Weidmüller's Power over Ethernet switches: managed and unmanaged 6-port switches with four PoE+ ports. – New PoE+ Industrial Ethernet switches for industrial communication applications.

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.


Weidmüller's 'FreeCon Active Repeater': PROFINET POF Repeater for diagnosing light signals. – Complies with AIDA specifications (Automation Initiative of the German Automotive Industry). – Multifunctional tool HTX-IE POF for terminating SC-RJ connectors.

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.

Proven in practice

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 Controller 3200 C with EtherCAT to control the ECS servo system

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.


Limiting high torques reliably. New torque limiting clutch for heavy engineering.

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.

PROFINET Technology Unit: The interface for distributed control and cabinet-mounted inverters

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.

New Anybus CompactCom Modbus TCP 2-port module eliminates external switches

The new 2-port version of Anybus CompactCom for Modbus TCP is not only a fast and easy way for industrial device manufacturers to achieve connectivity to Modbus TCP. It is also a way to reduce the need for expensive external switches and cut down on factory wiring since the module comes with a built-in switch of its own.
