The Trumeter TR3 Tru-Trac series is an all-in-one heavy-duty encoder and spring-loaded measuring wheel designed to be a versatile solution for tracking velocity, position or distance over a wide variety of surfaces in almost any industrial application. This model comes in a single-wheel format with a 12"-circumference urethane wheel, 500 cycles per revolution, quadrature a channel and b leads, a pull-up resistor output, and a 36" connector cable.
