The history of portable electronics is one of decreasing size, both for the devices themselves and the batteries to power them. A while back, I reported on the Quad A battery—specifically, Energizer’s push to make the Quad A more commercially available. The Quad A was commercially available (though not prevalent) since 1989. Similarly, the technology behind Energizer’s latest offering, the Zinc Air Prismatic Battery (or ZAP for short), has been around since 1991.
Built with TPMOV surge suppression technology, Ferraz Shawmut’s new Surge-Trap surge protective devices (SPDs) comply with the UL 1449 Third Edition standard. The units exhibit modular-style IP-20-grade “finger-safe” protection, and mounts on a DIN rail to safeguard critical electrical system components from transient overvoltage effects. The devices suit system voltages from 120 V to 600 V, and are MCOV rated from
Measuring up to 26.2’ (8 m), Gems Sensors & Controls' UCL-520 Series ultrasonic level sensors are suitable for non-contact fluid applications, such as industrial water treatment, wastewater management, and chemical storage. The two-wire ultrasonic transmitter offers a PVDF transducer, a 8” min. dead band, a 3” min. beam width, and a selectable display indicating levels in air gap or liquid height. The device is push button calibrated with
Using common wire gauges in cable lengths up to 10 meters, FCI’s DensiShield I/O links exhibit 10 Gb/s per channel differential performance. The differential performance can be achieved at 6 meters or less by utilizing 30 AWG cable, at 8 meters or less by utilizing 28 AWG cable, and at 10 meters or less by utilizing 26 AWG cable. The devices meet the 10GBase-CX4 Ethernet and Infiniband industry standards. The products accommodate
Bundling with a PICMG 1.0 Core2 Quad/Dual or Pentium 4 single board computer (SBC), Advantech’s IPPC-7158B 15” industrial panel PC exhibits a passive backplane with up to 12 ISA/PCI expansion slots. The unit consists of a XGA TFT LCD, a front-accessible design with water resistant cover; a flat-sealed front-panel, and an aluminum detachable side-open front panel (NEMA4/IP65 compliant). The model includes
Offering sizes of 12.70 mm², 15.88 mm², and 19.05 mm², EAO Switch’s Series 95 color-changing pushbuttons allow up to 2 (12.70 mm²) or 3 (15.88 mm² and 19.05 mm²) LEDs to be added. The 24-mm high (max.) devices have an N/O self-cleaning gold-plated switch element rated at up to 48 VDC/50 mA. The units are suitable for mounting on PCBs between 1.50 mm and 2.50 mm thick and can be snap-mounted to the PCB. The switches
Configuring up to 64 channels in a single system, GaGe’s Octopus CompuScope 84XX 16-bit digitizers offer 2, 4, or 8 digitizing channels in a single PCI card. The products present up to 4 GB of on-board acquisition memory, base memory of 128 MS with up to 2 GS optionally available, and 10 MS/s or 25 MS/s sampling per channel. The devices support timestamping, clock in/clock out, trig in/trig out, and a 10-MHz reference clock. Optional
This podcast is a discussion of MEMS and nanotechnology in the international marketplace, and is part of a series on disruptive technology done in conjunction with Hannover Fairs, and is intended to be a snapshot of the MEMS Nanotech facet.
Distributed power means different things to engineers. Some think of it only as the distribution of different DC voltages on a circuit board or in a rack of equipment. But good power-distribution engineering starts at the power company's connection to a building's wiring and goes all the way down to IC power inputs.
Using a buck topology, Supertex’s HV9919 SSLD uses a hysteretic control function to maintain its output current between a fixed minimum and maximum level at all times. The PWM controller performs in solid-state lighting applications, such as industrial, architectural, signage, or decorative lighting; indicator or emergency lighting; and as a general-purpose, constant-current source. The component offers programmable dimming frequency via
Able to deliver from 50 W to 150 W, the CS060 Series heater from Omega Engineering has a double-insulated plastic case for touch-safe operation. The clip-mounted device is intended for use with water, automotive, and food-processing applications. The CE-compliant heater is designed for permanent operation and is compatible with the company’s
Based on optical insulation technology and sigma-delta modulation, Avago Technologies' ACPL-785J Series isolation amplifiers integrate short circuit and overload detection. The 10.3-mm × 10.2-mm × 3.5-mm SO-16-packaged components allow direct measurement of motor phase currents in power inverters. The devices demonstrate 1-µV/°C offset change vs. temperature, CMR of 25 kV/µs at 1,000-V VCM, and a min. bandwidth of
Providing a PECL or LVPECL output with a frequency range from 200 MHz to 1 GHz (245.76-MHz STD), Valpey Fisher’s VFVX100 VCXO targets universal edge QAM. The 9-mm × 14-mm SMT component exhibits <0.20-ps jitter and phase noise of -142 dBc/Hz at 10 KHz offset for 622.08 MHz. The RoHS 6/6-compliant device offers
Combining visible-light capability with IR imaging, the FLIR i-Series thermal-imaging IR camera from Extech Instruments can provide a scalable and independently-adjustable picture-in-picture “fusion” image of the target showing both the visible target outline and the IR focus spot in the same frame. The pistol-grip device has a 3.5” LCD and comes in versions with image-capture resolutions of 120 × 120, 140 × 140, or
