SSMC RF Coaxial Connectors For Flexible Cable Manufacturer

Product Introduction:
The SSMC connector is a miniature RF component derived from the SSMB series. Unlike the snap-on coupling of SSMB, SSMC features a threaded interface (typically #6-40 UNS), delivering superior connection reliability while maintaining a compact size. With a characteristic impedance of 50Ω, it is specifically designed for compact electronic systems that demand high vibration resistance and mechanical stability.

Product Features :
Secure threaded coupling: Compared to snap-on connectors, the threaded mechanism effectively prevents accidental disconnection caused by cable pulling or high-frequency vibration, ensuring continuous signal transmission.
Ultra-fine cable compatibility: Optimized for flexible cables such as RG174, RG178, RG316, as well as ultra-thin cables with diameters of 1.13 mm and 1.37 mm.
Excellent electrical performance: Maintains low VSWR and insertion loss across a DC–6 GHz frequency range.
High-reliability materials: Typically constructed with gold-plated brass housing and PTFE dielectric support, ensuring stable operation in extreme temperatures from -55°C to +155°C.

Application Advantages :
High space efficiency: Smaller than standard SMA connectors, enabling higher-density interface layouts on PCBs or equipment panels.
Flexible and intuitive routing: When paired with flexible cables, it allows complex routing and bending within compact enclosures, simplifying hardware design.
Convenient installation and maintenance: Supports standard crimping or soldering termination methods, making it suitable for large-scale automated production.

Typical Applications:
Miniature communication devices: Such as RF jumpers inside portable radios and compact base station modules.
Aerospace and test equipment: Ideal for space-constrained, high-reliability avionics and precision instrumentation.
Wireless networking devices: Widely used in wireless cards, micro sensor nodes, and IoT terminals.

SSMC RF Coaxial Connectors For Flexible Cable Industry knowledge

SSMC RF Coaxial Connectors For Flexible Cable are sub-miniature, snap-on interface connectors designed for high-density RF and microwave signal transmission in space-constrained assemblies. As a compact derivative within the sub-miniature coaxial connector family, SSMC connectors are engineered for quick mating and de-mating without threading, making them suitable for applications requiring frequent connection changes, tight board-to-board spacing, or limited installation clearance. Manufactured for use with flexible cable types such as RG178, RG316, and equivalent small-diameter coaxial cables, SSMC connectors support signal integrity across a wide frequency range while maintaining a low-profile mechanical footprint.

Common Types and Features

  • SSMC Straight Plug/Jack: Standard in-line configuration for direct cable-to-cable or cable-to-board connections.
  • SSMC Right Angle Plug/Jack: Angled body design for applications with limited vertical clearance.
  • SSMC Bulkhead/Panel Mount: Flange or through-hole mounting for chassis and enclosure integration.
  • SSMC PCB Mount: Surface-mount or through-hole terminals for direct circuit board attachment.
  • SSMC Cable Assemblies: Pre-terminated flexible cable configurations for direct plug-in use.

Typical characteristics of this connector series include snap-on coupling mechanism, 50-ohm impedance matching, gold-plated center contacts and outer conductors for stable conductivity, and compact outer diameter suited to miniaturized RF modules. Frequency performance generally extends into the GHz range, subject to specific connector design and cable pairing.

Application Scenarios

Application Area Typical Use Case
Telecommunications Equipment Internal RF signal routing within compact base station and repeater modules
Test and Measurement Instruments Internal wiring for RF test equipment requiring frequent connector cycling
Wireless Communication Modules Board-to-board or board-to-cable RF links in GPS, GSM, and CDMA modules
Aerospace and Defense Electronics High-density interconnection in space-limited avionics and communication systems

Comparison: SSMC vs. Related Sub-Miniature Connectors

Connector Type Coupling Method Typical Size Primary Use Case
SSMC Snap-on Sub-miniature, smaller than SMB High-density, space-limited flexible cable connections
SMB Snap-on Miniature General-purpose RF connections with moderate density requirements
MMCX Snap-on with locking Micro-miniature Applications requiring rotational freedom and secure locking
SMA Threaded Standard sub-miniature Applications requiring secure threaded connection and higher frequency stability

Selection Points

  • Confirm cable type and diameter compatibility (e.g., RG178, RG316) before selecting SSMC connector variants.
  • Determine mounting style based on assembly constraints: straight, right angle, bulkhead, or PCB mount.
  • Verify frequency range and impedance requirements against the specific application's operating parameters.
  • Consider mating cycle requirements, as snap-on designs are suited to frequent connection and disconnection.
  • Evaluate plating and contact material for environmental exposure and long-term conductivity needs.

FAQ

Q: What distinguishes SSMC connectors from SMB connectors?
A: SSMC RF Coaxial Connectors For Flexible Cable are smaller in outer diameter compared to SMB connectors, allowing higher-density placement on boards and in compact housings, while both use a snap-on coupling method.

Q: Are SSMC connectors compatible with all flexible coaxial cables?
A: Compatibility depends on cable diameter and impedance matching; common pairings include RG178 and RG316 type flexible cables, and specific cable selection should align with the connector's crimp or solder specifications.

Q: What frequency range do SSMC connectors typically support?
A: Frequency performance varies by specific design and cable pairing, generally supporting operation into the GHz range for RF and microwave signal transmission.

Q: Can SSMC connectors be customized for specific applications?
A: Customization options may include mounting style, plating material, contact configuration, and cable assembly length, depending on manufacturing capability and application requirements.
