TRS-0025

Manufacturer reference: 400023271

He Novotechnik TRS-0025, article 400023271, it's a short-travel industrial potentiometric linear sensor, designed for continuous linear position measurement in automation applications, industrial machinery, assembly equipment, test benches and displacement control systems.

This model belongs to the series TR/TRS from Novotechnik, a family of compact potentiometric transducers with internal return spring. Its reduced section design 18 x 18 mm It allows for easy integration into limited spaces, while maintaining a robust construction for demanding industrial applications.

The version TRS-0025 / 400023271 has a defined electrical range of 0…25 mm, connection via M16 connector and one independent linearity ≤ ±0.2 % FS. The mechanical stroke corresponding to size TR/TRS-0025 is 30 mm, while the electrical measurement range indicated by Novotechnik is 0…27 mm. For the commercial reference TRS-0025, the defined working range is 0…25 mm.

The principle of measurement is resistive potentiometric, with output type voltage divider. The resistive element is made of conductive plastic, and the cursor uses a noble metal multifinger system with elastomeric damping, providing a signal proportional to the stem displacement. To maintain the specified performance, the sensor must be used as a voltage divider with virtually no load on the cursor.

One of the differentiating points of Novotechnik TRS-0025 potentiometric linear sensor is his drive stem supported on both sides, using DU sliding bearings. This construction allows for better resistance to lateral forces at the probe tip, for example in applications involving cam tracking, inclined plates, or mechanical contact elements.

The casing is made of anodized aluminum and the stem in AISI 303 / 1.4305 stainless steel, with anti-rotation protection and M2.5 x 6 internal thread. The included probe tip is made of stainless steel, with M2.5 external thread and a pressed hardened metal ball.

Electrically, the TRS-0025 operates with a nominal resistance of 1 kΩ, resistance tolerance of ±20 % and maximum supply voltage of 42 VDC for this stroke length. The specified repeatability for the series is ≤ ±0.002 mm, with a typical temperature coefficient of 5 ppm/K.

The sensor is designed for industrial environments with vibrations and mechanical shocks. The datasheet specifies vibration resistance according to IEC 60068-2-6: 20 g, 5…2000 Hz and shock resistance according to IEC 60068-2-27: 50 g, 11 ms. The sensor protection is IP40 according to DIN EN 60529, with a working temperature of -30…+100 ºC For versions with an M16 connector, the stated service life is greater than 100 million movements.

Due to its characteristics, the Novotechnik TRS-0025 It is especially suitable for position measurement and control applications in manufacturing machinery, woodworking machines, riveting machines, packaging machinery, welding machines, assembly and testing devices, medical equipment and building automation.

When a standardized signal is required for PLC or acquisition systems, the TRS-0025 can be combined with signal conditioners to obtain industrial outputs such as 0…10 V either 4…20 mA.
