Bard part 8301-111BX is an OEM RDS sensor with a 6-pin Modbus connection used on compatible Bard wall mounted HVAC equipment to communicate sensor data to the unit controls for stable operation and accurate monitoring. When an RDS or communication related fault points to the sensor or its wiring, replacing with the correct Bard 8301-111BX helps restore proper data reporting and system responsiveness without guesswork on fit or connector style. Verify compatibility by matching the part number to your Bard model and control configuration before ordering, and inspect the harness and plug condition during installation to prevent repeat communication issues.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
