Conductive Plastic Motion Transducer Elements (KIT),

up to 1000 mm

The LMF is a reduced bulk, precision motion transducer,

designed for easy integration into equipment.

FEATURES

• Measurement range 25 mm to 1000 mm

• High accuracy ± 1 % down to ± 0.025 %

• Good repeatability

• Simple and flexible mounting

• Essentially infinite resolution



Made in two separate parts:



- the sensing element



- the wiper



Special designs available on request

• Material categorization: for definitions of compliance

Note

• Nothing stated herein shall be construed as a guarantee of quality or durability.
