H25
|
INCREMENTAL OPTICAL ENCODER
Introduction
The H25 is the flagship of the BEI Sensors product line. It was designed
from the ground up for the industrial marketplace. The H25 offers
features such as EMI shielding, 40 lb. ABEC 7 bearings, matched thermal
coefficients on critical components, and custom high efficiency optics.
The encoder meets NEMA 4 and 13 requirements when ordered with the
shaft seal. Typical applications include machine control, process control,
the wood processing industry, oil well logging, industrial weighing,
agricultural machinery, textile equipment, web process control, robotics,
and food processing.
