Sensors, robotics, vision: Angle sensor good for portable, wireless

By Control Engineering Staff June 19, 2007

Rosemont, IL —Smaller and more accurate absolute angle sensor available from GMW is among recent highlights from the Sensors Expo 2007, June 11-13 at the Stephens Convention Center. Also held that week was the Robot & Vision Show , June 12-14. The new sensor is said to be particularly suitable for portable or wireless applications because of low current draw in sleep mode.

GMW displays at the show also included magnetic sensors for magnetic field measurement, electric current measurement, linear position sensing, and angle and rotation sensing. Applications include machine condition monitoring; industrial process control; lighting, heating, cooling and power systems; wireless controls; land and marine vehicles; home appliances, and handheld products. GMW’s demonstration included magnetic sensors from Asahi Kasei EMD , Ametes, and Sentron .

The EM3241 Absolute Angle Sensor from Asahi has a very small package size of only 3.6 x 3.0 x 0.95 mm with a better than 1% linearity analog output for 0 to 360 degrees to well over 12,000 rpm, without programming or calibration requirements. A current draw of &1 uA in sleep mode makes the EM3241 particularly suitable for portable or wireless applications.
