TECHNOLOGY FILE  PRODUCTS USB CONNECTIVITY SOLUTION


Three new models have been added to Amplicon’s range of Digi AnywhereUSB devices. The AnywhereUSB is a network-attached USB hub that allows USB devices to connect to a PC by using existing TCP/IP network infrastructure. The units connect USB devices anywhere on a wired or wireless LAN, eliminating the need for local host PCs. The range provides units with either two, five or fourteen USB ports, all delivering


the same plug-and-play user experience as a local USB port. Software drivers are loaded onto a PC or server, enabling remote devices to communicate with the host without modifying existing application software. Peripheral devices can be centrally managed and monitored from a remote server or PC via an IP address.


The AnywhereUSB


range is compatible with bulk or interrupt type USB devices, such as bar-code scanners, printers, fingerprint scanners, mice, pole displays, card readers, flash drives and security keys.

DIN RAIL TERMINAL BLOCKS FEATURE PUSH-IN CONNECTION


Wieland Electric has introduced fasis WTP, a series of DIN rail terminal blocks with push-in connection. Designed for various wire cross-sections, these have a compact design and, with the use of high-performance contact technology, conductors and accessories can be plugged-in easily without the use of tools. The push-in connection technology is said to offer a high degree of flexibility. The connection options are multi-wire and fine-wired conductors with or without wire-end sleeve, ranging from 0.08 to 10 mm2


using only two terminal types – WTP 2.5/4


and WTP 6/10. In addition, the dynamic clamped connection compensates load-related and thermal dynamics, ensuring a durable mechanical and electrical connection.

ETHERCAT ABSOLUTE ENCODERS LAUNCHED


EtherCAT versions of Leine & Linde’s 600 and 900 series absolute encoders are now available from Mclennan. These feature the robust inductive scanning principle developed by the company, and are supplied with a choice of mechanical and electrical interfacing options. The EtherCAT encoders include powerful electronics that, in addition to the position information, can


deliver speed and acceleration values with great precision within each data cycle, allowing the PLC or motion controller direct feedback. In addition, the encoder interface also supports CANopen over EtherCAT according to CiA 301 and the device profile range CiA 406. With solid and hollow shaft variants available


across both ranges, the 600 series encoder offers a multi-turn position resolution to 31 bits whilst the heavy duty 900 series offers up to 35 bits. Both ranges offer a wide choice of alternative interfaces such as Profibus, DeviceNet, SSI and EnDat 2,2. With an adaptable network topology and


a flexible number of nodes in the system, EtherCAT is an easy to configure Ethernet system that can be set up for a cycle time of a few tenths of a microsecond, which is perfect for precision synchronisation, the company explains.

IN-LINE JUNCTION BOXES


New from Hylec-APL is DEBOX, an in-line junction box that is said to simplify and speed up installation. Each junction box is supplied as standard with a four-pole terminal block which is secured on a push-fit mounting pole. Furthermore, a ratchet arm is used to secure the cable within the junction box, which allows it to accommodate both flat and round cable whilst still producing secure cable retention. A fixing pin is used in place of a screw, clipping the lid in place quickly and efficiently; and the two mounting ears allow the DEBOX to be securely fastened in place, relieving tension from the cables.

Enter 240 RIGHT ANGLE OPTION ADDED TO SOLDER TERMINAL RANGE


According to Molex Incorporated, its SolderRight Direct Solder Terminals are now available to fulfill direct solder wire-to-board designs where a very low profile right angle solder option for wires exiting a PCB is needed. The robust one-piece crimp solder terminal


enables a secure and reliable connection with a minimal ‘z’ profile. Features include multiple terminal and wire sizes, solder pins positioned between insulation and conductor crimps, and twin solder pins. Terminal wire sizes range from 14 to 28 AWG, enabling both signal and power current capability while optimising PCB space. Solder pins positioned between insulation and


/ DESIGNSOLUTIONS


conductor crimps offer superior wire strain relief and resist terminal and solder join breakage. Molex twin solder pins provide stability for solder processing and allow redundant current paths. “The most common problem found in products that require a direct solder wire termination is that wires become over stressed from being bent at a 90 degree angle after soldering, resulting in long term reliability concerns. By replacing the soldering process with a direct board-in crimp terminal, this problem is eliminated,” explains Michael Bean, global product manager, Molex.
