SCT-0400-001 is listed in the Current Sensors range at ChipApex. The manufacturer field lists Magnelab, Inc.. Its product description is 0.4" SPLIT-CORE CT 1A:333MV. Review the specifications below when checking this part for your BOM.
The SCT-0400-001 is a unidirectional current sensor module manufactured by Magnelab, Inc. It features a split-core design with a 0.4-inch aperture for single-pass through installation. The device is rated for a primary current of 1A and provides an output signal of 333mV.
Verify the exact part number suffix to confirm the specific current rating and output voltage characteristics. Ensure the application requires a unidirectional sensor, as this model does not support bidirectional flow. Confirm that the conductor diameter fits within the 0.4-inch split-core aperture before procurement.
Select this component when a low-profile, split-core solution is needed for 1A AC current monitoring. The 333mV output is suitable for direct interfacing with standard analog-to-digital converters or amplifier stages. Consider the unidirectional limitation if reverse current flow detection is required.
This part belongs to the SCT-0400 series of open-loop current sensors from Magnelab. The series includes variants with different current ratings, such as the 5A version (SCT-0400-005), sharing the same physical form factor and split-core architecture but differing in electrical specifications.
Direct replacements must match the 1A rating and 333mV output. Verify that substitute models maintain the 0.4-inch aperture size and unidirectional functionality to ensure mechanical and electrical compatibility in the existing assembly.
