CR9380-PNP

Current Sensors Overview

The CR9380-PNP is a low-cost, self-powered current switch designed for on-off indication of current flow. It features a fixed set-point with a maximum switching capacity of 100A and operates as a bidirectional module with a single pass-through design. The unit utilizes a split-core configuration with a 0.40-inch inner diameter, allowing for non-mounting installation. It provides a PNP output transistor suitable for switching DC applications up to 30VDC. The device supports frequency ranges from 50Hz to 400Hz and includes reverse output polarity protection.

Current Sensors Feature Summary

• Self-powered operation eliminates the need for external supply voltage
• Bidirectional sensing capability for versatile current monitoring
• Split-core design enables easy installation without circuit interruption
• Fully isolated output with reverse polarity protection

Current Sensors Applications

• Direct connection to PLCs for current status monitoring
• Switching electromechanical relays in industrial control systems
• Continuous work current indication above rated thresholds
• AC/DC current flow detection in machinery

Current Sensors Procurement Notes

Verify that the specific part number matches the required output configuration, as the series offers both NPN and PNP variants. Confirm that the application current exceeds the 350 mA full-on level to ensure proper output activation. For direct connections to inductive loads such as electromechanical relays, ensure appropriate external components like clamping diodes for DC or snubber networks for AC are provided by the customer to protect the device.

Current Sensors Selection Notes

Select this model when a fixed set-point current switch is required for simple on-off indication rather than continuous measurement. Ensure the load current remains consistently above the 350 mA threshold to maintain output reliability. Consider the split-core form factor if wiring modifications are not feasible. Verify compatibility with the target controller input type, specifically confirming the PNP logic level matches the system requirements.

Current Sensors Part Context

The CR9380 series represents a line of cost-effective current switches manufactured by CR Magnetics Inc. These devices are engineered for straightforward integration into systems requiring basic current presence detection. The series distinguishes itself through self-powered functionality and robust isolation features, making it suitable for environments where complex signal conditioning is unnecessary.

Current Sensors Replacement Considerations

CR9380-PNP-M serves as a variant within the same product family. Cross-reference pinout and mounting specifications before substitution. Ensure the replacement maintains the PNP output configuration and identical 100A rating to preserve system functionality.
