H25 Incremental Optical Encoder 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. Special Models of the H25 Incremental Encoder are available with one or more of the following certifications. Consult factory for details.

Mounting is usually done either using the D-style square flange mount, E- or G-style servo mounts, or one of the standard face mounts, F1 for example. Consult factory for additional face mount options. 2.The shaft seal is recommended in virtually all installations. The most common excep- tions are applications requiring a very low starting torque or those requiring operation at Tables both high temperature and high speed. 3. Non-standard index widths and multiple indices are available by special order. Consult factory. Table 1: Incremental Output Terminations 4.
