Elinco FB-186 Tach Generator DC Motor Tachometer is a compact tachometer component designed for use with DC motors to monitor rotational speed and provide a corresponding electrical signal. This model, FB-186, is specified at 4.4 V and 1000 RPM. As a tach generator, it supports speed sensing and feedback in motor control or instrumentation setups that require a low-voltage tach output. Use cases include hobby robotics and small drive systems where a reliable speed reference from a DC motor is needed.
