tv = 150 ns measured with 1 m cable
tm = 31 µs independent of the clock
frequency
t < tm
Fig. 4-2: Pulse diagram, example with 24 bit coding
Null point
Position of magnet:
1a, 1b) out of the measurement range
2) within the measurement range
3) magnet not present
"Out of Range" Bit 2 will be set
21
after the occurence of the event.

The time tm starts with the falling
edge of the last clock impulse (bit 24
or bit 25 depending on the version).
Value of the output data 2
1a) 0
1b) max. at end point + 10 mm
2) proportional to distance
3) 0
Technical data are valid within the
measurement range only, i.e. between
null and end point.
