JR SERIES
JR Series are compact
encdoers for general application
made by Astec in Japan.
|
- In general, encoderpulese
generator has longer axial
dimmention than its diameter. JR
Series has the dimensions of
dia.52.2mm x 31mm, including a
bracketa dustcover. As far as
the diamaeter is not larger than
motor case diameter, shorter
axial length is better for
saving space.
- Most suitable for avoiding
the problmes of high
temperatureoil mist.

Magnetic Encoder Kit for Robot &
Others |
|
This magnetic
encoder kit can make a gap
between MR Sensor and a
Magnetic Rotor very wide.
Depending on condtions, gap
can be from 0.3mm up to
2.0mm. No contact between a
MR-sensor and a magnetic
rotor. No bearings are
necessary. This kit is
designed by Admotec in
U.S.A. Mass production can
be made by Astec in Japan.
|
|
- For the applications which
exsiting standard encoders can
not be mounted.
- For severe environmets like
high temperature over 100 degree
C.
- For various severe
conditions and environments like
vibration, mechanical shock,
dust, water, oil, oil mist,
chemicals, etc.
- Direct mounting onto a shaft
in motor case for an encoder
included Servomotor.
- Direct mounitng onto shafts
from dia.1mm through dia.250mm.
- For the application which
requires wide air gap between a
sensor and a rotor.

Magnetic Encoder for Harsh
Environments |
 MSL115
Series are the Encoders designed for
the severe applications like
Paper-Pulp industry, Steel indutry,
Harbor Crane indstey, etc. This
series is a metric encoder made by
Dynapar distributed by Astec in
Japan.
- MSL115 Series is
bearingless, non-contac type
encoder and it can last more
than 10 years with proper way of
use.
- This Series is one of the
most rugged encoderws with
magneto-resistive sensor and a
magnetic pulser.
- MSL115 can be attached to
dia.15mm - dia.95mm motor shaft
directly without any coupling.
The other type RIM1250 can be
attached up to dia.200mm motor
shaft directly.
- This series is a
through-shaft type and it can be
mounted to the shaft between a
motor and a break or fan like
sandwiches.
- As the housing is a flat
type, it takes only 20-30mm
axial length for space saving.
- The air gap control between
the sensor and the pulser is
easy.

Magnetic Encoder vs. Optical Encoder |
| Astec has been
serving for various kinds of
industries with Magnetic Encoders
which covers the disadvantages of
optical encoders. Magetic encoders
are insensitive to severe
environments like dust, water, oil,
vibration and others. |
