  • Surge/wave Simulators

    Suzhou 3ctest Electronic Co.,Ltd.

    Surge pulses occur due to direct or indirect lighting strokes to an external circuit. This leads to current or electromagnetic fields causing high voltage or current transients. Another source for surge pulsed is switching transients originating from switching disturbances and system faults.

  • Inductive Sensors

    Bernstein AG

    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.

  • Signal Converter

    ADDI-DATA GmbH

    The signal converter MSX-CVT-5VTTL is used in combination with Ethernet systems of the MSX-E or MSX-WL series and converts 5 V signals into 24 V signals for the trigger input. This allows, for example, using a 5 V encoder as trigger source to start the measurement process of length measurement transducers. The converter works with a push-pull output and can be mounted on a DIN rail for a reliable signal transfer through long signal lines and in an environment with electromagnetic interference (EMI). For use in harsh environments, in which a degree of protection is required, it is advisable to order the option OPT.MSX-E-5V-TRIGGER with the same converter function. This option is integrated on request directly into the system and cannot be added subsequently.
