Frequently Asked Questions

What is the operating voltage range for the SEC345 sensor?

The SEC345 electronic compass sensor operates from a wide 5 to 12 VDC power supply. This range accommodates common industrial voltage levels and includes protection against reverse polarity connection, ensuring stable performance in varied electrical environments.

How do I communicate with the SEC345 sensor?

The sensor provides three selectable serial communication interfaces: RS485 (supporting Modbus protocol for daisy-chaining), RS232 (for direct PC connection), and TTL (3.3V/5V logic for microcontrollers). The interface is typically selected via a configuration command or hardware Jumper, as detailed in the product datasheet.

Does the sensor require calibration for magnetic interference?

Yes, the SEC345 features integrated hard and soft magnetic compensation. The hard magnetic compensation corrects for permanent magnetic distortions from nearby ferrous materials, while soft magnetic compensation handles induced fields. A one-time calibration procedure is recommended during installation in its final operational environment for optimal accuracy.

What is the sensor's accuracy and resolution for heading measurement?

The sensor offers a heading accuracy of ±1° (root mean square) and a resolution of 0.1° over its full 0° to 360° range. For tilt (pitch and roll) measurements within a ±40° range, the accuracy is 0.1°, providing high-precision 3D orientation data.

Is this sensor suitable for outdoor or harsh environments?

Absolutely. With an operating temperature range of -40°C to +85°C and a robust, shielded metal housing, the SEC345 is engineered for demanding conditions. It is ideal for applications in marine navigation, unmanned vehicles, and industrial automation where temperature extremes and electromagnetic interference are concerns.
