Smart Encoder

Intuitive, Simple to Program without a PC
or Software, Shows Position/RPM on 4 digit
LED Display.

Field Programmable

A25-RI Resolver Incremental

BEI H25 encoder series has literally 215 part numbers for
different resolutions. Combine these with various output
formats (3904, 7406, 3302, 681, 689, 7272, 4469 etc.) and you
literally have more than 1000 models. Dynapar is not that
different. This presents a major challenge to the user community,
particularly plants that have equipment coming from different
machine manufacturers. Plant stock room has to carry a large
inventory and it is not uncommon to not have the one you need
in an emergency.

To solve this problem, BEI has recently introduced its Omnicoder™
series. The problem with Omnicoder is two fold:

1. You have to unplug the output connector/cable, it takes a
computer software and special cable to program it and hence
it can only be done on the bench.

2. It is too expensive.

Smart-Encoder™, solves both these problems, you can program
the counts/rev while it is installed on the machine, without any
laptop, special USB cable or software. It has a LED display to
be able to check its operation on the spot as it shows counts
and RPM. On top of all this, Smart-Encoder™ costs less than
the current industry standard fixed count encoders from BEI
and Dynapar.

As can be seen from its specification, its mechanical as well
as electrical specifications are at par, if not better, than
these other encoders.
