Allegro MicroSystems Europe introduces new differential high-accuracy, high isolation current sensor IC with dual fault user settable over-current fault outputs

Allegro MicroSystems Europe has introduced a new high accuracy Hall-effect-based current sensor IC with multiple programmable fault levels intended for industrial and consumer applications with a focus on motor control and power inverter stage applications. One of the key benefits of Allegro’s ACS720 is to provide high isolation with a reduced bill of materials made possible by the proprietary IC SOIC-16W package.

UHF narrowband transceiver module

Power efficient radio solutions developer Radiometrix has introduced a new UHF narrowband transceiver specifically suited to power-constrained applications where existing single frequency wideband UHF modules cannot deliver the range required. Supporting data rates of up to 10 kbps, the NTR2 module provides a low power, highly reliable wireless data link, even in the most uncompromising of industrial settings. With an RF power output of 10 dBm and a receiver sensitivity of -118 dBm, its usable range can extend beyond 500 m.

 

Available in 434.075MHz, 434.650MHz and 458.700MHz versions, as well as customised options offered right across the 433MHz (EU) and 458MHz (UK) licence-exempt bands, these transceiver products combine effective screening with internal filtering to minimise spurious radiation and susceptibility. They conform to both ETSI EN 300 220-3 and EN 301 489-3 standards. In addition, they have an operating temperature range of -10 pC to + 60 pC.

Among the broad spectrum of applications that will benefit from the incorporation of these radio modules are EPOS equipment, barcode scanners, data logging systems, industrial/commercial telemetry equipment, in-building environmental monitors, high-end security/fire alarms, DGPS systems, and vehicle data up/download systems. Thanks to their compact dimensions (57 mm x 24 mm x 8 mm) and low levels of power consumption (drawing only 20 mA for transmitting and 15 mA for receiving), they will prove particularly appropriate for use in battery-powered system designs.
