SMA series
SMA series
SMA series (’ A’ stands for the first version) which was produced in the 60s of last century, are super miniature type connectors, and connect with thread. 50Ω SMA series are semi-precise super miniature RF coaxial connector, with outstanding electrical specification and works at a frequency as high as 18 GHZ. SMA connector has a small and exquisite, solid and durable feature, and a good interchangeability. With years of application and continuous research, SMA series has become the ones with most complete categories, most types and models and most widely used. Its application ranges: base; cable accessories; elements; apparatus and instruments; MIL/Space; computer system; process control; postal communication, etc. We provide all types and models of products for our customers.
Measure up to standards: GJB681, SJ50681, SJ50976
MIL-C-39012
IEC60169-15
CECC 22210/22211
In demand of our customers, we have designed and developed the following SMA series connectors:
- Semi-rigid, semi-flexible coaxial cable plug and receptacle (compatible for .085 and . 141 semi-rigid, semi-flexible coaxial cable)
- Flexible cable plug and receptacle ( for all kinds of SYV, SFF, RG flexible cable)
- micro-strip receptacle ( flange mount, applied to microwave system and transition from coaxial cable to micro-strip)
- On-spot replaceable micro-strip receptacle (flange mount , applied to circumstances replacement is needed)
- Strip type end receptacle (flange mount, apply to the transition from coaxial cable to micro-strip cable, strip-shape cable and printed substrate)
- Slotting end receptacle (flange mount, apply to the transition from coaxial cable to suspending micro-strip)
- Straight end receptacle (flange mount, apply to the transition from coaxial cable to micro-strip cable, strip-shape cable printed substrate and wave guide)
- Panel receptacle (flange mount, bulkhead mount, terminal type: inner conductor rear welding, apply to the transition from coaxial cable to micro-strip cable, strip-shape cable and printed substrate)
- Air-tightness micro-strip receptacle (flange mount, bulkhead mount, panel thread mount and apply to the circumstances that air-tightness is needed)
- Printed circuit board receptacle (4-pin welding mount, edge mount, apply to the transition from coaxial cable to printed substrate)
*: small size flange (9.5×9.5) is available, specially fit for the miniaturization of the system and device.
