Low-power MCU

The power-efficient 16-bit M16C/26 microcontroller is an ultra-low power MCU for performance up to 20 MHz for commercial, automotive, and industrial applications. By integrating a voltage down converter, the unit can operate at a full-rated 20 MHz across a wide voltage range of 3.0-5.5V, a key for applications like gas, water, and electric meters, as well as remote security systems. Hyper New DINOR flash technology is not affected by process variations because it creates memory cells; MC16C flash memory MCUs handle 100,000 erase/write cycles.

Models come with RS-232 computer interface and traceable calibration certificate. OMEGA Engineering, www.omega.com. Enter 637

Short-body sensors

Ex-protected versions of IM08, IM12, and IM06 advanced short body inductive proximity sensors have high switching distances and frequencies despite their small shapes. The sensors are protected against shock, and dust and dirt; conform to NAMUR; and are designed for material handling, machine tools, and other systems. They have no moving parts and no contacts, detect metal objects, and come in shielded and non-shielded versions. Sick Optic-Electronic, www.sickusa.com. Enter 638


A real-time oscilloscope series captures four, full-bandwidth signals and provides sample rates of 20 Gsamples/s per channel. The series is available in 4 to 6 GHz. According to the manufacturer, when units are paired with the industry's fastest probes-InfiniiMax active probes-at 3.5 to 7 GHz, the system is ideal for verifying the performance of high-speed digital products. With up to 32 Mbytes of memory per channel, these oscilloscopes capture more information up to and after the event. Agilent Technologies, www.agilent.com. Enter 639
