HX & HXN
DC, AC and pulse small currents' measurements from 3 to 50ARMS nominal with galvanic isolation
HX, HXN - Small-Size Current sensors
The HX and HXN families consist of current sensors engineered for the electronic measurement of DC, AC, and pulse small currents ranging from 3 to 50 ARMS nominal with galvanic isolation.
Both product lines feature a compact design and small size at competitive prices. With a mere 2.93 cm² of PCB mounting area required to accommodate their 8g weight, these sensors offer a measuring range of up to 3 times Ipn and provide a voltage output. They are designed for PCB mounting.
The HX sensors are offered in 17 models across 3 different versions, supporting dual supply of +/- 12 to +/- 15V and single supply of +12 to +15V. On the other hand, HXN sensors are available in 8 models, all supporting dual supply of +/- 12 to +/- 15V.
Within the HX family, there are two variations: HX-P and HX-NP. The primary distinction between these series lies in the HX-NP's design with 2 insulated primary windings.
Both HX and HXN product series are predominantly intended for industrial applications, leveraging hall effect technology for current measurement.
