From March 1st, 2021: Pewatron will become Angst+Pfister Sensors and Power

Pewatron AG and its sister company, Pewatron Deutschland GmbH are serving industrial and medical customers around the world with advanced sensors, power supplies, power electronics and drive solutions. Both companies are 100 % owned by the Angst+Pfister Group since many years. This successful cooperation is to be further highlighted and even extended for the future by implementing the new brand Angst+Pfister Sensors and Power.

The sensors and power business has always been an integral part of the Angst+Pfister Group. In fact, Pewatron is serving most of the same customers as the group. At the same time the market trend to integrate electronic functions directly into the customer´s application is getting more and more important.

”By introducing ´Angst+Pfister Sensors and Power´ we want to demonstrate our commitment to further extend and invest into our sensors  and  power  business  as a cornerstone of Angst+Pfister´s growth strategy”, says Thomas Röttinger, CEO of Pewatron. In addition, the new brand will reflect the close cooperation between the Angst+Pfister developers team and the Pewatron product engineering team in the evolution of sensing solutions based on the joint know-how in both, elastomer based materials and sensorics. “Sensing materials are finally becoming a reality”, Röttinger explains.

In early 2021, a rebranding campaign will  be kicked off to properly introduce the new brand to all customers, suppliers and other stakeholders. In parallel Sensors and Power will be integrated into the new Angst+Pfister website and is planned to be launched as well on March 1st. Apart from the new company name and mail addresses all contact  data for the Sensors and Power team will remain unchanged. More information:

Integration of digital technology greatly simplifies the use of magnetic field sensors

In addition to the seal components, the magnetoresistive sensors from NVE also make the operation of pneumatic and electric actuators more secure.

The Smart Sensor technology  from  NVE is a great example of how the use of magnetoresistive (MR) sensors in electric actuators can be simplified considerably through forward integration.

Electric actuators or pneumatic solutions are used in challenging yet safety-related systems as drives for linear cylinders, damper actuators, rotary drives or swivel drives. Reliability of the individual built- in components is a key priority for these applications. As the NVE Smart Sensor is an electronic product and thus sensitive  to moisture, these components must be protected against dust, dirt  or  moisture in a housing by the right selection of seal components.

The drives move over a specified distance. The path length or the approach are detected by a sensor that is positioned either next to or along the axis (e.g. at the end point of the path). In many cases, the axis itself is already magnetised or the magnet sits at the end of the axis.

The SM228 Smart Magnetometer from NVE comes into play here. This new sensor integrates the discrete components required to convert the recorded signal into a tiny 2.5 x 2.5 mm housing. The signal is processed on site and the results are transmitted through the standard interface, e.g. transmitted to a microcontroller.

The benefits of such an integrated solution are clear. All components are coordinated for the defined work area and calibrated accordingly. The SM228 can be configured for applications according to specific parameters via the  existing  interface.  The TMR technology used in the SM228 allows three switching characteristics.

  • Bipolar: the sensor is switched on with a magnetic north pole and switched off with a south pole.
  • Unipolar: a magnetic north pole is activated when the threshold  value is reached and deactivated when the magnetic field falls.
  • The third option offers security against external interference. The SM228 can thus be programmed to ‘its threshold values and can no longer be influenced by other external interference magnetic fields (burglar protection, e.g. windows, doors).

«The new Smart Sensors will significantly advance the projected strong growth of the IoT.»
