D & E Series
DC Tachometers with output signal between 25 and 45 volts/1000 rpm (3V/1000 rpm for E Series subminiature tach)
With rugged construction and high output voltages, D Series tach generators are ideally suited to a variety of industrial applications. The flange mounting arrangement provides a convenient assembly method, and the sturdy 0.187"-diameter shaft permits the heavier loading frequently encountered where pulleys or belt drives are employed. The output bearing is fitted with a seal to help prevent the contamination that can occur in industrial applications. With output up to 45 V/1000 rpm, D-Series generators are ideal for applications where high output voltages are required. Typically, these are slow-speed applications.
The E-Series generator is the smallest tach among those offering similar technical characteristics. Many outstanding features make it particularly suitable for use in all types of servo systems. Although the diameter is only 0.760", the E Series provides a 3 volt/1000 rpm output and linearity better than 0.1% at 3600 rpm. With driving torque of only 0.25 oz-in., and inertia of just 0.25 x 10^-4 oz-in.-sec^2, E Series gives design advantages not available with competitive units.
