Import Gd-F28 Fixed/Roling Code Transmitter — Buy in Bulk from Supplier in China

The GD-F28 fixed/roling code transmitter is offered by GD Techway International Electronic Co., Ltd, based in Shenzhen, Guangdong, China. It employs both fixed and rolling code technology to prevent unauthorised access and includes a built‑in voice transmission module for audible alerts. The device provides an extended wireless range that can be suited to a variety of installation layouts, and its user‑friendly interface allows simple operation for installers and end users alike. Compatibility with a broad set of smart‑home and security platforms makes it a versatile choice for both residential and commercial projects.

In the wider market, wireless security transmitters of this class typically operate around the 315 MHz ISM band and are powered by a 3 V coin‑cell battery, delivering several months of service between replacements. Standard dimensions for comparable units are roughly 50 × 30 × 15 mm, allowing discreet mounting in door frames or window panels. They are engineered to function reliably from - 20 °C to 60 °C and often use on‑off keying (OOK) modulation to maintain low power consumption. GD Techway’s model follows these industry norms while adding voice feedback, a feature not always present in similar transmitters.

The transmitter is suited to smart‑home automation, electronic access control for doors, windows and curtains, as well as industrial security installations. Importers should note the supplier advertises flexible minimum order quantities and holds ISO certification, confirming adherence to recognised quality standards. Packaging is supplied in export‑ready cartons and the supplier mentions FOB and CIF shipping options, though exact lead times and incoterms should be verified directly with GD Techway before placing an order.
