Current Sensors datasheet and documents for CR9380-NPN-M

CR9380-NPN-M

Current Sensors Overview

The CR9380-NPN-M is a split-core current switch designed for AC applications, manufactured by CR Magnetics Inc. It features a 100A detection range with bidirectional polarization and supports frequencies from 50Hz to 400Hz. The device utilizes an NPN transistor output and operates as a self-powered unit. It offers a response time of 100ms for turn-on and 250ms for turn-off. The module is housed in a compact design suitable for panel or DIN rail mounting, providing fully isolated switching capabilities for industrial monitoring.

Current Sensors Feature Summary

Self-powered operation eliminates the need for external supply voltage
Split-core design allows for non-invasive installation around conductors
NPN transistor output provides direct compatibility with PLCs and relays
Fully isolated construction ensures safety and noise immunity

Current Sensors Applications

Industrial machine current monitoring
PLC input signal generation
Electrical panel status indication
Motor circuit protection systems

Current Sensors Procurement Notes

Verify that the application current exceeds the 350mA full-open threshold to ensure proper output activation. Confirm that the load connected to the NPN output includes necessary clamping diodes for DC circuits or buffer networks for AC circuits to prevent damage. Ensure the conductor size fits within the split-core aperture before ordering.

Current Sensors Selection Notes

Select this model when a self-powered, low-cost switching solution is required for AC currents up to 100A. The NPN output is suitable for sinking current to ground. Consider the CR9380-ACA-M variant if SCR output is preferred for AC loads. This component is not suitable for continuous currents below 350mA due to potential output failure.

Current Sensors Part Context

This part belongs to the CR9380 series of current switches from CR Magnetics Inc. The series is characterized by fixed trip points and low cost. The -NPN-M suffix specifically denotes the NPN transistor output configuration and the modular split-core form factor, distinguishing it from other variants like the ACA (SCR) version.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should verify pinout and electrical specifications against existing designs before considering alternative manufacturers.
