Rutronik Offers an Overview For Closing Bluetooth Attack Vectors

created by Sebastian Hör |   Knowledge

In mid-July, the Bluetooth Special Interest Group published instructions for eliminating security vulnerabilities in the “Secure Simple Pairing” and “LE Secure Connections” processes. Rutronik now offers a manufacturer-independent overview at rutronik-tec.com/bluetooth-security-vulnerability-status/, which shows the patch status of the individual chip and module manufacturers. The site is kept up to...

Crystals and oscillators for industrial Ethernet

created by Jochen Neller, Technical Support Inductors & Timing Devices at Rutronik Elektronische Bauelemente GmbH |   Knowledge

Industrial Ethernet enables continuous communication between actuators and sensors at field level and management systems. It also combines real-time capability with the robustness and security of fieldbus systems – which is why it is gradually replacing it. For Industrial Ethernet to also satisfy tough real-time requirements, crystals and oscillators of high signal precision and reliability are needed.

How is current measured using shunts?

created by Bert Weiss, Technical Support Resistors, Rutronik Elektronische Bauelemente GmbH |   Knowledge

The use of shunts for measuring current is a simpler and more cost-effective alternative to the use of sensors for current measurement. However, they are precision measuring devices, and a few things need to be considered to achieve measurements of the necessary precision.

How can sensors be powered with a battery for as long as possible in IoT applications?

created by Bianca Aichinger, Product Marketing Manager, RECOM Power GmbH; Co-author: Axel Stangl, Product Sales Manager Power Supplies, Rutronik Elektronische Bauelemente GmbH |   Rutronik

Without sensors, there can be no Internet of Things (IoT). The fact that they require power is often overlooked. Not much, mind you – but they cannot work without it. The latest switching regulators allow sensors to be powered for much longer using batteries. Even from a 4–20mA current loop, it is possible to produce three times as much power.
