BEI Sensors H20 Express Encoder - Manual

The H20 is an extremely rugged encoder designed to economically
fill the resolution range up to 4096 cycles per turn. This compact
unit features a shock resistant disc, heavy duty bearings, and EMI
shielding. The H20 conforms to NEMA 4 and 13 requirements. The
H20 is also available in a hub shaft style with a flexmount (inset) for
easy mounting directly to small motors. Typical applications of the
H20 include machine control, process control, agricultural machin-
ery, textile equipment, robotics, food processing, and metering.
