The CSNK500M-600 is a high-performance closed-loop current sensor from Honeywell's CSN series. It utilizes magnetic balance technology to provide precise measurement of AC, DC, and pulsed currents up to ±1275A.
Two-way measurement
Closed-loop Hall effect current sensor
Features high current sensing capability
The CSNK500M is a current transducer based on the principle of magnetic compensation. It provides electronic measurement of DC, AC or pulsed currents, and their combinations, with galvanic isolation between the primary (high current) and secondary circuits.As a specific variant within the CSNK500M series, the CSNK500M-600 further optimizes industrial installation convenience through its integrated Molex connector, ensuring reliable electrical connectivity even in high-vibration environments. Beyond inheriting the superior linearity and zero-drift suppression of closed-loop magnetic compensation technology, this device features an instantaneous peak measurement range of up to 1275A and microsecond-level response times. These capabilities make it an indispensable component in high-performance variable frequency drives (VFDs), heavy-duty power supplies, and energy management systems, providing precise current feedback for real-time protection and accurate control of power equipment amidst complex electromagnetic interference.

When using the CSNK500M-600, it is critical to ensure a stable supply voltage (typically ±15V) and avoid magnetic saturation by keeping the measured current within the rated range to maintain high linearity. Since this specific model features a Molex connector, ensure secure mating and correct polarity. Additionally, implement proper electromagnetic shielding and heat dissipation to minimize zero-point drift and prevent high-frequency interference from compromising measurement accuracy.
It is a linear current sensor based on the magnetic balance (closed-loop) principle, used for accurate measurement of AC, DC, and pulsed currents.
How to use CSNK500M-600?
Pass the conductor to be measured through the center hole of the sensor; the sensor will output a small current signal proportional to the measured current for the control system to read.
Does CSNK500M-600 require a power supply?
Yes, it typically requires a bipolar DC power supply (e.g., ±15 VDC to ±24 VDC).
What is the output signal type of CSNK500M-600?
It outputs a current signal (mA), which is usually converted into voltage through a measuring resistor.
What is the accuracy of CSNK500M-600?
Due to the closed-loop technology, it offers high accuracy, excellent linearity, and low temperature drift.
