Custom 40 Core 38AWG Micro Coaxial RF Cable Assembly

Product Overview

HOTTEN Custom 40 Core 38AWG Micro Coaxial RF Cable Assembly is designed for compact electronic systems that require multiple shielded signal channels within a limited routing space.

The assembly uses 38AWG micro coaxial conductors arranged in a 40-core configuration. Each coaxial channel consists of a center conductor, dielectric insulation and surrounding shield, providing controlled signal routing and reducing coupling between adjacent channels.

The cable assembly can be manufactured according to the customer's electrical and mechanical requirements, including impedance, conductor gauge, shielding structure, connector type, pin assignment, cable length and cable exit direction.

RF & Signal Performance

Micro coaxial construction is useful when multiple RF or high-speed signal channels must be routed close together.

Individual coaxial shielding provides separation between neighboring signal paths and helps control electromagnetic coupling. For applications requiring defined RF performance, the cable structure can be specified around the required characteristic impedance, attenuation, shielding effectiveness and operating frequency.

The final electrical construction should be selected according to the system's frequency range and connector interface rather than AWG alone.

Typical Applications

• RF communication equipment
• High-density electronic equipment
• Wireless communication systems
• Compact computing equipment
• Camera and imaging electronics
• Test and measurement equipment
• High-speed signal interconnects
• Compact network and communication equipment

Custom Cable Assembly

HOTTEN can manufacture the 40-core micro coaxial assembly according to customer drawings or samples.

Available customization includes:

• Core count
• 38AWG or other fine-gauge conductors
• Characteristic impedance
• Shielding structure
• Cable OD
• Connector manufacturer and part number
• Connector orientation
• Pin assignment
• Cable length
• Cable exit direction
• Jacket material
• Terminal configuration

Engineering & Procurement Considerations

For a 40-core micro coaxial assembly, the connector interface and electrical specification should be confirmed before production.

For RF applications, the RFQ should ideally include the required frequency range, characteristic impedance, attenuation target, connector PN, pinout, cable length and shielding requirement.

For high-density equipment, the mechanical drawing should also define the available routing space, minimum bend radius and connector orientation.

HOTTEN can review customer RFQ drawings, BOMs, connector part numbers and pinout files before prototype production.

Prototype to Mass Production

HOTTEN supports the development process from prototype samples to volume production.

Typical workflow:

Drawing / BOM Review → Engineering Evaluation → Prototype → Electrical & Mechanical Verification → Production Approval → Mass Production

This allows connector fit, cable dimensions, pin assignment and electrical requirements to be verified before larger production quantities are released.

Quality & Compliance

Depending on the project requirements, HOTTEN can provide:

• Continuity testing
• Pin-to-pin verification
• Electrical performance testing
• Connector inspection
• Dimensional inspection
• First Article Inspection (FAI)
• RoHS / REACH compliance
• UL-related material requirements
• Production quality documentation

FAQ

What impedance can this 40-core micro coaxial cable support?
50Ω is a common configuration for RF applications, while the actual impedance can be customized according to the cable construction and system requirements.

Can the connector be customized?
Yes. HOTTEN can assemble the cable using the customer's specified connector manufacturer and part number.

Can the 38AWG conductor be changed?
Yes. Other fine-gauge conductors can be evaluated according to current capacity, signal requirements, cable OD and mechanical constraints.

Can HOTTEN manufacture according to an existing cable sample?
Yes. An existing assembly or technical drawing can be used for engineering evaluation and prototype development.

What information is required for quotation?
The most useful information includes the drawing, BOM, connector PN, pinout, core count, AWG, cable length, impedance, frequency range and estimated quantity.
