time is ~4-6 weeks; production MOQ can be as low as 500pcs (often lower for standard variants). We handle turnkey development: you get custom labels, packaging and documentation. Whether custom calibrations or unique form-factors, we collaborate closely on each OEM/ODM design.
What advantages do you have compared with other suppliers?
Answer: We are an integrated manufacturer controlling chip design, circuit assembly and quality testing end-to-end. This cuts costs and defect rates. We hold 50+ patents and stock 5000+ ready SKUs across all listed categories. Global clients in 100+ countries rely on our ~10-day delivery and <2h support response. Industry practice favors suppliers with strong production resources; our 24/7 facilities and backup lines embody that. In short: vertical integration, extensive inventory, rapid service
