Description
Bulletin
845T optical incremental
encoders are used to electronically
monitor the position of a rotating shaft.
Shaft motion is converted to digital
pulses which are accumulated and
evaluated by various electronic
controllers. The 845T provides code
disk resolutions of up to 3000 pulses
per revolution, and a frequency
response of up to 100kHz.
The Bulletin 845T encoder is a heavy
duty
, NEMA T
ype 4, and IP66 (IEC 529)
rated optical incremental shaft encoder
that is housed in a two inch diameter
enclosure. T
ypical applications for the
845T include machine tools, packaging
machinery
, motion controls, and
robotics. The heavy duty bearing
assembly
, rugged construction and high
shaft loading capabilities make the
845T suitable for many of today’
s harsh
industrial environments.
