Import Hall Current Sensors — Buy in Bulk from Supplier in China

Rongtech Industry (Shanghai) Inc. manufactures Hall current sensors that detect magnetic fields generated by electric current. The devices cover a measuring range from microamperes up to several hundred amperes. They deliver accuracy that remains within typical ±0.5 % of full scale with minimal temperature drift. The sensors are offered with both analog voltage output and digital communication options.

The Hall effect principle used provides a non‑contact method of current measurement, reducing wear compared with shunt‑type sensors. Typical supply voltage for the modules is 5 V DC and they operate reliably between - 40 °C and 125 °C. Standard Hall sensitivity of about 10 mV per amp and response times under 1 µs are common in this class of sensor. The compact footprint, often around 10 mm × 10 mm × 5 mm, eases integration into automotive, industrial machinery and renewable‑energy equipment.

Buyers such as vehicle manufacturers, factory automation firms and energy‑system integrators select these sensors for real‑time monitoring and safety control. Rongtech states that ISO and CE certifications are in place and that packaging is designed for transit protection. Order quantities are flexible, and shipping terms can be arranged as FOB or CIF, but exact MOQ and lead time should be confirmed directly with the supplier.

Rongtech Industry (Shanghai) Inc. is based at No.912 Humin Road, Shanghai 200235, China. The company is listed as an imported supplier and carries a harbor trust tier, indicating a moderate level of verification. Its response metrics show a 0 % response rate and no recorded average response time, suggesting that communication may be delayed. These signals help buyers assess the reliability of the supplier.

The listing highlights flexible minimum order quantities, ISO and CE certifications, and protective packaging, but does not disclose exact MOQ, lead time or pricing. Rongtech positions the Hall current sensors for sectors such as automotive, industrial automation and renewable energy, aligning with the product description. Prospective buyers should request detailed quotation and confirm any additional compliance documentation before proceeding.
