Magnetic Rotary Encoder Astec Co., Ltd., Encoder

Flat Magnetic Rotary Encoder made in Japan

Astec JR Series

JR Series are compact encdoers for severe environmets made by Astec in Japan.

JR205: Standard

In general, encoder or pulese generator has longer axial dimmention than its diameter. JR Series has the dimensions of dia.52.2mm x 31mm, including a bracket and a dustcover. As far as the diamaeter is not larger than motor case diameter, shorter axial length is better for saving space.

JR Series stands against severe environments like high temperature, high humidity, vibrations, oil mist, dusts, etc.

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.

カスタム仕様 磁気式ロータリーエンコーダー キット

  1. For the applications which exsiting standard encoders can not be mounted.
  2. For severe environmets like high temperature over 100 degree C.
  3. For various severe conditions and environments like vibration, mechanical shock, dust, water, oil, oil mist, chemicals, etc.
  4. Direct mounting onto a shaft in motor case for an encoder included Servomotor.
  5. Direct mounitng onto shafts from dia.1mm through dia.250mm.
  6. For the application which requires wide air gap between a sensor and a rotor.

Magnetic Encoder for Harsh Environments

IP65 磁気式 ロータリーエンコーダー

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.

  1. MSL115 Series is bearingless, non-contac type encoder and it can last more than 10 years with proper way of use.
  2. This Series is one of the most rugged encoderws with magneto-resistive sensor and a magnetic pulser.
  3. 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.
  4. 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.
  5. As the housing is a flat type, it takes only 20-30mm axial length for space saving.
  6. 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.
