FrSky Opto RPM ADV Sensor – Optical RPM Telemetry, FBUS & Smart Port (04100491)

PRODUCT VIDEO

DESCRIPTION

The FrSky Opto RPM ADV sensor measures rotational speed using a high-speed optical detection system, making it ideal for clean, high-RPM applications where non-contact sensing is preferred.

Part of the ADV sensor series, it supports both FBUS and Smart Port (S.Port) for seamless integration into modern FrSky telemetry setups.

Designed for extreme RPM ranges, this sensor is capable of measuring up to 600,000 RPM, making it a strong fit for EDFs, turbines, and high-speed electric systems.

OPTICAL RPM SENSING
