Before writing off a damaged Edan C422UB, compare its symptoms against the failure modes below. Many lens, cable and connector faults on this probe class are economically repairable.
| Manufacturer | Edan |
|---|---|
| Model | C422UB |
| Probe type | Micro-Convex array |
| Frequency reference | 2.7 MHz |
| Typical applications | Abdominal, Cardiac |
| Compatible systems | Edan U50 Prime, Edan U60 |
| Source record | The Ultrasound Source product record |
In service the C422UB is most often found on Edan U50 Prime, Edan U60. Console-side settings and module revisions still vary, so the exact system build is part of any assessment.
Micro-convex heads like the C422UB serve pediatric and tight-window work; the small lens face wears fast under pressure and the fine cable bundles are vulnerable at the strain relief.
Common failure modes for the C422UB
Match what you are seeing against the table below. The right-hand column reflects how faults of this kind typically assess – the actual verdict always depends on the individual probe.
| What you see | Likely cause | Typically repairable? |
|---|---|---|
| Split seams or impact marks on the probe body | Impact damage; housing can usually be replaced or resealed | Usually repairable |
| Depth performance clearly below what this probe used to deliver | Reduced acoustic output from element ageing or a delaminating lens | Case by case |
| Bent, broken or corroded connector pins | Connector damage from forced insertion or drops | Usually repairable |
| Air pockets or peeling visible on the acoustic lens | Lens delamination from the acoustic stack | Usually repairable |
| Whole regions of the image blank across the array width | Widespread element or acoustic stack failure | Usually not economical |
| Connector lock broken or hardware missing | Broken locking mechanics on the connector housing | Usually repairable |
| Strain relief pulling away from the cable or gone rigid | Flex fatigue where the cable meets the probe or connector | Usually repairable |
Check these before you ship the probe
- Compare penetration and uniformity against a known-good probe on the same preset.
- Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.
- Examine the connector for bent or corroded pins, cracks and a working locking mechanism.
- Run the system’s built-in probe test or element check if your console provides one.
- Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
Repair, exchange or replace — which applies to your C422UB
For the C422UB, think in terms of damage depth: surface and cable-level faults are usually repairable at a fraction of replacement cost; acoustic stack failures are evaluated case by case; extensive element loss generally means replacement. Send the symptoms and photos first – that determines the path before anything ships.
What we need to quote your C422UB repair
- A clear photo of the complete manufacturer and model label on the probe
- A description of the fault: what you see on screen and when it started
- The ultrasound system (console) the probe is used with
- Screenshots or photos of the image problem, if the fault is visual
- Photos of any physical damage – lens, housing, cable or connector
