    • Ambient data
      EMCAccording to EN 61000-6-2 and EN 61000-6-3 1)
      Enclosure ratingIP67, with mating connector inserted (according to IEC 60529)
      Operating temperature range–30 °C ... +80 °C
      Storage temperature range–40 °C ... +85 °C, without package
      Permissible relative humidity100 %, condensation permitted
      Resistance to shocks30 g, 6 ms (EN 60068-2-27)
      Resistance to vibration20 g, 10 Hz ... 2,000 Hz (EN 60068-2-6)
      Maximum permitted ambient field strength< 3 kA/m ... 4 kA/m (3.8 mT ... 5 mT), to guarantee compliance with the quoted accuracy values 2)
      Maximum permitted field strength< 150 kA/m (< 190 mT), to ensure that the magnetic tape is not permanently damaged
      • 1) According to the listed standards, EMC is guaranteed if the motor feedback system is connected to the central grounding point of the motor controller via a cable shield and the encoder housing lays over a large area of the motor potential. If other shielding concepts are used, users must perform their own test.
      • 2) The maximum permitted external field influence is reached when the position value deviates from the original value (without external field influence) by more than 5 μm. This value is reached when, at the sensor location, a field strength of 3 kA/m to 4 kA/m (3.8 mT to 5 mT) occurs in addition to the field strength of the magnetic tape.
