Magnetic Encoders handle harsh environments.

Press Release Summary:

Series EK6210 encoders measure motion in environments with shock and vibration, dust, oil, moisture, and salt spray. Kits include encoder wheel up to 10 in. dia, magnetoresistive sensor, and line-driver outputs for 2 incremental channels in quadrature. Series EK6310 provides 3-channel versions. Encoders have resolution up to 4500 CPR. Applications include control of ac motors, engine testing, machine tool spindles, and sensing and positioning of large shafts.

Original Press Release:

Large Bore Magnetic Encoders For High Performance in Harsh Environments

Lebanon, N.H. April 15, 2002 Admotec Inc., a leader in motion and positioning sensing, has developed a new line of magnetic kit encoders, the Series EK6210, for large shaft, high performance applications in harsh environments.

The new magnetic encoder kits consist of a custom-configured magnetic encoder wheel and a matched magneto resistive sensor with line-driver outputs for two incremental channels in quadrature. Three-channel versions (with marker) are available as Series EK6310.

The new encoder kits are available with wheel diameters from 210 (8.25 in) to 250 (10 in.) mm and inside diameters sized to fit the application. Customized units are also available. The encoder provides resolution up to 4500 CPR, performance not previously available and 10 times the resolution of comparable gear-tooth sensors in the same application.

The new encoder kits are installed quickly and easily without the delicate alignment associated with optical encoders. The rugged, injection-molded encoder wheel and hybrid IC sensor provide reliable operation in harsh environments with high shock and vibration, dust, oil, moisture and salt spray.

Applications requiring these performance characteristics include vector control of AC motors, engine testing, machine tool spindles, and the sensing and positioning of large shafts in industrial equipment.

Admotec also manufactures other high performance motion and position sensing devices including the Rotasyn(TM) solid-rotor resolver for high speed applications, the EK500 Series for harsh environments and the FM700 Series flat magnetic encoders. Technical data is available at Admotec is headquartered in Lebanon, N.H. and has offices in Zurich, Switzerland, serving the European marketplace.
