The grating angle sensor is measured based on the diffraction change caused by the single-sided light source irradiated by the grating and then converted into electrical signals by photoelectric elements. The accuracy of the grating angle sensor mainly depends on the grating line density. The greater the density, the higher the accuracy. Affected by the processing level, its density cannot be increased indefinitely. Moreover, if the light is blocked due to dust, vibration, etc., the sensor signal will be affected. Now the DWQ type magnetic angle sensor produced by okplazas.com perfectly solves these problems. The principle of internal magnetic sensitivity, no contact and no wear, the principle of magnetic sensitivity and the protection of the circuit by the aluminum alloy shell make the sensor have excellent protection performance , Dust-proof, waterproof, oil-proof, anti-vibration shock up to 20000G, long-term quality assurance.
