Measuring the distance to metallic targets with micrometre precision can be carried out with the new P|Prox range of inductive distance sensors from ifm electronic. Featuring cylindrical bodies similar to those of conventional inductive proximity sensors, these are easy to install and set up. Their IO-Link communication also means they are easy to interface with almost any type of control system.


The sensors deliver accurate, repeatable results, continuously outputting distance-to-target data via IO-Link. When the highest precision is


required, simple one-point calibration, or even more accurate three-point calibration, is possible. In all cases, the results are completely unaffected by the type of target metal. Additional features include an IP69K ingress protection rating and an operating


temperature range of -25 to +70˚C. They are available in flush and non-flush mounting versions with 60mm long industry standard M12, M18 and M30 threaded stainless- steel housings. All types are resistant to the effects of external magnetic fields, and all incorporate four LEDs for local status indication. Their measuring range depends on the model, with flush-mount M12 versions, for example, having a range of 0.2 to 2mm, and non-flush M30 types having a range of 1.5 to 15mm.

The LK series strain gauge force sensors from Inelta Sensorsysteme are used to measure the load on rolling bearings by measuring the radial forces acting on the bearing technology. The LK series are compact measuring units for measuring radial forces in ball


bearings. The measuring body of the series, which is available for measuring ranges up to 200kN, is a bending beam that is attached via a central threaded hole. There are two grooves in the bearing holder for guiding the snap ring; and an index hole ensures exact positioning and measurement of the relevant direction of force. The sensors, which have IP54 protection and are designed for a compensated temperature


range of 0˚C to 40˚C, have deformation bodies made of stainless steel and a housing made of anodized aluminium. A low hysteresis of less than ±0.2%, and minimal temperature influence on the characteristic value and zero signal, ensure high measuring accuracy.

LEM and Semikron Danfoss have designed a new concept, called Nano, that merges the capabilities of LEM’s range of current sensors with Semikron Danfoss’s DCM half-bridge power module platform for high-power automotive applications. The collaboration results in a core-based sensor that is 60% smaller than anything previously available without any compromise on performance. The sensor makes it possible to completely integrate


the sensing function into the power module, minimising component footprint, simplifying assembly and keeping costs down, the company explains. In addition to being suitable for use with electric vehicle (EV)


traction inverters with the DCM platform, it is also compatible with other Semikron Danfoss power module platforms. The innovative idea behind the Nano concept was to design a


core-based current sensor that could fit into the unused space between the top side of the power module and the gate driver board. This enables the footprint of the current sensor to overlap with that of the power module. As a result, the Nano current sensor does not take up additional space in the inverter. As no additional components are required to fixate the sensor mechanically and connect it electrically to the driver board, this delivers the highest level of integration that a core-based current sensor can achieve. The Nano current


sensor is mounted on the DCM power module, which uses the latest generation of 750V and 1200V SiC MOSFETs and has a rated current of 200A to 1000A.

SICK’S Next-GeNeratIoN Dt80 DIStaNCe SeNSor SetS PreCISIoN StaNDarD


Equipped with high-performance time-of-flight measurement technology, the SICK DT80 1D laser distance sensor achieves unparalleled accuracy of ±2mm with a resolution of 0.1mm at ranges up to 80m. The sensor uses a class 2 eye-safe laser to detect, measure


and position on natural targets with no reflector. Designed to fit even the tightest of spaces in both mobile and stationary machinery, this has a robust metal housing and delivers resilient performance despite challenging environmental conditions. The outstanding precision and range of the SICK DT80 give it


broad scope across factory automation and logistics, both indoors and outdoors. In factory automation, the DT80 is expected to find uses in production line measurement and monitoring, bin and


stillage level sensing, position monitoring of moulds, coil monitoring and length measurement, e.g. in metal or wood processing. It can be used in automated transport vehicles and forklifts, e.g. for height detection of forks. The DT80 can also be deployed for precise vertical positioning of cranes and hoists, as well as on special-purpose, municipal and industrial vehicles. The DT80 will accurately detect an object that has up to 90% remission at a distance of 80m. For objects


with extremely dark surfaces and only 6% remission, it still achieves a range of 14m. It is quick and easy to set up using the icon-supported colour display; and four on-sensor LEDs show current status and settings. Alternatively, it can be configured using SICK’s HTML-based SOPAS engineering tool or using IO-Link. As well as enabling easy configuration, the DT80’s IO-Link connectivity enables data to be


transferred and exchanged between sensors, actuators and OT control systems. Compact in size (65 x 33 x 57mm), the DT80 has a cast zinc housing, durable PMMA sensor


window, IP65 and IP67 protection, and high shock and vibration resistance. sicK

proximity detection with reduced power consumption


A fully integrated proximity sensor, designed to increase efficiency and performance in consumer applications, has been launched by Vishay Intertechnology. Featuring a vertical-cavity surface-emitting


laser (VCSEL), the VCNL36828P combines a photodiode, application-specific integrated circuit (ASIC), 16-bit ADC, and smart dual I²C slave address in a compact 2.0mm x 1.0mm x 0.5mm surface-mount package. Compared to previous-generation solutions,


the sensor has a 20% smaller package, 20% lower idle current of 5A, and 40% higher sunlight cancellation up to 140klx. With a range of 200mm and a typical rated supply voltage of 1.8V, the device is designed to deliver superior proximity detection while reducing power consumption to increase efficiency in space- constrained, battery-powered, applications.
