5.1 Measuring range
All the technical data of each Temposonics
®
 sensor are checked and 
recorded at the nal quality inspection. At the same time the active 
electrical stroke is programmed.
NOTICE
On all sensors, the areas left and right of the active stroke length are
provided for null and dead zone. These zones should not be used for
measurement, however the active stroke length can be exceeded.

5.2 Mounting instructions
 1. O-ring and back-up ring have been fitted at the factory.
 2. Lubricate O-ring and back-up ring before mounting into  
the cylinder.
 3. Push the sensor into the seat carefully. Make sure that the cables  
and conductors are not under strain.
 4. Carefully route the cables through the cylinder wall.  
Avoid tensile stress acting on the connecting cable.
 5. Never expose the connecting cable to tensile stress and protect it  
against sharp edges. Sharp edges could damage the insulation of  
the connecting cables.
 6. The bending radius of the cable must not be less than  
25 mm (0.98 in.)
 7. Terminate the wires on the controller side per the electrical  
connection table (refer to chapter 4.3, Fig. 4) regularly.
