Overview

The TOXU TX-A161 is a 433MHz embedded spring helical antenna developed for compact wireless communication equipment operating in the ISM frequency band. Its helical structure provides an effective electrical length while occupying minimal installation space, making it suitable for embedded electronic products with limited internal space.

Manufactured using phosphor copper, the antenna delivers stable electrical performance with 50Ω impedance and vertical polarization. It is suitable for integration into wireless communication modules, smart devices, industrial controllers, telemetry equipment, and other embedded RF systems.

As an OEM manufacturer, TOXU supports antenna customization, RF cable integration, connector selection, prototype verification, and mass production for industrial communication applications.
