Tachometers are used to measure the velocity of a rotating object.

 Tachometer generators and tachogenerators are small AC or DC generators that output a voltage in proportion to the rotational speed of a shaft.

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation.

Engines and components are used to convert energy into mechanical force and motion for automotive and industrial applications.

Magnetic speed sensors rely on a magnet as the sensing element or sensed target to capture rotational or linear speed.

DC motors are most commonly used in variable speed and torque applications.

Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
