Advertorials New multiple transistor retaining springs


Depending on the application and its requirements, the mounting of electronic semiconductors to a heat sink, such as a heatsink, plays an important and non-negligible role. Various mounting options from the product portfolio of Fischer Elektronik GmbH & Co. KG in the form of different transistor retaining springs guarantee a high contact pressure as well as a permanent and reliable contact, and also a consistently good heat transfer between the device and the heat sink. For this purpose, Fischer Elektronik is expanding the above-mentioned product range of transistor retaining springs to include new universal multiple transistor retaining springs of the THFM 11... and THFM 20... series. The innovative multiple transistor retaining springs are made of 0.8 mm thick stainless steel and also have a low installation height. Furthermore, the contour and dimensions of the THFM 11... and THFM 20... retaining springs are adapted to the different types of transistors, such as TO 218, TO 220, TO 247, TO 248 and TO 264. The universal multiple transistor retaining springs have several individual retaining elements at a certain distance on a strip, whereby the number of retaining elements can be freely selected by the customer from 1 to 10 and adapted to the application. The retaining spring strip is attached to the heatsink or other mounting point by means of a screw connection so that the spring geometry presses on the device from above via the lever effect or, as an alternative mounting method, the transistors can be inserted under the spring. The listed innovations of the multiple transistor retaining springs as well as all innovations from Fischer Elektronik can also be found at www.fischerelektronik.de/en/

Röhm's IoT solution for real-time measurement of clamping force during machining does not even have a cable


Röhm presents the iJaw measuring clamping jaw at EMO 2021 in Milan


In Milan on September 30, 2021, the clamping technology specialist Röhm is presenting the iJaw clamping jaw for the first time at EMO 2021 in Milan. It allows the clamping force to be measured in real time during machining. Röhm thus solves a problem for which there has been no accepted industrial solution up to now: the clamping force is usually set by the operator of the machine tool and is a matter of experience. Errors during machining due to incorrect clamping force or workpiece loss are therefore preprogrammed. The iJaw presented by Röhm integrates sensor technology for clamping force measurement as well as wireless data transmission in a full-fledged clamping jaw. The measurement takes place directly at the clamping point to the workpiece; the data transmission to a gateway makes use of the upcoming industry standard IO-Link Wireless. The gateway can be connected to the machine control system via the integrated Profinet interface and/or sends the data to a cloud via the integrated LAN interface. Even on the most modern machine tools, workpieces are clamped today in the same way as they were


a hundred years ago: the operator clamps "by feeling". Due to the lack of sensors, the machine tool can only support the operator to a limited extent. And to ensure that workpieces are really “securely” clamped—no one wants to risk ejection—the clamping force is often set too high. Especially with thin- walled components or sensitive surfaces, this quickly leads to deformation and crushing.

Click: MIKROE adds high-performance signal generation for $109


Waveform 4 peripheral development board based on ADI's AD9106, quad-channel, 12-bit, 180MSPS waveform generator


MikroElektronika (MIKROE), the embedded solutions company that dramatically cuts development time by providing innovative hardware and software products based on proven standards, has launched Waveform 4 Click – a member of its +1000-strong Click family of peripheral development boards – that operates as a signal generator for high-speed, high-dynamic- range, multichannel complex waveforms required in applications such as ultrasound transducer excitation, medical instrumentation, portable instrumentation, signal generators, and arbitrary waveform generators. Waveform 4 Click features Analog Devices' AD9106, a quad-channel, 12-bit,


180MSPS waveform generator that integrates on-chip SRAM and direct digital synthesis (DDS) for complex waveform generation. The DDS facilitates a master clock sinewave generator at speeds of up to a 180 MHz with a 24-bit tuning word, allowing 10.8 Hz/LSB frequency resolution. The AD9106 has a single frequency output and independent programmable phase shift outputs for each of the four integrated DACs. More, the integrated SRAM data can include directly-generated stored waveforms, which can be accessed using the serial peripheral interface, amplitude modulation patterns applied to DDS outputs, or DDS frequency tuning words. Click boards are based on the 16-pin mikroBUS™ standard for sockets on a development board


invented by MIKROE ten years ago. Click boards enable design engineers to change peripherals easily, cutting months off development time. The company releases a new Click board nearly every day at 10am, and many leading microcontroller companies including Microchip, NXP, Infineon, Dialog, STM, Analog Devices Renesas and Toshiba now include the mikroBUS socket on their development boards.

NeoCortec signs agreement with Honeywell to develop wireless mesh technology for fire detection


NeoCortec, manufacturer of ultra-low-power bi- directional wireless mesh network modules, recently signed an agreement with Honeywell Building Technologies, a global leader in fire and life safety, to develop wireless fire detection devices that offer higher reliability, ease of installation and commissioning, and competitive cost of ownership. NeoCortec’s NeoMesh technology will be integrated


into Honeywell wireless fire detection products like smoke detectors, modules and audio-visual devices. “We are pleased to work with Honeywell to create a


new generation of wireless detectors that pair our wireless mesh networking protocol and stack with Honeywell’s expertise in fire detection,” said Thomas Halkier, NeoCortec CEO. Designed for versatility and use in different application areas, the NeoCortec NeoMesh wireless mesh


networking protocol and software stack is optimised for ultra-low power operation. NeoMesh is ideally suited for wireless sensor network installations where each device is required to send small packets of data infrequently. In such applications, NeoMesh can enable the network to operate on small batteries for several years. Unlike most other mesh network technologies, NeoMesh is dynamic and scalable with very few limits to network size or depth. “Wireless fire safety systems can offer property owners the agility they need to meet ever-evolving


occupant expectations as building spaces become more dynamic as well as saving costs when it comes to testing and maintenance routines,” said Jurgen van Goethem, vice president and general manager of Fire and Security for Honeywell Building Technologies.
