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.
