Honeywell CSNF161 Current Sensor

The CSN Series closed loop current sensors are based on Magnetoresistive or Hall effect principles, with a null balance method to measure AC, DC, and impulse currents up to 1200 amps. These sensors feature high overload capacity, rapid response, excellent electrical isolation, and compact size, making them ideal for variable speed drives, overcurrent protection, ground fault detection, robotic systems, UPS, and automotive battery management. They operate within a temperature range of -40°C to 85°C and have a high precision of ±0.5%. The sensor outputs a current proportional to the primary current, and features a 1000-turn coil with glass-filled PBT housing for durability.
