Inductive Sensors
-
In general, inductive proximity switches consist of four basic elements: a coil, an oscillator, a threshold switch and an output stage with short-circuit protection.The oscillator generates a high frequency, electromagnetic alternating field which is emitted from the active face of the coil.Eddy currents are induced in a metal object that enters this field. These eddy currents draw energy from both the electromagnetic field and from the oscillator which is consequently attenuated.The more energy taken the closer the metal object moves towards the active face. The threshold switch switches on the output stage at a defined attenuation value.In proximity switches with a DC voltage supply, this switch is designed as an NPN transistor which switches the connected load to the negative pole or as a PNP transistor which switches the load to the positive pole. The output stage is a thyristor or a triac in AC voltage switches.

Specific Absorption Rate (SAR) Testing
-
SAR limits are there to protect all of us from wireless devices that exceed the transmit Radio Frequency (RF) threshold. SAR stands for Specific Absorption Rate. It's a measure of the rate at which energy is absorbed by your body when you are exposed to an RF electromagnetic field. In some countries, the SAR test result figure has to be displayed at the point of sale. To have a presence in these markets, your products must meet strict SAR regulations.

Surge Generators
Hybrid
-
Surge pulses occur due to direct or indirect lightning strikes in a circuit or by switching transients caused by switching inductive loads or short circuits. This leads to currents or electromagnetic fields causing high voltage or current transients. Surge voltages and currents can reach several thousands of volts and thousands of amperes. Our following Surge generators simulate these disturbances for all the necessary level in accordance with IEC / EN 61000-4-5 and IEC / EN 60060.

RF Test
-
RF is short for radio frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum.

Is a physics modelling package for electromagnetic fields and charged particles. A CAD component allows the definition of mechanical parts and assignment of electric potentials, magnetization and charged particle sources. A time domain, particle-in-cell (PIC) tool then solves the electromagnetic fields and moves the particles within them. The particles’ own charges andmotions are fed back into the electromagnetic fields allowing the effects of space charge and selfmagnetism to be accounted for.
