HOYS 100-S/SP33-1106

Current Sensors Overview

The HOYS 100-S/SP33-1106 is an open-loop Hall effect current sensor designed for AC, DC, and pulse current measurements. It features a nominal primary current of 100 A and provides a ratiometric voltage output. The device operates on a single supply of +3.3 V or +5 V, with a bandwidth extending from DC to 250 kHz at the -3 dB point. Key electrical specifications include a sensitivity of 4.6 mV/A, linearity of ±0.75%, and a short response time of 3.5 µs. The unit supports panel mounting via a large aperture bus bar interface.

Current Sensors Procurement Notes

Verify the specific suffix SP33-1106 corresponds to the required +3.3 V supply voltage and ratiometric output configuration. Confirm that the 100 A nominal rating aligns with the peak load requirements of the target application. Ensure compatibility with the specified operating temperature range of -40°C to +105°C for the intended environment.

Current Sensors Selection Notes

Select this model when precise measurement of bidirectional currents up to 100 A is required in space-constrained designs. The low offset and gain drift characteristics make it suitable for applications demanding high stability. Consider the 2.5 x Ipn overcurrent detection capability if protection against transient spikes is necessary within the system architecture.

Current Sensors Part Context

This component belongs to the HOxx-S series of high-performance, cost-effective current transducers by LEM USA Inc. The series offers various nominal current ratings including 50 A, 100 A, 150 A, 200 A, 240 A, and 250 A RMS. All models share similar architectural features such as bus bar mounting and wide bandwidth capabilities.

Current Sensors Replacement Considerations

Direct substitutes within the same family include HO 150-S/SP33-1106 (150 A) and HO 250-S/SP33-1106 (250 A). These alternatives maintain identical form factors and electrical interfaces but differ in nominal current capacity. Verify that the higher ratings do not compromise sensitivity requirements for lower current signals.
