TFD-4000 Series Touchless Linear Position Sensors

Sept. 17, 2022
Novotechnik's TFD-4000 Series makes measurements through air and non-magnetic materials.

The TFD-4000 Series of touchless linear position sensors makes measurements through air and non-magnetic materials and provides wear-free operation in tight spaces. The series uses a magnetic position marker to provide a touchless measurement range of 0 to 14, 24 or 50 mm, depending on the model. Sensing direction can be either parallel or perpendicular to mounting holes.


Key features include ingress protection from liquids and dust to IP67, resolution of 12 bits, repeatability of ? 0.1% of full scale, and optional second channel for applications requiring redundancy.


TFD-4000 Series sensors have analog voltage output and an operating temperature range of -40 to +257°F (-40 to +125°C).
