MECHANICAL AND LINEAR Magnetic clutches boost slip torque to 12Nm Mayr has expanded its Robacontitorque range of permanent magnet hysteresis clutch/brakes with a size 5 version that increases the slip torque range to 0.1–12Nm. The devices offer reliable, wear-free torque limitation in continuous slip applications. Unlike frictionbased devices, torque is transmitted without contact via magnetic forces, extending service lives and ensuring accurate, repeatable slip torque values. The compact, maintenance-free clutch/brakes can be used for load-holding, tensioning or torque-limiting applications. Their low weight and mass moment of inertia allow easy integration into a variety of applications. Optional sealed and corrosion-protected versions are available for use in almost any environment. Mayr Transmissions 01535 663900 www.mayr.co.uk Spur gears target everyday uses Ondrives has introduced a series of “competitively priced” spur gears for everyday uses. The gears are available with or without a boss, with various numbers of teeth and bore sizes, keyways, and tapped and pin holes. Sizes range from 0.5–6 Mod as standard with others available on request. Standard materials are steel and white Delrin. Most parts are available off-the-shelf with short turnaround times for parts not in stock. Modifications to standard parts and specials to customer drawings are available with short lead times. Ondrives 01246 455500 www.ondrives.com Large-bore SRBs last twice as long NSK has expanded its HPS range of spherical roller bearings up to 260mm bore. The bearings, known as the CAM series, are said to offer twice the lifespan and a 20% higher limiting speed than conventional spherical roller bearings (SRBs), resulting in cost and energy savings, and reduced maintenance. The improved wear resistance of the larger bearings under high speeds and mechanical loads enables them to cope with demanding applications. The bearings differ in design from the existing HPS-EA SRBs (up to 130mm bore) and have a guide ring for precise roller guiding, and optimised solid brass retainers which carry higher loads and offer high wear resistance. As well as increasing the lifespan and the wear resistance of the bearings, the design changes also increase their dynamic load rating by up to 25%. This can allow downsizing in high-loaded drive assemblies, cutting space and costs. NSK UK 0500 2327464 www.nskeurope.com COMMUNICATIONS Converters connect serial devices to Ethernet Brainboxes has introduced a range of Ethernet-to-serial converters that provide fast, reliable connections between Ethernet ports on a network and asynchronous serial interfaces. The one- or two-port RS-232 and RS-422/485 device servers support data transfer rates up to 230.4 kbd. The autonomous converters allow devices at the edge of a network to be managed from any connected location with the same control as if working locally. They come with drivers for Windows 7 and XP 32-bit and 64-bit versions. Brainboxes is packaging them with its Boost.net driver, keeping existing software applications on the network and allowing high reliability connections over long distances. The converters, which consume less than 1W, are housed in rugged metal enclosures. Brainboxes 0151 2202500 www.brainboxes.com IP67 box provides serial-EtherCat links Beckhoff has announced an IP67- protected module that can connect devices with serial interfaces, such as barcode or RFID readers, to EtherCat networks without needing a control cabinet. Using selectable RS-232 or RS-422/485 interfaces, the compact, two-channel EP6002 module integrates the serial devices into EtherCat networks. The module transmits the data in a transparent way to higher-level EtherCat controllers. The serial communication channels operate in full-duplex mode at up to 115.2 kbd. Serial devices are connected via rugged M12 connectors. When used with suitable software, the module can also be used without a controller as a COM interface in Windows-based systems. It measures 126 x 30 x 26.5mm. Beckhoff Automation 01491 410539 www.beckhoff.co.uk Gateway delivers wireless ZigBee-serial connections IDC has launched a gateway that acts as a ZigBee-to-serial interface connection, and can convert RS-232/422/485 serial devices, such as intelligent sensors and barcode readers, into wireless devices. The ZB103 gateway is designed for applications such as remote control and monitoring of machinery where cables are difficult to install, or for transferring data to and from mobile plant. The device can operate as a gateway for a network of ZigBee devices in factory automation, warehouse management and production monitoring systems, linking to a PLC via a serial port using Modbus or other protocols. The gateway complies with IEEE 802.15.4, providing two-way communications on the licence-free 2.4GHz band. It can connect hundreds of devices in a mesh network using gateways, routers and end devices (usually batterypowered). It is housed in a robust IP45 enclosure.
