The Aloka EP494800 Probe Connector Board Assembly is a critical internal module within the Aloka ProSound Alpha 10 (and Pro) ultrasound platforms, responsible for interfacing the multiple ultrasound probes (linear, convex, phased array, etc.) with the system’s electronics. When the system is in use, probes are inserted into the machine’s connectors; this board handles the physical connection, transducer identification, signal routing, and high-voltage switching required for accurate ultrasound transmissions and receptions. Because of the precision and complexity of ultrasound systems, a reliable probe connector board is essential to maintain image quality, ensure safe operation, and support the wide variety of probes used in clinical practice.

From a maintenance and service perspective, this board is typically found in the service parts catalogues and is used when the original board has failed, or when upgrading/repairing the probe interface subsystem. Given its role, it must meet specific electrical, mechanical and signal-integrity requirements: low noise signal pathways, robust connector interfaces, proper shielding, and compatibility with the machine’s firmware and probe firmware/ID systems. The fact that many listings note it was “removed from system/ unit” highlights that it is normally not sold as a standalone spare by the original manufacturer widely, but rather as a spare or replacement from used/ refurbished systems.

In a clinical ultrasound environment using the Aloka ProSound Alpha 10, having a functioning probe connector board such as the EP494800 ensures that probes can be swapped in and out seamlessly, the machine can automatically identify the connected probe, and the imaging chain remains intact. This contributes to minimal downtime, consistent image performance, and flexible probe usage (for example switching between abdominal, cardiac, vascular, and TEE probes). For service engineers and biomedical maintenance teams, this part offers a cost-effective way to restore full probe connectivity functionality without replacing the entire ultrasound system or major subsystem.

Subcomponent or Part Removed from System/Unit (PART):

This medical equipment item is a subcomponent or part that has been extracted from a larger system or unit. It is intended for use as a replacement part or for integration into another system. Its condition may vary, but it has been removed with care to preserve its functionality.
