Transceiver For Low-Power Wireless Sensor Networks

Rutronik has presented the MRF89XA from Microchip Technology, a transceiver with low receive current of 3mA for longer battery life in 868, 915 and 950MHz sub-GHz wireless networks. The 868MHz MRF89XAM8A and 915MHz MRF89XAM9A transceiver modules accelerate design cycles by removing the complexity of designing RF circuitry and the cost of obtaining agency certification. The sub-GHz frequency bands are sometimes preferred by designers for a range of battery-powered wireless sensor networks and metering communications.

In addition, the MRF89XA transceiver and modules integrate a 12.5dBm power amplifier for long transmission distances and a low-noise amplifier for -113dBm enhanced receive sensitivity. To ease communication and further prolong battery life, the MRF89XA combines an integrated packet handler with a 64-byte FIFO for transmit and receive buffering. The MRF89XA transceiver and modules are ideal for low-power wireless sensor and metering communication.

congatec Future-Proofs ETX and XTX Standard

Image
congatec AG, a leading manufacturer of embedded computer modules, is giving the ETX and XTX form factors a viable future with the integration of AMD Fusion technology. Modules based on AMD Fusion processors deliver significant improvements with regard to performance and scalability. Intel’s discontinuation of the 855 chipset family left a major gap in the market particularly for ETX computer modules, which primarily affected the higher performance range of applications. This gap has now been closed by processor manufacturer AMD with the Fusion architecture. Fusion also opens up new perspectives for a wide range of innovative and graphics-oriented applications.congatec has integrated the AMD Fusion architecture into its product range of ETX and XTX COM modules, opening up new scalability options for this form factor to meet even the most demanding tasks. The company supports the Fusion architecture with two new COM modules: conga-EAF and conga-XAF. While conga-EAF is an ETX module, co...

Haydon Kerk Motion Solutions Releases 36mm Linear Actuator Configuration that Replaces Existing 42mm Packages

Image
Haydon Kerk Motion Solutions, a premier manufacturer of linear motion products, has released a new version of its popular 36mm G4 linear actuator. This new configuration includes a special adapter plate that allows the smaller 36mm OD unit to replace 42mm and 46mm units in existing applications. Performance of the 36mm G4 linear actuator not only exceeds the performance of comparable size actuators, it approaches the performance of larger 42mm and 46mm linear actuators from various manufacturers. The 36mm unit with the integrated adapter plate allows users to replace existing 42 and 46mm units easily by using the same bolt pattern and pilot surface. Among the advantages of substituting the 36mm G4 linear actuator include a smaller linear actuator body, which is especially important when space is a premium, and a lower cost system, compared with the larger-size units. With the G4 linear actuator, both can be accomplished without sacrificing performance or lifespan. Force output rang...

Interalia Releases Single-Board Audio Announcer

Interalia Communication 's Trouncer provides a single-board digital audio announcer utilising onboard memory to allow large audio databases to be stored and updated via SD card. Ethernet connectivity and many other data-transmission formats ensure the messages are constantly updated for customer requirements, which enhances the use of PA systems and makes the Trouncer suitable for audio advertising. The system's design has incorporated many automated and manual methods of triggering the messages, including web-browser front ends, dedicated graphical user-interfaces tailored to site-specific requirements, and simple closed contacts from a relay or switch.
