LED Curing Epoxy

EpoxySet, Woonsocket, RI, introduced UV-8701E blue light LED curing epoxy that can be cured with 365- to 405-nm light sources in less than 10 seconds with a cure shrinkage of less than 1%. Once cured, it produces a rugged, semi-rigid plastic with a glass transition temperature of 138 °C. It offers temperature cycling from -50 to 180 °C as well as moisture and chemical resistance. The thixotropic adhesive with a color change indicator bonds to plastics such as ABS, Ultem, and polycarbonate as well as glass, ceramic, and metals.

Thermal Gap Filler

Laird Performance Materials, Cleveland, OH, introduced Tflex HD80000 high-deflection thermal gap filler combining 6 W/mK thermal conductivity with pressure-versus-deflection characteristics. The combination allows minimal stress on sensitive components while also yielding low thermal resistance. The filler can be handled and applied manually without the need to add fiberglass or other reinforcement layers and is designed for operating temperatures from -40 to 150 °C with low outgassing. It is available in ceramic-filled silicone sheets in standard sheet sizes of 9 × 9" or custom die cut parts.

Network Analyzers

Keysight Technologies, Santa Rosa, CA, offers the E5080B, P50xxA, and M980xA series network analyzers in benchtop, USB, and PXI form factors. The analyzers combine built-in pulse generators and modulators, spectrum analysis, and time domain analysis in a single instrument. The devices enable simplified test setups that can be reconfigured and calibrated, and eliminate loss from extra connections and external switches. Features include automatic fixture removal, time domain analysis, basic pulsed-RF measurements, scalar mixer/converter measurements, gain compression measurements, and spectrum analysis.

HART-to-Wireless Adapter

SignalFire Wireless Telemetry, Marlborough, MA, introduced the Link Scout that wirelessly adapts to loop-powered 4-20mA HART® instruments for HART connectivity with asset management software. By tunneling HART traffic over the 900-MHz platform, the device allows users to configure, calibrate, and troubleshoot assets equipped with a HART-enabled instrument using DTM software. The HART-to-wireless adapter does not interfere with the operations of loop-powered devices as it is independently powered by a battery and wired in parallel with the existing signal.

Data Transceiver

The SCT2400 transceiver from CML Micro-circuits, Maldon, Essex, UK, is designed to sustain secure digital voice and data communication channels over ranges in excess of 12 km (line of sight). The integrated digital radio transceiver is based on spread spectrum modulation operating in the 2.4 GHz frequency range. The range of over 12 km with up to 100 mW of output power is achieved while consuming 10 mA in scan mode or 52 mA when receiving voice and 64 mA when transmitting voice.
