FWAxxxTR
Displacement Tracer, Potentiometric Type

● Resistor and collector paths made from conducting plastic.
● Suitable for direct measurements of displacement without a form-locking connection, position detection at stationary measuring objects, tolerance measurements and for continuous contour measurement.
● The pull rod, which is supported on both sides, allows for accepting transverse forces that, for example, occur during a continuous scan of curves or spline parts.
● Rear limit stop is used to provide a simple mechanical
coupling of automatic retraction systems, such as pneumatic cylinders or electromagnets.
● Long life span of 100 x 106 strokes, extraordinary linearity up to ±0.075%, tracer pin running on two exact bearings, DIN compliant standard measuring inserts can be used, shock and vibration resistant.

▒ Pre-adjusted in the factory by storing the correction
values in the ALMEMO® connector.
The precise adjustment can be locally performed by the
user with final measures after the installation.
