The new 424Dxxx Angle Sensor from elobau features high precision paired with extraordinary robustness.
Depending on the model, it can execute angle measurements ranging from 20° up to a complete circle ranging from 0° to 359°.
The non-contact design provides exceptional reliability. The measurements are made with a magnetic field whose rotation is detected with a non-contact Hall sensor. Another benefit of this construction principle: the sensor does not require a limit stop. Thanks to its IP 67protection class, the sensor is protected against all effects of dust and water which may be present in industrial processes and in vehicles. Other features are short-circuit protection, electromagnetic compatibility as per DIN 40389 for automotive applications as well as high-quality and durable ball bearings for the rotating axis. Operating temperatures range from -25°C to +85°C (-13°F to +185°F).
The unit’s resolution of 0.1 degrees with a signal refresh rate of 300 Hz is evidence of it high accuracy. The angle sensor also features a highly homogeneous signal curve with a maximum linearity error of ± 1 percent. The analog output optionally ranges from 1 to 5 V, 4 to 20 mA or 0.5 to 4.5 V. With these features, the 424Dxxx Angle Sensor can be used for almost any mechanical or automotive engineering application.

AC operated Rotary Variable Differential Transformers (RVDTs) measure rotary position up to +/-60degs. Like AC LVDT’s they contain no signal conditioning and are therefore chosen for their smaller size and use in hostile environments.
Description: RVDTs incorporate a proprietary non-contact design that dramatically improves long term reliability when compared to other traditional rotary devices such as syncros, resolvers and potentiometers. This unique design eliminates assemblies that degrade over time, such as slip rings, rotor windings, contact brushes and wipers, without sacrificing accuracy. High reliability and performance are achieved through the use of a specially shaped rotor and wound coil that together simulates the linear displacement of a Linear Variable Differential Transformer (LVDT). Rotational movement of the rotor shaft results in a linear change in the output signal, directly proportional to change in shaft angle, over ±60 degrees from the null position. The phase of this output signal indicates the direction of displacement from the null point. Non-contact electromagnetic coupling of the rotor provides infinite resolution, thus enabling absolute measurements to a fraction of a degree. The R30A and R36AS RVDTs are AC operated rotary transducers. AC excitation of 3 V rms results in a ratiometric AC output voltage that varies in direct proportion to the change in angular position of the transducer shaft.

The combination of a coder with ends of the road in the same case increases the reliability and the safety of the machines, because of two independent checking circuits in the same case.
The coder integrated provided information uninterrupted of the movement in 5-30 VDC with a resolution from 100 to 5000 increments. The programmable ends of the road, the catch of origin are regulated freely with the position wished.
The adjustment of the ends of the road is very simple: the case is assembled on the machine, the machine is then led manually to its limiting position, the end of the road is positioned with a key of programming. This procedure is repeated for the other end of the road.
The case is well protects by its cap against dust or any external intervention; all the signals are cabled on a connector with the back of the case.
These cases can also be provided with potentiometers.
COMP' AUT will be able to best advise the customer in the choice of the case being appropriate for its application.
