1)This product is a standard product and does not constitute a safety component as defined in the Machinery Directive. Calculation based on nominal load of components, average ambient temperature 40°C, frequency of use 8760 h/a. All electronic failures are considered hazardous. For more information, see document no. 8015532.
Interfaces:
Electrical interface: SSI
Interface signals: 24 Bit 1)
Sin/cos-output: Speed-proportional signal output for real-time requirements.
1)If the maximum distance between the TTK70 SSI and the magnetic tape is exceeded, bit 25 is set in the SSI data stream. The output position value is invalid! When exceeding or going below the temperature range of the sensor (< -30 °C or > +85 °C), bit 26 is set in the SSI data stream. The bits are reset as soon as the error condition no longer exists. To be able to use these additional bits, the control(ler) must be able to read in at least 26 bits of data.
Ambient data
EMC: (EN 61000-6-2), (EN 61000-6-3)
Enclosure rating: IP 67 (IEC 60529), with mating connector inserted
Working 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)
Maximum permitted field strength: < 150 kA/m (< 190 mT) (to ensure that the magnetic tape is not permanently damaged)
1)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.
