TS2651N141E78 Tamagawa (also sold as variants like TAMAGAWA TS2651N141E78 BRT ENCODER and TS2651N141E78 Tamagawa Smartsyn Brt Resolver), one of Tamagawa Seiki’s well-known industrial feedback sensors:
The Tamagawa TS2651N141E78 is a high-precision brushless resolver designed for robust rotational position sensing and feedback in demanding motion control systems, particularly in servo motors, robotics, automation, and CNC machinery. It belongs to Tamagawa’s Smartsyn/BRT resolver family, which combines the durability of traditional resolvers with enhanced signal quality and environmental resistance. Unlike digital encoders that produce digital pulse signals, this resolver generates analog sine/cosine voltage signals proportional to shaft angle, which are then converted into digital position feedback by accompanying electronics.

Mechanically, the TS2651N141E78 typically features a hollow shaft design (approximately 14 mm diameter) that facilitates direct integration into motor or drive systems without complex coupling. The body is compact and lightweight (around 0.3 kg), making it suitable for space-constrained applications. Its brushless construction ensures maintenance-free operation and high reliability over long service life. encodermarket.com
Environmental performance is a key aspect of this resolver: it can operate across a wide temperature range (often from about −55 C up to +155 C), and withstands significant vibration (~196 m/s² at 10–500 Hz) and shock (~981 m/s²), making it suitable for harsh industrial environments. Its robust design also provides excellent noise immunity and long-distance signal transmission capability, attributes critical in industrial automation. Eltex Srl+1
In operation, the TS2651N141E78 accepts an AC reference excitation (typically around 3.5–10 Vrms at ~4 kHz) and outputs proportional analog signals that represent absolute shaft position. These signals are then used by a motion controller to determine speed and position for precise control. Its absolute position detection and high-speed capability (often up to ~8 000–10 000 rpm) make it a reliable choice for feedback applications in modern industrial motion systems. en.peymanelc.com+1
Overall, the TS2651N141E78 is valued for its precision, durability, environmental robustness, and maintenance-free performance in industrial feedback and control systems.
