1 Special-Sensors for Automation Functional safety at Power supply pulses up to 4 KV Frequency converter spectra High frequency radiation up to 0 V/m ISO 900 certified

2 Electromagnetic interference Power supplies to electrical equipment and sensors increasingly employ technologies which generate pulsed currents or voltages, or currents or voltages with superimposed oscillation (so-called pulse-width modulation). In contrast to sinusoidal waveforms, the voltage or current pulses used have very steep slopes/edges that can generate a very broadband interference spectrum, which can cover a spectrum of up to 0 MHz. High frequency technologies in a frequency range up to 2 GHz, which are used for the wireless transmission of digital signal sequences, are also problematic. In addition to this electromagnetic noise, communication networks transmitting control signals or data can be a further source of interference, e.g. power lines (digital signal transmission through conventional power supply lines), WLAN (wireless local area networks), or cell phone, TV, and radio networks, which use antennas as repeaters. These sources can generate interference voltages which wirelessly impair nearby signal lines. It collects the surrounding interference signals and, depending on line length and interference frequency, transfers them directly to the sensor electronics. Depending on interference strength and frequency, they can impair the sensor electronics. Interference voltage / V ,5 20 Frequency / MHz Fig. 2: Interference voltage induced in a sensor supply line, installed parallel to a frequency-converted motor supply line MHz Motor Frequency converter Power supply Field strength V/m 0 00 MHz Sensor Power supply unit Fig. : Parallel power supply lines to motor and sensor The parallel guide of a sensor supply line and motor power supply can be problematic if the motor is driven by a frequency converter (Fig. ). For example, when using a 20 m supply line, a kw motor can generate an interference spectrum peak voltage of more than 200 volts in the 20 m line running parallel and in close proximity. (Fig. 2) The power supply line of a sensor works like a receiving antenna; the same applies to fieldbus lines. 0, Distance / m Fig. : Progression of the electrical field strength based on distance to transmitting antenna with a transmitter power of watts Radio transmitters generate very high field strengths near transmitting antennas, which can significantly interfere with sensor functions. Apart from a direct effect on the sensor, the sensor supply line also contributes to this problem since it works like a receiving antenna. The interference potential of the effective field strength is specified in V/m (volt per meter). The EMC standard requires an interference resistance of up to 5 V/m for proximity switches. Interferences from walkie-talkies or separately installed transmitting antennas can significantly exceed this value (fig. )..02 EE04 EGE-Elektronik Spezial-Sensoren GmbH

3 The effects of the electromagnetic interferences transmitted to the sensor line can be reduced by selecting high quality power supplies equipped with integrated interference filters. Sensors used in extreme environmental conditions can also be fitted with rejection filters and suitable components that meet higher demands than those of customary standards. The demanding environment sensors offered by EGE are designed specifically for rugged environments in which sensors are exposed to high electrical, electromagnetic or mechanical stress. Stress types which typically occur in various industrial environments are often not covered by standard inspection and test methods. Therefore, EGE has developed special test methods that are adapted to testing sensors for critical applications. This has resulted in sensor designs that are suitable for use in almost any environment. Table provides an overview of some data on EGE proximity switches that exceed standard requirements.
