Specification No. 02002-001 Rev.08-13
These commodities, technology or software if exported from the United States must be in accordance with the Bureau of Industry, and Security, Export Administration regulations. Diversion contrary to U.S law is prohibited.
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.
