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.

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.
Pomux® KH53
Product description
The POMUX KH53 non-contact linear encoder can measure absolute lengths up to 1,700 m. The encoder consists of two main components: The non-contact read head determines the absolute position using a series of measuring elements attached along the measurement path. Each measuring element consists of a number of permanent magnets. Since the distances between the magnets are unique, they can be used to develop an absolute measuring code. No reference run is required due to the absolute position being determined. The read head is passed parallel to these measuring elements at a distance of 25 mm or 55 mm. With a measuring length of up to 1,700 m the KH53 is ideal for use in cranes, in material handling and warehouse systems, and for railed vehicles. Due to the non-contact technology, this system works wear-free even in a harsh environment, so that a long lifetime is ensured.
