PRODUCTS TECHNOLOGY FILE COMPACT CONNECTIVITY
New to Fischer Connectors’ FiberOptic Series is the miniature, lightweight and rugged FO1 connectivity solution. Offering high performance even in harsh environments, the connector is available either in pre-configured reels or integrated into custom assemblies for applications in instrumentation, sensing, defence, broadcasting, etc. The new connector meets the growing need for higher data transmission rates over long distances, while reducing space and guaranteeing performance by means of rugged miniature solutions. Of benefit, UPC & APC polishing reduces insertion and return losses, making devices more secure, while IP68 sealing provides highly valuable device protection. The push-pull locking system allows quick and easy connections and disconnections; and the removable sleeve holder (monobloc mate adapter) ensures that end faces can be cleaned easily. The FO1 connector has been tested to withstand temperatures of -40˚C, and can be pre-configured with Fischer FiberOptic Series reels of any
required length.

A BIPOLAR STEPPER MOTOR DRIVER IC
A new integrated bipolar stepper motor driver IC with built-in translator for easy operation has been launched by Allegro MicroSystems Europe. The A5984 is designed to
operate bipolar stepper motors from full-step up to 1/32 step modes that are selectable by MSx logic inputs. Features include an output drive capacity of up to 40V and ±2A and it operates with a single supply. The motor driver IC introduces a proprietary Adaptive Percent Fast Decay (APFD)
algorithm to optimise the current waveform over a wide range of stepper speeds and stepper motor characteristics. APFD adjusts, on-the-fly, the amount of fast decay with the goal of maintaining current regulation while minimising current ripple. This adaptive feature improves performance of the system resulting in reduced audible motor noise, reduced vibration, and increased step accuracy. The translator is the key to the easy implementation of the A5984; inputting one pulse on the STEP input drives the motor one microstep. It is supplied in three surface mount packages: two QFN packages – the 4×4mm,
0.75mm nominal overall height ES package, and a 5×5×0.90mm ET package; and a 24-pin TSSOP LP package.

Based on the Dassault Systèmes XCAD infrastructure, Theorem’s Multi-CAD solution allows CATIA V5 and 3DEXPERIENCE users to incorporate parts and assemblies from other CAD systems, such as NX and Creo, or visualization data in the JT format within the CATIA environment without having to use external translators. It does so by loading the files directly into CATIA and using the existing command of ‘Insert existing component’. Multi-CAD validates the integrity of the data as it comes into CATIA; and interlinking of the CATIA and foreign CAD data allows the user to work with different sets of data within a single interactive operation. This also supports the processing of Model Based Definition (MBD) information, which helps in
streamlining product development into a paper free process by publishing an information rich 3D CAD model that fully defines a product. By supporting MBD, Multi-CAD can also reduce the processing time of large CAD models as specific views can be filtered and processed at the point of output.

TERMINATE RIGID CABLES EASILY
Terminating larger more rigid cables on the DIN rail can be made frustrating when the terminals twist and go out of shape. To address the issue, Contaclip has introduced the SRK 35mm feed through and earth terminal. This is manufactured as a single piece
moulding for rigidity on the DIN rail when using larger cables.
IP55 ENCLOSED VSDS INTRODUCED
New to Mitsubishi Electric’s FR A800 series is a range of IP55 enclosed variable speed drives which are suited to harsher environments than conventionally packaged inverter drives. Designed to provide variable speed
control in demanding applications and where the control architecture is decentralized, the FR-A846 drives feature a high speed processor in addition to energy saving features and very low harmonics. The output range is from 400W up to 160kW. Additional features include an EMC filter, a DC reactor that ensures compliance with IEC 61000-3-12, a built-in graphical user interface, an LCD screen, a data logging functionality and a built in PLC. The IP55 series is suitable for operation
with both standard asynchronous machines and IPM/SMP motor technology. Maximum speed and

torque up to 590Hz can be achieved using the sensorless vector control facility; and an overload capacity of 200% during the start-up phase will ensure reliable starting cycles, even under demanding operating conditions. This also offers minimum terminal cycle times of less than three milliseconds, and speed rise times of less than 80 milliseconds. Two overload scenarios optimise system
planning, and functional safety is up to PLd/SIL3. Three slots are provided to allow for expansion cards such as extended input/outputs or network connectivity. Network options include CC-Link, SSCNET, Profibus-DP, Profinet, Ethernet/IP, EtherCAT, LONworks and Modbus RTU.

options include slotted or hexagonal M6 screws, and ‘Z’ versions have additional housing pegs which mate with adjoining terminals, providing an even more secure solution. The SRK\SSL35 have a spacious cable
entry; and the two cross connect channels and plug in cross connectors gives a fast, reliable and flexible connection.
