Panel Mount Fuse Holders

I added a another page the other day, but because I didn't think it would ever produce any visits I waited till today before I blogged about it. Plus I just used all the other related links in the last posting. Anyway, the new page addressed Panel Mount Fuse Holders. Much of the text is a copy from another page, so until I update the listing it will never do well.

I also added another page which contain zero text; Panel Mount Components. Not sure why I added this page, but it is a new page ~ it will be one of those pages that never gets 365 views a year, I already have to many of those.

As with the other new additions, the new page address have been added to the html sitemap. Although they will not be added to the xml sitemap used by the search engines, as I only up-load a new xml sitemap every 3 months or so. But Google should be able to find the new pages regardless.

I still have a number of pic files I want to add to the site, so the next new page address will relate to one of those graphic files I have.

Press-on Connector Covers

I had a few yet to be used connector cover graphics so I added a new page to hold them.
The new page is called Press-on Connector Covers. The original page covered all styles of Protective Dust Covers. Both pages are part of the section on How to design Equipment Chassis.
This will be one of those page that will never see many page views. Although the page does not have a lot of text, the text it does have is a copy of the original page.

Equipment Rack Design

There's a section of pages out on the web site devoted to the topic of how to design an Equipment chassis. As in Designing an Electronic Equipment Chassis.
Within the section are a number of related topics to chassis design, for example Equipment Rack Issues. Below that, a page was added covering Equipment Rack Rails, which is linked both off the main page and the page it follows; Electronic Equipment Rack Sizes.

Yet another page that was added to hold a graphic, so it may be another month before any real text is added to the page. However when looking over the entire section it seems like a good tutorial on how to design or specify an equipment chassis.
At the very least it provides issues to think about and pitfalls to be avoided, over a span of 52 web pages.

Cable Harness Design Considerations

As part of the design section on how to design an electronic chassis, a page was added to cover Cable Harnesses. Or additional considerations to account for when you require a cable harness within a chassis.

When to Tie wrap a cable, how often a tie wrap should be used along a length of cable and additional issues not covered on the original Specifying a Cable Assembly page. I will be adding a sub-section on splices to cables on that new page as well.

Other pages that were recently added include;

Equipment Data Runs; covering Possible Data Rates. 8/11/09

I don't see any other new additions to the chassis design section in this blog. Of course pages get updated all the time. Here are some key phrases;

How do I know where to tie wrap a cable.

How often do I tie wrap a cable.

Can I put splices in a cable harness.

Equipment Cable Runs

A new page was added to the section on How to Design an Equipment Chassis. The new page covers Cable Data Rates vs. Cable Length. Of course it's a new page that was only added over the week end; but, it does have a nice graph that shows Cable length vs Data Rate.

Now there's not a big calling for cable length data within a 16 inch chassis, but this section does cover rack gear as well. So rack to rack cable length could be a concern. Also the new page will support articles on Cable Assemblies and other pages relating to rack and chassis cable selection. So the page may not be all that relevant to chassis design, but it can't hurt. Plus soon other pages that do relate to cable length will soon be pointing to it, so it should be a nice addition to the web site once some data and text is added to it.

The group of pages that make up the electronic chassis design consists of about 50 pages.
Worst performing pages; looks like a tie between two pages;
Rack Mounted Temperature Alarm Units.
Rack Mounted Air Flow Alarm Units.

Equipment Rack Grounding

As part of the section on How to design an equipment chassis, a page covering Rack grounding has been added. The new rack page will help to support section 7 which covers Equipment Rack Issues, as well as section 6 which covers Grounding Issues.

All pages support the topic covering Chassis Vendors. The last time a page was added to this section was May 21, with the addition of Rackmount Computers, and Cable Retractors.

I think at this point the information in the section covers the topic pretty well. Not real sure how easy it is to navigate the section, but each page provides a link back to the contents page...

Industrial Rackmount Computers

As part of the section on how to define an equipment chassis specification, two new pages were added.

The first page covers Industrial Rackmount Computers. The Industrial computers page provides a few design hints and a listing of companies that produce industrial PCs. The original list of industrial PCs had resided on the Manufacturers of PC Chassis page. The PC chassis vendor page now only holds commercial products.

The second new addition covers Cable Carriers or Cable Retractors. A Cable Carrier helps manage cables between the equipment chassis and the chassis rack. Using a cable retractor insures that the cable assembles bends and moves the correct way as a chassis is being moved in and out of a rack. Cable retractors also insure that the cable does not bind on any thing behind the chassis or within the rack. Within a few days the page will also cover Cable Retractor manufacturers.

Also added two more chassis specifications to the chassis standards page. Of course the main page in the section now lists the new page additions. Two new link additions to the section include; Fuse Derating, and Power Supply Standards. Also fixed the link to manufacturers of Anti-Vibration products, which happened to be pointing to the Rack Leveling products page by mistake.

The purpose of the entire section is to show a novice how to design an equipment chassis, or how to write a specification so an OEM could design the chassis. In any case the pages provide many design hints and engineering guidelines as well as some do's and don't s concerning electrical equipment design.

The industrial equipment design section spans 46 pages with links to other relevant topics on the web site. Don't get burned when purchasing an equipment chassis, review the different section that are relevant to the chassis your designing.

The page covering manufacturers of chassis has a link to the top page in this section.
