21SX39-T2 Frequently Asked Questions (FAQ)

  • The recommended mounting orientation is with the sensor axis vertical and the connector down. This orientation helps to prevent moisture from entering the sensor.

  • To minimize EMI/RFI interference, use a shielded cable, keep the sensor away from high-frequency sources, and use a ferrite bead or EMI filter on the signal lines.

  • The maximum recommended cable length is 10 meters (33 feet) to minimize signal attenuation and noise pickup.

  • No, the 21SX39-T2 is not designed for use in vacuum or high-pressure environments. It is intended for use in ambient atmospheric conditions.

  • The 21SX39-T2 is factory-calibrated and does not require user calibration. However, if you need to perform a system-level calibration, consult the datasheet and application notes for guidance.
