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.
