The new sensor for Compact Directional valves

The new sensor from Rexroth which monitors the Compact Directional valves.

Magnetic sensor with no effect on switching times and hysteresis

Fork lift trucks, cranes installed on trucks or lifting platforms: Wherever people work with powerful technology for goods handling, increased safety regulations apply, across the globe. One basic requirement here is monitoring of the spool position of hydraulic valves, for example to prevent the boom of a crane from swiveling out too far. Rexroth provides reliable monitoring with their new sensor, as well as significant opportunities for savings at the same time.

A new sensor for directional and control valves monitors contact free, and therefore wear free, whether the coil of the valve is in the neutral or working position. This information is important for safety circuits that comply with standards and opens up new possibilities for diagnosis.

Users can monitor all hydraulic valves of a mobile or stationary application with this type of sensor. The compact sensor, which is directly installed on the valve, reliably monitors every movement of the valve spool and will indicate to the control electronic whether it is in the neutral position or working position as well as the direction of movement. In contrast to other measuring principles, the magnetic measuring principle does not have any effect on switching times or the hysteresis of the valve.

The sensor can make the measurement data available either in an analog or digital way. As a plug & play component it reduces the wiring work with a standard M12 connection with 5 pins. With the original plug from Rexroth, the sensor fulfills the important IP69K protection class for mobile applications. With these sensors, manufacturers guarantee the safety-relevant status monitoring of the valve and can use the data as an additional information source for diagnosis functions.

Software of the future: Freed from …

…the restraints of hardware – the software of the future. In the factory of the future, machine modules and processing stations will be regularly reorganized, flexibly take on new tasks and retrieve the appropriate software function. This change has already begun: Machine manufacturers are already able to install identical control functions on various device platforms without any extra effort. Here is an overview of concepts for today and tomorrow:

Bosch Rexroth expands additive manufacturing

The topic of additive manufacturing is becoming increasingly important in the production of small series and prototypes, as well as in the area of Industry 4.0. Bosch Rexroth also believes in this future-oriented technology. The company worked with TRUMPF and Heraeus Additive Manufacturing to develop a further additive manufacturing process for the cost-effective production of hydraulic components. With a focus on the Selective Laser Melting method, the project involved the production of servo valves. As an additional standard procedure to conventional production this can be used above all for quick production of small batch sizes and customized variants. Bosch Rexroth already uses several 3D printers for the production of casting cores for control blocks in Lohr and has expertise in the entire process chain from engineering to 3D printing to the finished product.
