Power-Over-Ethernet is predicted to have a significant market impact, doubling its already-solid acceptance over the next few years. Providing power, as well as connectivity using existing wiring, it makes it simpler to install Web cameras, VoIP phones, wireless LAN Access Points and other appliances. Bel Power Inc. is supplying half-brick dc-to-dc converters that power these units. The half bricks use Microchip's MCP6291 low-power, high-bandwidth op amp and PIC12F675 microcontroller to sense current and monitor power consumption, updating parameters in firmware to help engineers avoid the expense of redesigns.
Linear guides are one of the most important components required for the development of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides in machine design, can enable designed-in functional features.
