Novotechnik: Compact Touchless Linear Position Sensors

September 20, 2022

With a maximum sensor dimensions are 40 x 27 x 7 mm thin, the TFD Series of touchless linear position sensors from Novotechnik provides wear-free operation in tight spaces. The TFD Series offers sensing direction in either parallel or perpendicular direction to mounting holes, 

The TFD-4000 Series utilizes a magnetic position marker to provide a touchless measurement range of 0 to 14, 24 or 50 mm—depending on model. These sensors makes measurements through air and non-magnetic materials. Magnetic position marker mounts to users application.

Key TFD-4000 Series specifications 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.

The TFD-4000 Series sensors have analog voltage output and an operating temperature range of –40°C to +125°C.

Applications include textile machinery, packaging machinery, sheet metal machinery, medical applications, marine, mobile engine management systems, industrial trucks, construction machinery, agricultural and forestry machinery.
