A cable and hose management solution has been needed for an automated drill rod handling system on a Bauer deep drilling rig. Other than performance and ATEX-conformity, also longevity and service life were of importance. A KABELSCHLEPP hybrid energy drag chain now delivers all requirements.
Weidmüller's portfolio of products offers a broad spectrum of innovative and reliable components for installing photovoltaic systems. Designed specifically for use in photovoltaic systems Weidmüller offers two different versions of its 'WM4' plug connector – field and device/enclosure connectors. Operating solar systems demands reliability, safety and first-class performance of all the products – from the modules right down to individual connectors. Low contact resistance, first class workmanship and easy handling are distinguishing features indicating the right choice of connector. And it is exactly these requirements that both versions of the 'WM4' plug connector for photovoltaic systems fulfil. Not only are they supplied in proven Weidmüller quality they are also compatible with most connector mating profiles on the market today. 'WM4' plug connectors are designed with a huge connection capacity: a single crimp contact suffices to connect 4 mm² and 6 mm² conductor cross-sections. 'WM4' plug connectors are rated for current loads of up to 30 A. The rated voltage is 1000 VDC (IEC). When mated the 'WM4' field connector is sealed to IP 67 and the device/enclosure connector to IP 65. The 'WM4' is TUV approved and DIN EN 50521 compliant.
Weidmüller's newly developed FieldPower® LED has been designed for highly efficient and long-term luminous efficacy on the one hand and for deployment in harsh conditions on the other. These design features ensure the FieldPower® LED provides energy-efficient basic illumination in conjunction with an extended service life and facilitate rapid, error-free connection to the power bus. Moreover, this illuminating solution withstands even the harshest of conditions that prevail in the rotor hub of wind turbines, such as extreme shocks and temperatures. Designed to be extremely shock and vibration proof to EN 60721-3-3, Class 3M3 (mechanical conditions) it is possible to operate the FieldPower® LED in temperatures ranging from -40 °C to +55 °C. A wide input range of 110 to 265 V AC ensures it is possible to utilize the FieldPower® LED in applications across the globe. The integrated power LEDs offer a significantly longer service life as well as greater energy efficiency than fluorescent or energy-saving bulbs. Each FieldPower® LED reliably delivers the 10 and 50 lux light levels required by EN 50308: Wind Turbines. A special FieldPower® base facilitates routing pre-assembled and terminated cables into the pitch box with IP65 rating. A lid with integrated LEDs provides illumination inside the hub. The low power consumption of the LEDs results in only a low voltage drop in the cable, a fact that facilitates long power bus supply lines utilising conductor cross-sections of 2.5 mm² to 6 mm². A non-detachable, 2-meter cable from Heluwind (WK 103w-T 3G1.5 – AD 8 mm) is standard supply.
Weidmüller's product portfolio of Basic Line (unmanaged) and Premium Line (managed) switches includes Power over Ethernet (PoE) switches to meet the needs of industrial communication applications. Managed and unmanaged 6-port switches with four PoE+ ports are available. Utilizing the same cable Power over Ethernet (PoE) switches supply the required operating power to PoE enabled Ethernet components in parallel to data traffic. Typical PoE enabled connectivity components include WLAN access points, IP telephony and IP cameras. Routing data and power transmissions in parallel considerably reduces wiring costs. All PoE switches are operated from 24 V and supply PoE enabled Ethernet devices with up to 30 W of input power. This designed-in feature eliminates the need for an additional 48 V power supply module, which is required for most industrial PoE switches. Moreover, the managed-version supports remote on/off and reset control of connected PoE enabled end devices, for example via SNMP, WEB interface or HMI/SCADA systems in combination with SNMP or OPC. 6-port IEEE 802.3af/at PoE+ managed and unmanaged Ethernet switches boast four integrated IEEE 802.3af/at compliant PoE and Ethernet combo ports. Weidmüller's managed and unmanaged PoE Ethernet switches have extensive international approvals and certificates of conformity such as CE, FCC, UL/cUL Class I Div. 2 / Atex, DNV / GL.
With its 'FreeCon Active Repeater' Weidmüller offers a POF repeater with an integrated diagnostic function for deployment in PROFINET networks. Today, fibre-optics based on polymer optical fibres (POF) are increasingly being used, not only because they are immune to electromagnetic interference but because they are also able to meet the demands of automated applications for greater data volumes. However, these fibres are subject to a natural aging process, which successively increases fibre attenuation. That in turn increases the need for exact diagnostics of the transmission path. Weidmüller developed the 'FreeCon Active Repeater' in response to this need: to guarantee reliable transmission of the Ethernet data being transmitted the 'FreeCon Active' checks the entire transmission path in real time with regard to its optical budget – for example, from the electrical cabinet to the head of the robot. The device sends an alarm signal to a higher-level controller if a defined tolerance level is exceeded and the user needs to replace the cable set. By continuously checking the attenuation of fibre-optic transmission paths 'FreeCon Active Repeaters' now make it possible for the first time ever to precisely plan when to replace robot cable sets. The PROFINET POF repeater complies with AIDA specifications (Automation Initiative of the German Automotive Industry). In conjunction with the 'HTX-IE POF' multifunctional tool, which is designed to ensure rapid and repeatable preparation and termination procedures for SC-RJ type connectors, Weidmüller offers a complete all-round package of components for transmission solutions based on POF cabling.
VEGAPULS WL 61 is the first radar level sensor developed especially for the water/sewage sector. Compared to classic measuring techniques, such as ultrasonic, this modern technology delivers far more reliable measurement data and has proven highly successful in everyday operation.
The EKS Light from EUCHNER is a transponder-based access control system consisting of two components: an Electronic-Key with RFID transponder and an Electronic-Key adapter with integral read unit. The EKS Light was designed particularly for smaller, decentralized applications to permit reliable controlled access to individual machines or to entire installations there as well. The new FSA version of the EKS Light was specially developed to solve the widespread problem involving tampering of safety guards.
Lenze's tried and tested ECS servo system can now be ordered with a clock-synchronised EtherCAT interface. Combined with the new L-force Controller 3200 C for central control architectures, even the most demanding motion tasks in terms of number of axes and precision required can be solved effectively and economically.
In addition to numerous other innovations, mayr® power transmission is to present a large disengaging torque limiting clutch for torques of up to 280,000 Nm at the Hannover Trade Fair. This large clutch for heavy engineering is combined with curved tooth couplings for the connection of two shafts.
NORD Drivesystems supplies PROFINET modules for the integration of frequency inverters into PROFINET environments. In the second quarter of 2011, NORD introduced new modular units for cabinet-mounted SK 500E inverters while a version for distributed SK 200E-type inverters will follow in the fourth quarter.
