Micro Coaxial Cable 256X42AWG OD=8.5mm PVC Sheath Medical B Ultrasound Probe Cable Transducer Cable

Engineering & Procurement Considerations

What Engineers Should Consider When Selecting a 256-Core Micro Coaxial Ultrasound Probe Cable

A high-density micro coaxial ultrasound probe cable connects an ultrasound transducer or probe assembly with the supporting diagnostic equipment. When the cable contains a very high number of individual signal channels, engineering teams need to balance core density, fine-gauge conductors, cable diameter, electrical consistency, shielding, flexibility and connector integration.

This configuration is defined by 256 micro coaxial channels, 42AWG conductors and an 8.5mm outer diameter, making it a high-density cable solution for B-ultrasound and medical transducer applications.

Product Configuration

The 256C + 42AWG + 8.5mm OD combination should remain clearly visible as the main technical identity of the product.

Key Engineering Requirements

256-Core Configuration Considerations

The 256C configuration is one of the most important engineering entities for this product.

Before production, customers should define the function and assignment of all 256 channels.

Potential circuit groups may include:

• Ultrasound signal channels

• Power

• Ground / return

• Reference connections

• Shield connections

• Control lines

• Auxiliary channels

For a cable with 256 individual coaxial channels, a complete cable drawing + wiring diagram + connector pinout is strongly recommended.

The supplier should not infer the channel allocation from core count alone.

42AWG Fine-Gauge Conductor Considerations

The 42AWG conductor size allows a large number of conductors to be integrated into a relatively controlled cable diameter.

Customers should specify:

• Conductor material

• Plating

• AWG

• Stranding structure

• Insulation

• Electrical requirements

• Flexibility requirements

Fine-gauge conductor processing becomes increasingly important as the channel count increases because variation in individual conductors can accumulate across the complete cable structure.

8.5mm Outer Diameter Considerations

The published configuration specifies an 8.5mm OD.

Engineering teams should confirm:

• Target OD

• Maximum allowable OD

• OD tolerance

• Probe routing clearance

• Handle entry dimensions

• Connector entry dimensions

• Required bending radius

• Strain relief

A high-core-count cable requires careful dimensional control because the final OD depends on the coaxial structure, conductor geometry, shielding and PVC sheath.

Micro Coaxial Construction

The micro coaxial architecture is particularly important for this 256-channel ultrasound cable.

Engineers should define:

• Number of coaxial channels

• Inner conductor size

• Dielectric construction

• Individual shielding

• Shield material

• Shield termination

• Overall cable arrangement

• Finished OD

For high-density ultrasound systems, the coaxial construction should be evaluated for both electrical performance and manufacturability.

Signal Integrity Considerations

For a 256-channel ultrasound cable, signal integrity should be considered at both the individual channel and complete cable level.

Relevant parameters may include:

• Conductor geometry

• Capacitance

• Impedance, where specified

• Cable length

• Dielectric structure

• Shielding

• Channel-to-channel consistency

• Connector termination

• Grounding

Where the customer's ultrasound system has defined electrical acceptance criteria, these should be included in the cable drawing or RFQ.

Channel-to-Channel Consistency

High-core-count cables introduce an additional procurement concern: consistency among hundreds of individual signal paths.

Customers may need to define:

• Electrical tolerance between channels

• Capacitance consistency

• Signal characteristics

• Shield continuity

• Conductor resistance

• Insulation performance

• Dimensional consistency

For 256C configurations, production quality should be evaluated across the complete channel population rather than from a small number of randomly selected conductors.

Shielding and EMI Considerations

The micro coaxial construction provides individual shielding around the signal paths.

Customers should clarify:

• Individual shield material

• Shield coverage

• Grounding configuration

• Shield termination

• Overall shielding requirements

• Channel isolation requirements

• Connector-side shield continuity

For dense ultrasound systems, shielding and grounding should be considered together with capacitance and signal integrity.

PVC Sheath Considerations

The product configuration uses a PVC sheath.

Engineering teams should specify:

• PVC material requirement

• Flexibility

• Surface characteristics

• Cleaning conditions

• Mechanical handling

• Operating environment

• Cable OD

• Color

• Strain relief

The outer sheath should be evaluated together with the internal micro coaxial structure because the sheath affects the final cable dimensions and mechanical characteristics.

Flexibility and Probe Routing

Ultrasound probe cables are often handled repeatedly during examination.

Customers should define:

• Static or dynamic bending

• Minimum bending radius

• Repeated movement

• Probe handling

• Cable routing

• Connector exit direction

• Strain relief

• Expected service conditions

For a 256-channel cable, the flexibility requirement should be evaluated carefully because the very high channel density can affect the overall mechanical behavior.

Connector and Termination Considerations

The connector and termination are critical for a 256C ultrasound cable.

Customers should provide:

• Connector manufacturer

• Connector series

• Part number

• Contact count

• Pin assignment

• Connector orientation

• Mating interface

• Termination method

• Shield termination

• Strain relief

For such a high-channel-count cable, a complete termination drawing is strongly recommended.

Key Procurement Parameters

When sourcing a 256C 42AWG micro coaxial B-ultrasound cable, procurement teams should confirm:

OEM Customization

HOTTEN supports customized micro coaxial ultrasound probe cable development according to customer drawings and electrical requirements.

Customization may include:

• Core / coaxial count

• AWG

• Conductor material

• Micro coaxial geometry

• Shielding

• Cable diameter

• PVC or other outer sheath

• Cable length

• Connector configuration

• Pin assignment

• Termination

• Prototype samples

• Mass-production configuration

For OEM projects, the final construction should be developed around the customer's ultrasound transducer, connector architecture and mechanical routing requirements.

Supplier Evaluation Checklist

When evaluating a supplier for a 256-core micro coaxial ultrasound cable, procurement teams should consider:

① Ultra-High-Core-Count Capability
Can the supplier consistently manufacture and control 256 coaxial signal paths?

② Fine-Gauge Processing
Can the supplier reliably process 42AWG conductors across hundreds of channels?

③ Channel-to-Channel Consistency
Can the supplier maintain consistent electrical and dimensional performance across the complete cable?

④ Dimensional Control
Can the supplier consistently achieve the required 8.5mm OD and tolerance?

⑤ Micro-Coaxial Manufacturing Capability
Can the supplier maintain coaxial geometry and shielding across a very high channel count?

⑥ High-Density Connector Assembly
Can the supplier accurately terminate the required 256-channel interface?

⑦ Prototype-to-Mass-Production Support
Can the supplier support engineering samples and recurring production?

Recommended RFQ Information

For faster engineering evaluation and quotation, customers are recommended to provide:

• Ultrasound probe / transducer application

• 256-core requirement

• 42AWG conductor requirement

• Conductor material

• Micro coaxial construction drawing

• Shielding requirements

• Target 8.5mm OD

• OD tolerance

• PVC sheath requirement

• Cable length

• Flexibility / bending requirement

• Capacitance requirements

• Impedance requirements, where applicable

• Channel assignment

• Connector part numbers

• Pinout

• Termination drawing

• Prototype quantity

• Expected production volume

• Required testing

For this product, the most important RFQ combination is:

256C + 42AWG + 8.5mm OD + Micro Coaxial + PVC + Electrical Requirements + Connector + 256-Channel Pinout
