Current Sensors Procurement Notes

Verify that the specific part number matches the required PNP output type and voltage ratings. Confirm compatibility with the target load, such as PLCs or relays, ensuring necessary external components like clamp diodes are provided if connecting to inductive loads. Check datasheet specifications for continuous operating current limits relative to the rated full-on level to ensure proper function.

Current Sensors Selection Notes

Select this model for applications requiring a self-powered current switch with PNP outputs. Ensure the application involves continuous working currents above the rated full-on threshold to guarantee output activation. Verify that the system can accommodate the necessary external circuitry, such as clamp diodes for DC inductive loads, to protect the switching element during operation.
