Description

The BWSENSING SEC385 is a compact, three-axis electronic compass engineered for reliable orientation sensing in demanding environments. It combines a high-resolution magnetic sensor with a MEMS accelerometer to provide full tilt compensation, ensuring accurate heading data even when the sensor is mounted at significant angles. The sensor’s advanced algorithms correct for hard-iron and soft-iron distortions, maintaining precision in the presence of nearby ferrous materials.

Designed for industrial and field deployment, the SEC385 operates across an extended temperature range and is protected against vibration and shock. Its multi-protocol communication capability (configurable for RS485, RS232, or TTL) offers flexible integration with PLCs, data loggers, and custom control systems, providing a robust solution for precise directional measurement.

Key Features

  • Ultra-high heading accuracy of 0.5° RMS under nominal conditions.
  • Full three-axis tilt compensation (±80°) using integrated accelerometer and magnetic sensor fusion.
  • Hard-iron and soft-iron calibration support for uncompromised magnetic accuracy in variable environments.
  • Wide operating temperature range from –40°C to +85°C ensures performance in harsh field conditions.
  • Compact, rugged form factor (60 x 59 x 29 mm) with a weight of approximately 180 grams.
  • Multi-interface output support for RS485, RS232, or TTL levels, configurable for flexible system integration.
  • High resolution of 0.1° (with internal resolution down to 0.01°) for detecting fine heading changes.
  • Robust construction with anti-vibration shock resistance rated up to 2000 g.

Applications

  • Satellite antenna tracking and positioning systems.
  • Marine survey and autonomous surface vessel (ASV) navigation.
  • Vehicle navigation and attitude determination for agricultural and construction machinery.
  • Industrial mechanical control and robotic arm orientation sensing.
  • Precision surveying and mapping equipment.

Frequently Asked Questions

What is the operating voltage range for the SEC385 sensor?

The SEC385 operates from a wide 9V to 36V DC supply, making it directly compatible with standard 12V and 24V industrial vehicle and control system power buses without requiring an additional voltage regulator.

What communication interfaces are supported?

The sensor supports configurable serial communication interfaces, including RS485, RS232, and TTL-level UART. The baud rate is adjustable from 2400 to 115200 bps to match your host controller or PLC.

How does the tilt compensation work, and what is its range?

The sensor integrates a 3-axis accelerometer with the magnetic compass. This fusion allows it to provide accurate heading data even when tilted, with a full compensation range of ±80° from level. The built-in algorithms correct for pitch and roll in real-time.

Is calibration required for accurate readings?

Yes, for optimal performance, a hard-iron and soft-iron calibration should be performed in the final installation environment. This procedure compensates for permanent and induced magnetic distortions from nearby metal structures, ensuring long-term heading accuracy.

What is the sensor's output data rate?

The SEC385 can output updated heading and tilt data at a rate of up to 50 Hz. This high update frequency is suitable for dynamic applications like vehicle navigation and real-time mechanical control systems.
