SMB / SMC / SMS Series
The SMB, SMC. SMS series of coaxial connectors are smaller than the SMA series and have many applications within electronic equipments and the interconnection of sub assemblies. The three versions are the same basic size and design but use three different coupling methods. SMB uses a snap-on coupling that uses a "ring in a groove" method for positive retention. Frequency up to 4GHz.. SMC uses a threaded coupling, that gives it improved performance and allows use up to 10GHz with low VSWR. SMS uses a slide-on coupling that makes it suitable for rack and panel types of installation. The performance of this is similar to the SMB version with a limit of about 4GHz. Unlike most of the other conventional ranges, the female contact is used in the plug body while the male contact is used in the jacks and receptacles on all versions. They are used with cables in the small diameter range of 1.8mm to 2.8mm. Semi-rigid, conformable and flexible. Features -50ohm impedance -Captive contacts -Plating: Centre contacts gold. Bodies’ gold or nickel or white bronze Cable termination types -Solder contact / solder outer (semi rigid) -Crimp contact / solder outer (semi rigid) -Solder contact / crimp outer -Crimp contact / clamp outer -Crimp contact / crimp outer -All clamp versions use pressure sleeve clamp · Straight and angle cable entries · Bulkhead units with front or rear mounting · Press-fit fixed units available · PCB mount versions straight & angle in standard dip solder, press-fit & straight & edge mount versions · Adaptors in series, free versions only · Terminations with female contact
