The FSM-T-04A is a compact combustible gas sensor module that outputs a linear analog voltage directly proportional to gas concentration. It incorporates a TGS6812 catalytic pellistor and provides a detection range of 0 - 50 000 ppm for methane, LPG and hydrogen, with an accuracy of ±3 %LEL. The module is RoHS compliant, features conformal coating for moisture protection and includes a memory chip that stores factory calibration data. Operating temperature spans from −10 °C to +70 °C, and the unit can signal sensor wire breakage.
The sensor core uses a catalytic pellistor, a standard choice for low‑cost combustible gas detection in industrial safety equipment. Typical commercial gas sensors of this class employ a compact PCB layout and a 5 V DC supply, delivering response times under 10 seconds. The module’s compact dimensions, roughly 30×20×10 mm, match the size of typical handheld leak‑detectors. Its resistance to silicon‑based poisons and reduced sensitivity to VOCs aligns with the durability required for rugged environments such as fuel‑cell systems.
Primary applications include hydrogen leak detection in fuel‑cell installations and methane monitoring in LPG distribution networks, making it attractive to OEMs of safety controllers and system integrators. Importers should request confirmation of the calibration memory content, RoHS certification and packaging details before placing an order. The supplier lists the product under an imported tier with a harbor trust rating; MOQ, price and incoterms are not disclosed in the listing and must be negotiated directly with Week Technology Ltd.

Before placing an order for the FSM-T-04A, verify that the unit’s calibration memory is populated and request the latest RoHS compliance certificate. Ask the supplier to provide a datasheet that confirms the detection range, accuracy and operating temperature limits match the specifications listed. Confirm the packaging type, typically anti‑static bags within a bulk carton, and ensure the shipment will include a handling instruction sheet for moisture‑protected devices.
Discuss logistics early to avoid delays; the supplier has not published lead‑time, so ask for an estimated production and dispatch schedule. Clarify the preferred Incoterm - common choices are FOB Shenzhen or CIF Shanghai - for the Chinese origin, and negotiate payment terms such as a 30 % deposit with the balance payable upon presentation of the commercial invoice and inspection report. Shipping containers should be sealed and temperature‑controlled if the modules are to be stored for extended periods.
Arrange a pre‑shipment inspection by a recognised third‑party agency to verify the analog output linearity and sensor response against the stated ±3 %LEL accuracy. Request a test report that includes functional checks at the extremes of the −10 °C to +70 °C temperature range. Upon arrival, perform a visual inspection of the conformal coating and confirm that the memory chip retains the calibration data before integrating the sensors into your safety system.
