Novotechniks TFD-4000 series short-stroke touchless transducer

Novotechnik’s TFD-4000 series short-stroke linear transducers are an ideal and economic solution where minimal size, high environmental protection, extremely long life and high reliability are key factors for medium to high-volume OEM position cont

Based on Novotechnik’s well proven RFD-4000 rotary sensor, the two-part non-contacting assembly comprises Hall sensor electronics - encapsulated and fully potted in a compact housing - and a separate magnet. The housing protection class options are IP67, IP68 or IP69K. With nominal dimensions of only 40 mm x 27 mm and a flat profile of just 7 mm, the sensor can be discretely assembled on the moving or stationary side of the measurement platform and the tiny magnet easily embedded within the opposite platform for a very low-profile measurement solution. Two standard magnets options are available to provide 14 mm or 24 mm stroke lengths.

The encapsulated design and touchless Hall Effect technology used on the TFD-4000 offers extreme durability with exceptionally high shock and vibration ratings, as well as a mechanically unlimited life. A temperature rating of -40 ... +125 ⁰C and full EMC compatibility will satisfy a wide range of applications from industrial controls to mobile machinery where short-stroke position measurement or where linear movement verification is required. The sensor is available with a choice of single, partly- and fully-redundant (c/w rising) ratiometric output from a  0…5 V DC supply. The update rate is 2.5 kHz and the standard model is supplied with 0.5 m long leadwires.

Customisation options for volume applications include special output characteristics such as trapeze or parabolic profiles and a wide choice of connector options.
