Touchless linear position sensor
Novotechnik's TFD-4000 Series utilizes a magnetic position marker to provide a touchless measurement range of 0 to 14, 24 or 50 mm.1
Novotechnik introduces the TFD Series of touchless linear position sensors provide wear-free operation in tight spaces. Maximum sensor dimensions are 40 x 27 x 7 mm thin. 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 IP 67, 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. They have an operating temperature range of –40°C to +125°C.
