Miniature voice coil motor

The miniature LVCM-019-022-02 Linear Voice Coil Motor, also called a linear DC motor, has a ½-in. (12.7-mm) stroke and a high force-to-size ratio. It produces 8.1 oz. (2.3 N) of continuous force and 25.7 oz. (7.1 N) of peak force in a compact 0.750-in. (19.1-mm) diameter x 0.875-in. (22.2-mm) housing. This miniature high-speed / high-acceleration servo motor may be used in closed-loop servo loop. This zero-cogging, clean, quiet, efficient, low-inertia, high-acceleration, miniature voice-coil motor is suitable for pick-and-place, testing, laser steering, laser speckle reduction, mirror positioning, scanning, oscillation, switching, clamping, and haptic feedback in handheld medical, dental, or industrial applications.

WR-28 waveguide dual bandpass filter

Model SWF-25301340-28-B2-D is a Ka-band waveguide, dual-bandpass filter with passband frequencies from 24.25 to 25.25 GHz and 36.25 GHz to 40.0 GHz and rejection frequencies from DC to 23.8 GHz, 27.0 to 35.5 GHz, and 42.0 to 49.0 GHz. The filter is designed for 5G frequency bands and 24-GHz and 38-GHz system applications, particularly. The nominal insertion loss of the bandpass filter is 3.0 dB and the typical rejection is 40 dB. Since the passband frequencies can be changed by modifying the design, custom designs can be offered under different model numbers. Sage Millimeter

2000W high-input voltage DC-DC converter

ABSOPULSE Electronics has released the LQC 2K-3U2LC, a liquid-cooled, industrial quality DC/DC converter that delivers up to 2000 W of output power. The unit accepts an input of 600 VDC (400-VDC to 800-VDC range) and provides 24-VDC/80-A output. A built-in output separation diode allows parallel connection of several units for higher system output. Custom input/output voltages are also available. The LQC 2K-3U2LC liquid-cooled converter is designed for dense enclosed spaces where heatsinks, fans, or pure convection cooling are not feasible. The unit is typically used in vehicles, industrial automation, and similar heavy-duty applications. ABSOPULSE Electronics

48V 480W DIN rail power supply

The TDK-Lambda DRB480-48-1 AC-DC DIN rail-mount power supply, with an efficiency of up to 93%, allows the use of a compact enclosure size featuring a power density of 6 W/in. The power supply is suitable for a range of industrial applications including factory automation, process control, and test and measurement, particularly where there is limited room on the DIN mounting rail. It has an operating input range of 90 to 264 VAC and can deliver 48 V at 10 A. The output can be adjusted from 48 to 52.8 V to offset voltage drops in cabling or where OR-ing diodes/FETs are used in a redundant configuration. TDK Corporation

Ultrahigh-accuracy power analyzer

Vitrek’s PA920 Series Ultra High Accuracy Power Analyzer (accuracy of 0.024% of reading) integrates awideband waveform digitizer with advanced computational capability, a large high-resolution display, and a full-color touchscreen user interface. The multichannel PA920 offers 0.024% power-measurement accuracy for all channels (one to four channel cards available per unit), innovative VPA architecture, 100 full precision readings per second, and measurement bandwidths sufficient to handle 5-MHz signals. The unit’s intuitive touchscreen operation — with built-in data history, scope mode, and waveform zoom — allows detailed power measurement. Vitrek

Real-time spectrum analyzer

RIGOL's RSA3000E spectrum analyzers bring the power of UltraReal real-time analysis to customers who previously had no access to this advanced capability. The RSA3000E combines a high-performance swept spectrum analyzer with the analysis capability of a real-time analyzer. The RSA3000E is available in 1.5-GHz and 3-GHz models with available tracking generators and a starting price of $1,799. The instrument comes standard with 10 MHz of real-time analysis bandwidth with seamless capture and a 9.3-ms 100% POI. The RSA3000E provides the same seven visualization modes and triggering capability as RIGOL’s other UltraReal products, at a lower entry price. RIGOL

High-performance LGA socket

The Model CBT-LGA-5019 LGA Socket meets high-performance requirements for 1-mm-pitch optical engines. The contactor is a stamped spring pin with 19-g actuation force per pin and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.93 nH, insertion loss is < 1 dB at 23 GHz, and capacitance is 0.097 pF. Current capacity of each contactor is 4 A. Socket temperature range is -55°C to +180°C. The socket features an IC guide for precise LGA edge alignment. The specific configuration of the package to be tested in the CBT-LGA-5019 is LGA, 33-mm x 33-mm body size, 32 x 32 array, and 1-mm pitch. Ironwood Electronics

Simplified hardware-based IoT security

Microchip Technology Inc. has introduced a preprovisioned solution that provides secure key storage for low-, mid-, and high-volume device deployments using the ATECC608A secure element. Microchip’s Trust Platform for its CryptoAuthentication family enables easy, secure authentication. Microchip’s Trust Platform consists of a 3-tier offering, providing out-of-the-box preprovisioned, preconfigured, or fully customizable secure elements, allowing developers to choose the platform best suited for their individual design. The first tier of the Trust Platform—Trust&GO—provides zero-touch preprovisioned secure elements with a minimum orderable quantity (MOQ) as low as 10 units. Microchip
