The little electronics corporation of Austria released EasyPoint control rod module suitable for the walkie communicating device a few days ago.

EasyPoint include one mechanical assembly, integration navigate knob, one magnet and non-contact type sensory IC AS5011. Its simple structure and adopting non-contact type sensory technical AS5011, mean this module can offer very high mechanical reliability. EasyPoint control rod module supports the genuine 360 deg motion detection, and have " choose " The function, suitable for many kinds of physical dimensions, the module is very low to 1.8mm in height.

The core of EasyPoint control rod module is a a little electronic magnetic Coder IC AS5011 of Austria, can measure and move to the knob in the central position, and lose and offer the place information through I2C. AS5011 has user's available power saving modes, adopt ultrathin QFN to capsulate (5x5mm, the height is 0.55mm) .

Austrian microelectronics industry and medical director Matjaz Novak of Division's market show: "Utilizing EasyPoint control rod module technology, we can offer the high reliability module suitable for various walkie communicating device. Our solution also has high usability except having high reliability. Users can move the cursor to the arbitrary angle, change the moving speed of cursors, or and optional item pulls it on the screen. "

Austrian little electronics corporation released the linear Hall transducer IC AS5304 and AS5306 of two sections of high performance a few days ago, have expanded its magnetic quantity sensor product series.

AS5304 and AS5306 possess the new characteristic of the magnetic Coder series of Austrian microelectronics, the application demand of satisfiable linearity and abaxial motion detection. These two devices needn't carry on the disposition or normalize through the main control unit during power up or operation!, can offer the convenient solution for the fact that motion control is employed. The new linear magnetic Coder IC is suitable for application of many kinds of motion detections such as medical treatment, industry or consumption products.

Austrian microelectronics industry and medical director Matjaz Novak of Division's market show: " Adopt the kinetic control system of the traditional optical encoder, the serious influence that it measures the characteristic and the reliability will receive pollutants such as dirt, dust,etc.. And AS5304 and AS5306 use the magnetism to measure mechanism, can avoid these pollutant effects and and then promote the applied reliability of motion control notably. "

Similar to optical sensor, AS5304 and AS5306 can offer the increment type A/B orthogonal outcoming signal, every magnetic pole is right to correspond to 160 steps, and each magnetic pole, to outputting an index pulse. Consulting the known home position after power up, artificers can also combine index pulse and orthogonal outcoming signal and develop the application of the absolute location of tracing. AS5304 and AS5306 can offer 25& mu respectively; M and 15& mu; Definition of m.

Can adopt the magnetic grating of the straight line on one hand, make it displace laterally from left to Right deviation or from right to left on IC, in order to realize the application of canonial linear alignment; In addition, AS5304 and AS5306 Coder IC can also be adopted and installed in the axis of rotation peripheral annular magnet, realize and rotate abaxial application. As to making the magnet to should use to be unable to put directly on the termination of axis of rotation because the mechanical condition is limited, it is very suitable to rotate and leave the code solution of the shaft type.
