CR9380-PNP-M

Current Sensors Overview

The CR9380-PNP-M is a split-core current switch manufactured by CR Magnetics Inc. designed for bidirectional AC current monitoring. It features a single channel with a detection capacity of 100A and utilizes a PNP transistor output configuration. The module operates within a standard packaging format and supports DIN rail or panel mounting. This component provides electrical isolation and reverse polarity protection, functioning as a self-powered device suitable for industrial applications requiring reliable current status indication.

Current Sensors Feature Summary

• Split-core design allows for non-intrusive installation around conductors
• Bidirectional sensing capability for accurate AC current monitoring
• PNP transistor output enables direct connection to PLCs or relays
• Self-powered operation eliminates the need for external supply voltage

Current Sensors Applications

• Industrial machinery current monitoring
• PLC input signal generation
• Electrical panel status indication
• Motor control circuit supervision

Current Sensors Procurement Notes

Verify that the specific application requires a PNP output type, as NPN variants exist within the same series. Confirm the load current exceeds the minimum threshold of 350 mA to ensure proper switching performance. Check if the system requires a clamp diode for DC loads or a snubber network for AC inductive loads when interfacing with mechanical relays. Ensure the conductor size fits within the split-core aperture specifications.

Current Sensors Selection Notes

Select this model when bidirectional AC current detection is required without an external power source. The PNP output is ideal for sinking current to a controller input. Consider the CR9380-NPN-M variant if sourcing current from the controller is necessary. Evaluate the 100A rating against peak load requirements to prevent saturation or inaccurate triggering during transient events.

Current Sensors Part Context

This component belongs to the CR9380 series of low-cost, self-powered current switches. The series is engineered for simple on/off current indication rather than precise analog measurement. It serves as a robust interface between high-current circuits and low-voltage control logic, offering galvanic isolation to protect sensitive downstream electronics from high-voltage faults.

Current Sensors Replacement Considerations

The CR9380-NPN-M is a confirmed substitute within the same product family, differing only in output polarity. No other cross-model replacements are documented in public sources.
