FOR THE PAST several years, we have complained loudly about the dearth of real new products. Thanks to the worldwide recession, reduced research and development monies at vendor companies across the board, and falling product sales, what we’ve been seeing in these monthly product roundups have been slightly warmed over versions of last year’s products. Few companies have spent development money on new, truly advanced products.
Instead, many companies just change the color scheme or install a gold-plated screw on last year’s gadget, call it a new product, and send us a press release. In years past, we would ignore such products, because we don’t like to publish products that are more than a year old (yes, we can tell). These product roundups are supposed to be limited to all the new products in a given niche announced in the past year. This lets you see how products have developed and identify any trends.
Alas, for the past couple of years, we’ve had to run the “gold-plated screw” products, just to fill these pages. In some cases, because of the lack of products in a category, we’ve had to (blush) run last year’s products again.
In this month’s roundup on I/O, wiring and terminals, we finally get to see some ingenuity and cleverness at work, as vendors seem to have broken out of their new product doldrums and are starting to generate great gadgets galore. As near as we can tell, what you will see on the following pages and on our web site are all new products, not warmed-over versions.
Wireless, Ethernet and fieldbus products dominate the scene, as vendors have been scrambling to make their products fit into the digital world. Nearly every I/O product in this roundup has either a wireless, Ethernet or fieldbus connection. A few even have advanced capabilities: one power switching relay controller has a built-in web server, and one DeviceNet device allows remote diagnostics.
Several of the new terminals and connectors work with fieldbus. To make your job a little easier, one company offers a 24-hr delivery service for wiring, cordsets and connectors, while another offers a design-build service for custom enclosures and wiring.
