SMA-J straight crimp RF connector elbow male coaxial plug SMA male antenna crimp terminal straight combo connector Micro Coaxial Cable Crimp RF Connector SMA elbow adapter

Product Description

SMA-J straight through crimp plug and SMA-JW 90° right-angle elbow crimp plug, covering all thin micro coaxial wiring scenarios for wireless equipment.

Outer shell adopts solid brass matte nickel plating for wear and corrosion resistance; central contact pin, elbow transition block and crimp ferrule use full hard gold plating to reduce contact resistance and avoid oxidation signal drift after long-term equipment operation. The crimp end is designed with diamond knurled texture, which increases clamping force when crimping RG174 / RG316 ultra-thin coaxial shielding braid, realizing 360° complete shielding continuity and suppressing EMI interference inside equipment.

Built-in PTFE high-temperature stable dielectric core, stable impedance within DC~6GHz frequency band, no signal reflection loss caused by temperature alternation. The right-angle SMA-JW model solves the space limitation of narrow PCB cabinets and hidden antenna wiring, avoiding sharp cable bending fracture.

Widely matched with car GPS antennas, wireless router built-in modules, Bluetooth testing equipment, portable remote control signal transceivers. Support customized full gold-plated shell, lengthened crimp section and finished RF jumper production; all raw materials comply with RoHS low-halogen environmental standards.

Advantages

Dual Straight + Elbow Complete Series Covers All Thin Coax Wiring Scenarios (Core Advantage)
SMA-J straight and SMA-JW 90° elbow two specifications are matched at the same time, solving linear panel wiring and narrow space folded hidden wiring demands of wireless equipment, one series meets router, GPS, test instrument multi-product design, simplify supplier inventory management.
90° Elbow SMA-JW Solves Narrow Space Cable Bending Breakage Problem
Ordinary straight connectors need sharp 90° bending of thin coax inside narrow cabinets, which easily leads to internal core wire fatigue fracture; the integrated L-shaped elbow directly changes the cable outlet direction, protect RG174/RG316 micro thin wire service life.
Knurled Gold-Plated Crimp Ferrule Stable Shielding Anti-EMI Interference
Diamond texture crimp sleeve increases friction with shielding braid, will not slip after long-term equipment vibration; 360° full gold-plated shielding layer effectively filter frequency converter and power supply electromagnetic noise, prevent GPS positioning drift and WiFi signal weakening.
Mixed Nickel-Gold Plating Balance Cost And High-Frequency Performance
Outer shell adopts low-cost wear-resistant nickel plating, key conductive contact parts use thick gold plating to ensure signal stability, avoid the high cost of full gold-plated connectors while guaranteeing long-term anti-oxidation performance.
DC~6GHz Broadband Compatible With All Civil Wireless Communication Signals
Covers GPS full band, 2.4G/5.8G WiFi, Bluetooth, remote control UHF frequency band, widely applicable to consumer electronics, industrial IoT wireless modules, laboratory miniature test equipment.
One-Stop Custom Thin Coax RF Jumper Service
Support small batch prototype sampling and mass OEM production, can be processed into finished straight/elbow SMA antenna extension cables with customized lengths of RG174/RG316 micro coax for wireless module factories.

FAQ

Q1: What is the difference between SMA-J straight and SMA-JW elbow connectors in usage?

A:SMA-J straight: Cable extends along the same axis as SMA thread, used for equipment panel linear outward antenna wiring, short signal path, minimum attenuation;

SMA-JW elbow: Cable outlet is perpendicular to the thread axis, used for narrow PCB cabinet, side wall hidden wiring, avoid sharp bending of thin coaxial wire inside limited space;

The two cannot replace each other due to different mechanical space layout demands.

Q2: Can this SMA-J/JW crimp connector use thick RG58 coaxial cable?

A: No. The inner diameter of the knurled crimp ferrule is designed for ultra-thin RG174/RG316 micro coax, the shielding braid of thick RG58 cannot be fully clamped, which will cause poor shielding and serious signal leakage. If you need RG58 matching, select SMA-J-5 large crimp type connector.

Q3: Is SMA-JW elbow easy to cause high-frequency signal reflection loss?

A: No. The internal transition part of the elbow is integral gold-plated smooth right-angle block, optimized impedance matching design, VSWR ≤1.40 up to 6GHz, no obvious signal surge or attenuation compared with straight SMA-J.

Q4: What is the service life of the gold-plated contact inside the connector?

A: Hard gold plating thickness ≥0.6μm, can withstand ≥500 times repeated plugging and unplugging, long-term indoor equipment operation will not oxidize and blacken, contact resistance remains stable.
