EMC According to EN 61000-6-2 and EN 61000-6-3 1) Enclosure rating IP67, 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 humidity 100 %, condensation permitted Resistance to shocks 30 g, 6 ms (EN 60068-2-27) Resistance to vibration 20 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.
