February 28, 2019 - Novotechnik, U.S. introduces the TF1 Series of touchless position sensors. The sensors are designed to be unaffected by strong magnetic fields and metal flakes or filings present in a user’s environment.
TF1 Series consists of an inductively coupled position marker attached to a moving rod/piece of the user’s application that requires a position measurement and the sensor with operational and programming status LEDs. While operating, LEDs indicate whether the sensor is operating and the marker within measuring range, out of range as well as indicating results of internal diagnostics for valid output from the sensor.
The physical properties measured by the TF1 are position, and for some of the digital interfaces: speed and temperature.
Key TF1 Series specifications include stroke lengths of 100 to 1,000 mm, resolution to 1 µm, absolute linearity of ≤ ±0.025% of full scale for analog and ≤ ±100 µm for digital outputs, reproducibility of ≤10 µm for ≤ 400 mm stroke lengths and ≤20 µm for >400 stroke lengths for analog outputs. A high-precision mode for digital outputs features repeatability to <5 µm. It has an update rate of >10kHz—equivalent to <100 µsec.
TF1 Series sensors are plug-in compatible with many existing sensors including magnetostrictive and resistance track sensors.
Other key TF1 Series specifications include operation within specifications with up to 100 g shock and 20 g vibration. The sensors are sealed to IP 67, have an operating temperature range of -40 to +85°C and unlimited mechanical life with floating position marker. Output interfaces include analog voltage or current, SSI, CANopen and IO-Link.
