TR-0025

Manufacturer reference: 400023261

He Novotechnik TR-0025, article 400023261, it's a short-travel industrial potentiometric linear sensor, designed for continuous linear position measurement in automation applications, industrial machinery, test benches, assembly equipment and displacement control systems with high requirements for repeatability and mechanical robustness.

This model belongs to the renowned series TR/TRS from Novotechnik, a family of compact linear transducers based on technology from conductive plastic, designed to offer an analog signal proportional to displacement with excellent long-term stability and high mechanical durability.

The reference TR-0025 / 400023261 has a defined electrical range of 0…25 mm, with a 30 mm mechanical stroke and one independent linearity ≤ ±0.2 % FS. Its extremely compact design 18 x 18 mm It allows for integration into machinery with limited space, while maintaining a robust and reliable industrial construction.

Unlike the TRS version with a circular connector, the TR-0025 incorporates output via a 2-meter shielded cable (3 x 0.14 mm² AWG26, PVC jacket), facilitating direct connection to PLC, conditioning electronics or signal acquisition systems.

The sensor uses a multi-finger cursor made of noble metal, cushioned by elastomer, working on a highly stable, conductive plastic resistive element. This design provides excellent repeatability of ≤ ±0.002 mm and a lifespan exceeding 100 million movements, even in continuous operation applications.

One of its main differentiators is its stem guided and supported on both sides by DU sliding bearings, This robust construction allows the probe tip to absorb high lateral forces. It is particularly well-suited for cam tracking, mechanical probing, inclined profiles, or mechanisms with lateral contact.

The casing is made of anodized aluminum AlMgSi and the drive shaft in AISI 303 / 1.4305 stainless steel, with anti-rotation protection and M2.5 x 6 internal thread. The assembly incorporates a probe tip with a hardened metal ball, allowing for precise and repeatable mechanical contact.

He Novotechnik TR-0025 potentiometric linear sensor It has a nominal resistance of 1 kΩ, maximum supply voltage of 42 VDC, resistance to vibrations according to IEC 60068-2-6 (20 g), shock resistance according to IEC 60068-2-27 (50 g) and degree of protection IP40, with a working thermal range of -30…+100 ºC.

Due to its performance, it is an excellent solution for OEM applications, industrial automation, manufacturing machinery, testing systems, assembly devices, medical equipment and building automation where robust, compact and highly repeatable linear measurement is required.
