Angle Sensors

Absolute angle encoders and optical angle sensors as well as potentiometers

The measurement of rotation angles in demanding applications often requires a technical adaptation of the angle sensor to the specific application environment. MEGATRON is your expert for these cases. Within the scope of our consultation, we select the most suitable variant for your project after an analysis together with you. The application itself always determines the choice of the product.

The best possible solution may require optimization of the product. In simple cases it is a customer-specific cable assembly, shaft geometry or programming of the output curve. In addition, we carry out fundamental adjustments to the product, which we implement even for relatively small quantities.

Our claim is to provide each customer with the best functional and economic result. By delivering on time, we accompany you until the end of the product life cycle of your application. A complete package exactly for your needs. This has been our motto for more than 60 years.

Guide for Angle Sensors

What is an angle sensor?

Angle sensors are used as a component in applications for the sensory detection or specification of mechanical adjustments. The name angle sensor indicates that the sensor system measures an adjustment in angular degrees. Usually an angle sensor is connected to the application via a sensor shaft and the position is determined by means of a rotary movement and direction of rotation. The angle degree detected in this way is reported as an electrical signal to an evaluation unit and provides information on the adjusted path in the application. In addition to the mechanical design of angle encoders, the sensor technology they contain is the decisive criterion for the optimum quality and function of the application.

Angle sensor technologies

The choice of different product variants is often so diverse, but their characteristics are often so specific to the various technologies that it can be difficult to choose the right product. Within the scope of our consultation, we discuss the optimal technical and economic solution with you. Online we provide you with a brief guide to the topic of angle sensors, which explains the subject briefly here. For further information, please refer to the respective guides.

Sensor technology:
The sensor technology is decisive for the quality and function of the application. The sensor technology significantly defines the sensor's properties. Please familiarize yourself with the advantages and disadvantages of the individual technologies depending on your application. Very often the choice can be narrowed down considerably.

Basic considerations for product decisions

Measuring range:
The measuring range of the angle that a sensor must measure is of particular importance when selecting the technology. This is because ranges up to 360° are covered with singleturn sensors and ranges above that with multiturn sensors, which can have different designs depending on the choice of technology.

Environmental conditions:
What size, design, mounting, mechanics, materials and protection class does the angle sensor have? Are there special requirements due to the prevailing environmental and application conditions? How long must the lifespan of the mechanics and sensor technology be? What actuation speeds can be expected?

Electrical interfaces:
Which interface is optimal with regard to the required quality of the signal, the information processing and which environmental factors have an influence? Are analog interfaces such as voltage or current, or digital ones such as SSI, SPI, SSI most useful?

Electrical connections:
Which connections are convenient for installation and maintenance? What space conditions, cable lengths or special environmental conditions must be taken into account?

How precise must the measurement be and which environmental factors can influence the measurement? What are the requirements regarding linearity, hysteresis, repeatability, temperature drift and many more?
