A Series

DC Tachometers

DC Tachometers with output signal between 1 and 10 volts/1000 rpm

A Series - DC Tachometers
from $298.00/ea

A-Series tachs are designed for use in applications requiring an output signal between 1 and 10 volts/1000 rpm. The units come in three basic configurations-instrument, industrial, and automotive.

Instrument Type
The low-cost high-performance instrument generator has a 0.120"-diameter shaft for direct drive. It is ideally suited to instrumentation applications.

Industrial Type
The industrial generator is designed for use in more rugged applications. The heavier shaft, 0.187" and special front-end ball bearing allow the unit to operate under heavier radial loads such as those found in pulley and belt drives. On many models, an enclosure on the terminal end protects the electrical connections against adverse environmental conditions.

Automotive Type
Automotive generators' SAE mounting allows for direct replacement of mechanical tachometers. The units also feature a flexible output shaft, to compensate for possible misalignment due to direct coupling.
