HX Series – Small Size Hall Effect Current Sensors
The HX Series consists of compact Hall‑effect current sensors designed for the electronic measurement of DC, AC, and pulsed small currents ranging from 2 to 50 A, with full galvanic isolation between primary and secondary circuits.
Optimized for industrial applications, HX sensors combine high performance with a small mechanical footprint and competitive cost.
Designed for PCB mounting, HX current sensors require only 2.93 cm² of board space and weigh approximately 8 g, making them well suited for space‑constrained designs. They provide a voltage output with a measuring capability extending up to 3 × Ipn.
The HX Series is available in multiple models and versions, supporting both dual supply (±12 to ±15 V) and single supply (+12 to +15 V) configurations.
Within the range, HX‑P and HX‑NP variants are offered, with the HX‑NP version featuring two insulated primary windings for specific integration needs.
