The TURCK BL ident System
D101583 0207 BL ident1 – 6
Size
TURCK supplies the data carriers with diameters of 16, 20, 30 and
50 mm.
The read-write units are available in different housing styles ranging
from cylindrical M18 and M30, to rectangular CK40 and Q80 and
ring-shaped S32XL.
Memory capacity
The memory capacity on the data storage device is 64 Bytes or
128 Bytes with an EEPROM memory and 2KBytes with an FRAM
memory. New data carriers are in the design stage.
FRAM: (Ferroelectric Random Access Memory), non-volatile, high
service life based on the higher number of write-read operations
(10
10
up to 10
11
)
EEPROM: (Electrically Erasable Programmable Read Only Memory),
non-volatile
Write time/read time (air interface only)
The write and read times depend for all data carriers on the number
of bytes which are to be transferred. On FRAM data carriers the read
and write time are almost identical and are between 0.7 and 3.4 ms/
byte. On EEPROM data carriers the read time is between 0.7 and 6
ms/byte and the write time is between 3.3 and 7.9 ms/byte.
The write-read distances depend on the corresponding combination
of data carrier and read-write head, and can be between 0 and
200 mm. With the BL ident configurator the application variables
speed, range and data quantity can be varied and the optimum
combination can be selected for the respective application. The
configurator is available online at http://www.turck.com/ (also see
page 1 - 8).
