Position sensors GRA - Agent of Gefran in Vietnam


Position sensors GRA - Agent of Gefran in Vietnam


Rotary sensor for measurement ranges up to 360° with ability to program analogue versions of ±15° steps.

Contactless Hall technology for almost infinite sensor life due to absence of wear on the sensing element.

Various configurations make the product easy to install on vehicles.

High IP protection level, resistance to shock and vibration, and high electromagnetic compatibility make these products suitable for many mobile hydraulics applications.

Developed to ensure a robust and high-performance solution for applications such as agricultural machines, construction machines, material handling equipments.
