Hooker Electronics Ltd. www.hookerelectronics.com Monday, November 29, 2010 Looking for MIL SPECS I have found searching for MIL SPEC quotes very difficult. As I do not always know exactly what I am looking for, I can get locked into a price that is not competitive. I just found a great resource from a member on LinkedIn and I thought I would post the website for those who have found themselves in the same position: The DSCC web page. Here is link search section for mil spec's http://www.dscc.dla.mil/search/ Posted by Julia Moroney at 5:41 AM No comments: Email This BlogThis!

Shell Eastern Petroleum Ltd (SEPL) recently completed its Ethylene Cracker Complex (ECC) on the island of Pulau Bukom – Singapore using Hirschmann™ WLAN technology to develop plant-wide wireless process control system. The full project included modifications and additions to the existing Bukom refinery. The application required the following WLAN products: • outdoor access points together with accessories • antennas • surge arrestors • managed switches • media converters • Industrial HiVision For security Belden/Hirschmann team used the EAGLE firewall system The backbone was built with Belden’s PROFInet copper and fiber optic cables and Lumberg Automation™ Ethernet M12 connectors for all Ethernet devices. In places where where wired LAN access was challenging , the Belden/Hirscchmann team enabled connectivity with easy-to-manage wireless point to point links.

Power over Ethernet (PoE) is an IEEE 802.3af standard that enables common data transmission and energy over a network. PoE is a process where devices, such as switches, are supplied with power directly via the data cable, for example, via a CAT 5/5e cable up to 100m. PoE is power distribution through the data cable from the rail to the backbone. Why Use PoE? With PoE network planning is less constrictive as you can design your network without having to use switch cabinets and sockets. In addition, you will not incur any extra cost for the electricity and telephone network (VoIP) wiring. With PoE you can save the power supply cable and, install devices with an Ethernet interface, such as switches, in places that are difficult to access or in areas where lots of cables would be an interference. PoE increases the fail safety of connected devices by using uninterruptible power supply (UPS). For example PoE can maintain the energy supply when the supply voltage to a switch fails so that the network availability is increased considerably.
