TPMS manufacturer in China, factory direct

What you can verify before placing an order

A buyer looking for a Chinese TPMS manufacturer is usually trying to answer one question: is this a factory or a trader? These are the things you can ask us for, and check.

• Registered entity and address. Shenzhen Guangzhan Electronics Co., Ltd., registered in Nanshan District, Shenzhen. Company registration documents available under NDA.
• What we actually make. The sensor, the receiver and the gateway are our own designs. We do not resell another factory's TPMS under our name.
• Our own test line. Pressure calibration (100% of units), immersion, RF distance, RF centre frequency, full wheel-count simulation, burn-in, CAN/serial protocol verification, battery and power, appearance and dimension. Ask for the process list and we will send it.
• Marking. Laser marking for model, batch and serial identity — per-unit traceability if your programme needs it.

What we supply, and in what form

Two product families, kept strictly separate:

• Industrial line at 433.92 MHz — external and internal sensors, receivers with CAN 2.0B / J1939 / RS485 / RS232 / Modbus RTU / PROFINET / UART, repeaters, cab displays, and a 4G CAT.1 + GPS gateway. Up to 256 wheel positions per receiver.
• BLE line at 2.4 GHz — Bluetooth 5.1 sensors that pair directly to a phone app or head unit, with no receiver on the vehicle.

Both are supplied as components: your brand on the housing, the packaging and the app.

Certification status — stated plainly

We do not hold a finished-product CE certificate today. What we can say is: CE in progress, components are RoHS/REACH compliant with supplier declarations available on request, and our BLE module carries its own BQB / FCC / CE / IC / SRRC approvals, which a modular-approval route can reference in your own certification. We will not claim a certificate we do not hold — if a supplier tells you otherwise without a certificate number, ask for the number.

How an order usually starts

Tell us the vehicle, the wheel count, where the data has to go and the label language. We answer in writing with the configuration, the interface and the documentation you would receive. A small first order to test the channel is normal.
