The AEMC MA114 MiniFlex 14 in. Current Sensor (3A/1mV/mA, 30A/100mV/A, 300A/10mV/A, 3000A/1mV/A) is an AC current sensor composed of a flexible Rogowski coil and an electronic module. The sensor permits measurements on conductors where standard clamp-on probes cannot be used. It can be installed in tight spaces, around cable bundles, bus bars, or even wrapped around irregular shapes.

The Miniflex has a mV output proportional to the current measured for direct readings on DMMs, loggers, oscilloscopes and power or harmonic meters. The length of the flexible sensor is 14 in. (35cm) and clamp around conductor up to 4 in. (10cm). Four ranges are available, 3A/3V, 30A/3V, 300AV3V and 3000A/3V. The model MA114 is power by AA batteries or by a standard mains adapter (5Vdc, 100mA) by a type B micro-USB connector.
