845F–SJGZ14FWY2
Description
The
Bulletin 845F is an optical
incremental encoder that provides
digital feedback corresponding to the
position of a rotating shaft. This
feedback is compatible with
Programmable Controllers, Numerical
Controllers, Motion Controllers, and
other positioning systems.
The 845F provides code disk resolution
up to 5000 pulses per revolution,
frequency response of 210 kHz, and
high immunity to electromagnetic
interference. Housed in a rugged, size
25, NEMA T
ype 4 and 13, IP66 (IEC
529), aluminum enclosure, the 845F
has a flange mount with integral
coupling for ease of installation in harsh
industrial environments.
