Integrated encoder offers more functionalityThe new IEH2-4096 integrated encoder from EMS offers higher resolution, an expanded operating temperature range and further-improved speed control, especially in the low speed range. The new model lengthens the motor by just 1.4 mm and can be combined with numerous precious-metal commutated DC-micromotors. Because these are used in very small machines and assemblies, size plays a decisive role.
With the IEH2-4096, the previous components - sensor and circuit - are replaced by one single-chip Hall module. This newly developed circuit board is more thermally robust than the previously used magnetoresistive sensors and integrated circuits. As a result, the operating temperature range is expanded considerably to -40 to +100°C. At 4096 pulses, the encoder has a resolution four times higher than the previous model, which leads to improved control dynamics. The model also offers improved speed control, particularly at low speeds. However the IEH2-4096 remains mechanically compatible with the previous models.
The IEH2-4096 integrated encoder can be used in application areas such as in measurement devices, for valve adjustment, in camera technology, and in precision optics, for example for mirror positioning or lens or filter adjustment. These applications are characterised by sophisticated engineering in which the individual components cannot occupy much space. The IEH2-4096 integrated encoder satisfies these requirements.
It can be combined standard with precious-metal commutated motors with diameters from 15 to 22mm and lengthens them by just 1.4mm. Encoders with a separate attachment housing require several times more installation space.
