AWG to mm² Conversion Explained: Wire Sizing for Safety and Performance (Sponsored)

AWG Conversion Calculator

It is of fundamental importance across a broad range of electrical projects to ensure the right wire size is chosen for the given application. Accordingly, then, there are few more critically needed skills among electricians and engineers than knowing how to convert from AWG to mm2. Before we go any further, let’s quickly set out these two units of measurement: “AWG”, of course, refers to American Wire Gauge – a standardised wire gauge system that goes back to the mid-19th century. As its name indicates, AWG is predominantly used in North America. In Europe and elsewhere in the world, however, millimetres squared, or “mm2”, see widespread use for directly measuring a cable’s cross-sectional area, or CSA. In some contexts, then, you might see AWG being used, while in others, references to wire size may be in mm2. Being able to quickly convert between these two systems will help ensure both […]

Sony AS-DT1 tiny industrial LiDAR depth sensor can operate under bright conditions (up to 100,000 lux)

Sony AS DT1 LiDAR sensor

Sony AS-DT1 is a tiny and precise LiDAR depth sensor, which the company claims is the world’s smallest at just 31 x 29 x 29mm and the world’s lightest at 50 grams compared to other solutions with a range of 10 meters or more. It is designed for applications such as drones for inspections and surveys, autonomous mobile robots, food service robots, and warehouse automation.

SPARK Microsystems SR1120 UWB ultra-low-power transceiver delivers up to 41 Mbps throughput

SPARK SR1120 UWB transceiver

SPARK Microsystems SR1120 is the company’s second-generation ultra-wideband (UWB) wireless transceiver capable of up to 41 Mbps throughput at ultra-low power and up to 100 times lower power ranging than UWB competitors. The Canadian company also highlights the outperformance of their UWB solution over Bluetooth with the new SR1120 offering 40 times higher data rates than Bluetooth chips, while consuming 25 times less power than Bluetooth and offering 60 times lower latency. However, readers should note that Bluetooth LE is supposed to support up to 2 Mbps, so it should (only) be up to about 20 times faster, and Bluetooth HDT is coming soon with data rates of up to 7.5 Mbps to further narrow the gap. SPARK SR1120 key features and specifications: Compliant with the upcoming IEEE 802.15.4ab low-energy UWB PHY standard Dynamically reconfigurable UWB spectrum 6.2–9.5 GHz band Up to 3 dBm TX power RX sensitivity of -81 […]
