Mayr Introduces Vertical-Axis Braking Solution

Mayr Power Transmissions has unveiled the Robaa-topstopa, a fully sealed drive-side-mounted safety brake suitable for any vertical- or gravity-loaded axis. Designed to meet the demands of EN ISO13849-1, the compact and lightweight Robaa-topstopa can be retrofitted to existing servo systems to prevent uncontrolled vertical movements in a power-off or emergency-stop situation.

The Robaa-topstopa is available as a single- or double-circuit brake with either a shaft output to connect to a gearbox or an integrated plug-in coupling to enable connection directly to a ballscrew. Available in three standard sizes ranging from 12Nm to 170Nm, the Robaa-topstopa is said to offer safe and reliable braking even with the motor removed. With a housing sealed to IP54 and flanges that can be adapted to any application, the Robaa-topstopa provides a simple, safe and economical vertical-axis braking solution, according to the company.

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...
