Gefran confirms its application know-how as One-Stop Supplier for the mobile hydraulics sector with the new GR3P series of rotary sensors
Gefran, as One-Stop Supplier of hydraulics vehicles, launches GR3P, the new series of rotary position sensors with shaft, for a measurement range of up to 360° and equipped with a 3 PIN AMP Superseal connector.
E1 Omologation
Reliability, robustness and application flexibility: these are the characteristics of the new GR3P sensors with analog output, designed to ensure optimal performances even in the harsh environmental conditions of the mobile hydraulics environment. In this sense, the series combines durability and accuracy of the sensing element, typical of transducers based on Hall Effect technology, with a high degree of environmental protection (IP69K), resistance to shock (50 g) and vibration (20 g), which are key requirements for operating in this sector. In addition, the high electromagnetic immunity of the GR3P rotary sensors ensures interference-free operations even in construction sites or areas adjacent to high-voltage pylons. Possible applications of the series include: detection of the tilt angle of the extension arm of telehandlers, steering and accelerator pedal control of tractors, and harvesting system control of harvesters.
GR3P sensors are E1 approved for road use, an important added value that makes them ideal for installation on agricultural and construction machinery intended to travel short distances on roads.
A wide variety of mechanical configurations
Among the outstanding features of this range, the wide variety of mechanical configurations also stands out, benefiting high compatibility with different types of machines. This series consists of 10 models, respectively 4 in the 32 mm size and 6 in the 50 mm version, which differ in the distance and configuration of the two fixing holes and the length of the stainless-steel shaft. In addition, the PPA construction material offers high resistance against the various types of mechanical and environmental stress typical in the mobile hydraulics applications. While the fastening systems are available in circular or slotted design and with stainless steel and zamak reinforcement.
The GR3P sensors are available with four different actuation levers – made of plastic or steel – 50 or 80 mm in length. These can be ordered together with the sensor or, separately, via appropriate part number.
