TT electronics power steering torque sensor saves fuel

December 3, 2012  by  

 TT electronics said its non-contact power steering torque sensor uses less current and is smaller and lighter than existing solutions and thus helps make electronic power steering systems more compact, reliable and efficient.

Designed to sense very small differential angles, the SX-4428 Magnetorque II non-contact steering torque sensor is based on Hall Effect technology. The free-floating torque rotor within the device offers infinite rotational life. The lack of torque rotor friction means it does not wear out as in previous devices thus improving reliability and extending product life expectancy.

The sensor enables developers to program output levels and reduce the use of tight tolerances in the steering shaft, thereby reducing shaft machining costs. Compact packaging and lightweight construction mean that space and weight are saved in the overall steering system.  Supply current is less than 21mA, which contributes to system efficiency.

The smaller packaging and internal structure enabled TT electronics to reduce the amount of plastic used in the SX-4428 by 42%. The sensor fits TT electronics’ philosophy of reducing waste and unnecessary packaging, as well as helping its customers achieve their environmental goals.

Operational from -40oC to +85oC and resistant to shock and vibration, the new non-contact sensor provides both a technical and environmental solution for demanding advanced electric power steering systems.

  1. Hello dears,
    we are a company from Italy specialized in the spare parts distribution.
    We are interesting in torque sensors (all models) and we’d like to receive an offer for 1000 pieces each month.
    Looking forward to your prompt reply.
    Best regards
