HSTS016L 100A Split-Core Hall Effect Current Sensor with 2.5V Output

The HSTS016L is a split-core Hall effect current sensor designed for non-contact measurement of AC and DC currents up to 100A. Its ferromagnetic core concentrates the magnetic field generated by the conductor, and an internal Hall element converts that field into a proportional analog voltage. The sensor provides a output of 2.5V ± 0.625V from a single +5V DC supply, making it directly compatible with microcontroller ADCs and industrial control systems without additional signal conditioning. Because the core is split, the sensor can be clamped around an existing cable or busbar without disconnecting the circuit, which simplifies installation in retrofits and live panels. This 100A hall sensor offers galvanic isolation of 2.5kV for one minute at 50Hz, protecting downstream electronics from overvoltage and noise. The measurement bandwidth extends to DC, so both static and dynamic currents can be monitored with a typical accuracy of 1% and linearity better than 0.1%. Housed in UL94-V0 flame-retardant material, the HSTS016L current sensor operates from -10°C to +70°C and is suitable for motor control, switching power supplies, UPS systems, welding equipment, and energy management installations. Whether used for overload protection, battery monitoring, or renewable energy metering, this split core current sensor provides a practical combination of isolation, bidirectional measurement, and straightforward analog interfacing.
