Important Usage Notes:
The through-core wire must be single-phase only.
Choose the appropriate model based on the current range of your wire.
This device is an electronic switch—do not use a multimeter to test K1/K2 terminals.
Use a load to verify the status of K1/K2 contacts.
K1/K2 terminals output switch signals only and do not carry voltage or current.
A power supply must be connected in series with the load for proper operation.

FAQs
Q1: Can this sensor directly trigger a PLC or relay?
A1: Yes, the output provides a switch signal that is compatible with PLC digital inputs, relays, and contactors.
Q2: What’s the difference between NO and NC types?
A2: NO (Normally Open) sends a signal when the current exceeds the set threshold. NC (Normally Closed) stops the signal under the same condition.
Q3: Is the current threshold adjustable?
A3: Yes, the sensing current threshold can be easily adjusted using the built-in potentiometer to match various load requirements.
