Article

This document outlines the recommended procedures for the mechanical and electrical integration of the NexBot Safety 341-008 Thermal Camera (SKU: NXB-SNS-341-008). Proper installation is critical for ensuring measurement accuracy, communication stability, and the operational longevity of the sensor in demanding industrial environments.

Mechanical Installation

The NXB-SNS-341-008 is designed for robust performance when correctly mounted. The primary mounting location for this sensor on compatible NexBot articulated and collaborative robots is the J6 joint (end-of-arm tooling flange).

Mounting Procedure:

1. Ensure the robot is powered down and in a safe, stationary position before beginning work.
2. Verify that the mounting surface on the J6 flange or custom bracket is clean, flat, and free of debris.
3. Align the camera's mounting holes with the corresponding holes on the mounting surface. The camera dimensions are 320 x 95 x 95 mm.
4. Use four (4) M6, class 8.8 or higher, corrosion-resistant bolts to secure the camera. The use of split-lock washers is recommended to mitigate loosening from vibration.
5. Tighten the bolts in a cross pattern to ensure even pressure distribution. Use a calibrated torque wrench to apply a final torque of 9 Nm (±1 Nm).
6. Important: Do not overtighten, as this can damage the camera housing. Ensure that the installation does not compromise the camera's IP54 rating. Use sealed fasteners or apply appropriate sealant if the operating environment contains significant dust or moisture.

Cable Routing: Properly route the sensor cable along the robot arm using the provided cable management channels. Leave sufficient slack at each joint, especially near J6, to prevent cable strain or binding during full articulation of the robot arm.

Electrical Connection

The NXB-SNS-341-008 operates on a standard 24VDC power supply and uses an M12 A-coded 4-pin connector for power and IO-Link communication.

Pinout (M12 Male Connector):

• Pin 1 (BN): +24VDC (L+)
• Pin 2 (WH): Not Connected
• Pin 3 (BU): 0V / GND (L-)
• Pin 4 (BK): IO-Link Communication (C/Q)

Connect the sensor to a certified IO-Link Master port. Ensure the power supply is stable and filtered to prevent electrical noise that could affect sensor readings.

IO-Link Integration

Integration with the robot controller or PLC is achieved via the IO-Link protocol. This allows for digital transmission of temperature data, device status, and configuration parameters.

Configuration Steps:

1. Download the latest IODD (IO-Link Device Description) file for the NXB-SNS-341-008 from the NexBot Robotics support portal.
2. Import the IODD file into your IO-Link Master's configuration software (e.g., NexBot Cell Controller Suite, or a third-party equivalent).
3. Connect the camera to the designated port on the IO-Link Master. The Master should automatically detect the device.
4. Using the configuration software, you can access and set device parameters such as emissivity, measurement range, and data averaging filters.
5. Map the process data inputs (PDI) to your control program. The primary process data includes the measured temperature value and device status bits.

Verification

After installation and configuration, perform the following checks:

1. Power Check: Power on the robot system and verify that the camera's status LED indicates normal operation.
2. Communication Check: In your IO-Link configuration tool, confirm that the NXB-SNS-341-008 is present and communicating without errors.
3. Data Validation: Point the camera at an object with a known temperature to verify that the readings are accurate and stable within the specified tolerance. Monitor the live data stream in the controller to ensure data integrity.
