Molex's expanded XRC line of extra rugged sealed
circular connectors are ideal for heavy-duty applications

Molex Incorporated (NASDAQ: MOLX and MOLXA) offer its line of sealed circular connectors. XRC™ (Extra Rugged Circular) sealed plugs and receptacles, available in an 18-shell/14-circuit size and 24-shell/31-circuit size. The circular connectors are ideal for heavy-duty applications such as construction equipment, marine, recreational vehicles, transportation and agricultural markets

In addition, the 24-shell size, 31-circuit connectors have a wire seal imprinted, instead of embossed or engraved, making it easier to see and identify each circuit for faster installation and field servicing. A backshell is also available for use with the 24-shell size products. The backshells easily snap onto the XRC housing after terminal assembly for increased strain relief.

Designed to meet IP67 standards, the Molex XRC plugs and receptacles are protected against the ingress of dust, water and other contaminants to maintain the integrity of the mated pair. Plugs feature a quick-disconnect bayonet latch to provide quick and easy connections with reduced installation and service time while ensuring accurate mating depth.

The XRC connector features a grommet retainer with a lip for compatibility with backshell and over-moulded applications. A large polarizing key indicator aids in visual alignment to facilitate easier mating. For further information, view website: www.molex.com/link/xrc.html  Refer to page 125

Belden Expands its Hirschmann™
portfolio with three new MACH100 devices:
rugged Gigabit Ethernet workgroup switches

These new Gigabit Ethernet switches, characterized amongst others by fanless (passive) cooling, can be used for connecting workgroups to the backbone in production environments using twisted-pair cables as well as optical fibers. Each of the three versions, designated MACH104-20TX-F, MACH104-20TX-FR and MACH104 TX-F-4PoE, provides 20 RJ45 ports (10/100/1000 BASE-TX) as well as four combination ports (100/1000 BASE-FX) for SFP fiber optic transceivers.

Further features include comprehensive management and redundancy procedures, various different configuration and diagnostic functions, high resistance to shock and jarring, and extensive insusceptibility to magnetic fields and electrostatic discharge. This is complemented by a redundant power supply on the MACH104-20TX-FR, and by four Power over

These new Gigabit Ethernet switches, characterized amongst others by fanless (passive) cooling, can be used for connecting workgroups to the backbone in production environments using twisted-pair cables as well as optical fibers.

Ethernet (PoE) ports with a rated output of 15.4 W per connected field device on the MACH104-20TX-F-4PoE. The required 48VDC voltage is directly generated from the 24VDC supply voltage in compliance with the regulations for electrical isolation as specified by IEEE standard 802.3af.

Redundancy procedures, such as HIPER Ring, MRP (IEC ring function), Rapid Spanning Tree and Link Aggregation provide high network availability. Security mechanisms include access control according to IEEE 802.1x, IP and MAC port security as well as SNMP V3 und SSH.

Detailed information can be displayed by means of a standard web browser. A further central management function is offered by an integrated SNMP interface, permitting e.g. the use of network management software such as HiVision.

The new MACH100 Gigabit switches are designed for an operating temperature range of 0 to +50 °C, assembly in 19" cabinets and plug-and-play commissioning. They can be configured by either means of Command Line Interface (CLI), Telnet, BootP, HiDiscovery, Watchdog Configuration or DHCP Server. If saved to an optional ACA 11 or ACA 21-USB auto-configuration adapter, all configuration data can be recalled at any time, if required.

With these three new Hirschmann™ workgroup switches, Belden has further expanded its leading position in the Industrial Ethernet segment. "All managed switches are based on a platform strategy for combining various Layer-2 and 

Layer-3 software packages with different hardware components," explains Product Manager Pascal Unterdorfer. Altogether, the product offering comprises over 10,000 device versions all operating under a consistent user interface. "This facilitates the realization of integrated data networks from the management to the control and through to the field level without the need for repeated training of the customer's personnel."

The PXI-2022/2020 provide a cost-effective solution
for automatic test equipment and acoustics application

ADLINK Technology, Inc., offer its PXI-2022/2020 high-density simultaneous sampling PXI DAQ boards. As one of  the later addition to ADLINK's extensive lineup of DAQ boards, the PXI-2022 and PXI-2020 provide 16-bit simultaneous sampling of devices at sample rates of 250 kS/s per channel across sixteen and eight channels, respectively. The PXI-2022 and PXI-2020 are ideal for applications that require simultaneous sampling over multiple channels, such as advanced physical research, radar, sonar, ultrasonic measurements, car engine test and aircraft noise monitoring.

Incorporation of the high-density PXI-2022 and PXI-2020 saves space and reduces the cost of developing PXI systems with multiple simultaneous DAQ modules.

The PXI-2022 and PXI-2020 feature flexible input ranges from ±2.5 V to ±10 V suitable for a wide range of applications. These boards also feature digital triggering, four digital I/O lines, and two 32-bit counter/timers.

The PXI-2022 and PXI-2020 include drivers and SDK support for mainstream Windows operating systems, as well as third-party applications including LabVIEW® and MATLAB®.

PoE+ PSE single port magnetic jack from Molex provides an
easy migration path from non-PoE to fully integrated PoE+ capability

Molex Incorporated has developed the first single port PoE+ Power Source Equipment (PSE), single port magnetic jack in accordance to the IEEE802.3at standard. Based on the RJ45 jack and backwards compatible with the previous PoE IEEE802.3af standard, the PoE+ PSE single port magnetic jack, series 85759, is a complete, plug-and-play module that provides engineers with a simplified design process and easy migration path from using standard power supplies to fully integrated PoE+ capability. 

"Prior to the introduction of the new PoE+ PSE single port magnetic jack, implementing PoE or PoE+ for a single port application required developing a discrete solution on the customer's board using custom controller silicon," explains Diarmuid Cullinan, Product Manager Integrated Products at Molex. "Power must be isolated from signal and significant design effort is required to protect the customer board from electro-magnetic interference (EMI) and electro-static discharge (ESD) while achieving all IEEE802.3at requirements."

The PSE-ICM offers the simplest solution for the design of a single port PSE. Eliminating complex design and testing provides OEMs with a faster time-to-market, reduced investment and lower direct and associated purchasing and production costs. "Except the power supply, the 85759 series contains the entire single port PSE; integrating the RJ45 connector with two LEDs, gigabit PoE+ Ethernet magnetics, and high-power PSE controller. All that is required is a simple 51V for PoE+ or 48V for PoE to automatically manage and control power to connected Ethernet devices such as colour-screen Voice over Internet Protocol (VoIP) phones, wireless access points and pan/tilt/ zoom security cameras," adds Cullinan.

The footprint of the Molex PoE+ PSE single port magnetic jack is designed to optimise the separation distance of the signal and LED pins from the PoE circuitry, significantly reducing the complexity of PCB routing. The module has an external reset feature and capability to set maximum PoE class requirements (maximum power delivery allowed). Multiple LED configurations and colours are available, including single and bi-colour.

Power over Ethernet (PoE) is a technology that defines the transmission of both data and power to networked devices over a standard Ethernet cable, eliminating the need for separate power supplies; PoE+ is the new IEEE802.3at standard. It provides the opportunity to increase port-power output to 30 watts, when set to Class 4. It supersedes the 15 watt (Class 0 to 3) IEEE802.3af standard, which was released 2004.

Additionally Molex offers the 85789 series gigabit PoE+ enabled magnetic Jack; PoE or PoE+ power can be sent or received through the connector with the PoE circuitry situated on the customer board. For non-PoE gigabit applications the 85793 series is available.
