parts view rectangular connector ALFA'R B-SME series

Rectangular Multi-Contact connectors, B-SME and B-SCT series, are based on the same principle as the rack connectors of the B-SMF series, but unlike those, these are mounted on robust aluminum housings and have got an useful toggle clamp. It can stack modules of 2, 3, 5 and 8 contacts.


The modules are inserted in a suitable frame and stacked in a robust and reliable way. They are configured according to your needs. Two sizes of connectors are available: 35.75 mm and 82.5 mm on connection interface, corresponding to 13 umb and 30 umb respectively (MonoBlock Units, 1 umb = 2.75 mm)

Contacts can be of different types depending on the nature of the contacts what they cotain:


  • Electrical: They can be male, female or mix of them in the same monoblock unit. The section of the contacts is defined by the number of elements of each monoblock. They can be 2, 3, 5 or 8 with a nominal current per contact of 7.5 A up to 25 A. And with pins for soldering or crimping cable, or soldering in PCB. Also with RJ-45 and USB connectors are available.


  • Coaxial: Supplied in blocks of 2 connectors, which can be male or female and 50 Ω or 75 Ω. The connectors are mountable and removable inside the monobloc module, by extraction tool. Compatible with D sub-coax connectors, DIN 41626 (1.0 / 2.3), …


  • Fiber optic: Supplied in blocks of 2, 3 and 5 connectors


  • Compressed and vacuum: They are presented in blocks of two connectors, which can be male, female or a mixture of them, for tube Ø 4.The combination of some or all of these technologies in a single connector, results in the COMBI-TECH connector.  B-SCT series

MultiContact rectangular MC connectorS

The modules of the rectangular multi-contact connectors are manufactured with thermostable material supporting temperatures of -40ºC to + 120ºC, except the 8-contact module which is manufactured in thermoplastic supporting from -55ºC to + 90ºC. Both with great resistance to impacts.


The central electrical contacts are made of brass with gold plating. Female contacts with contact safety springs, or with the new TSS® system with more than 500,000 guaranteed mating cycles. Through the robust housing a very reliable connector is achieved in very severe environments.


The manufacturing program is very wide, in addition to the two existing sizes of interface width, it is available, panel receptacles or aerial straight and right angle, which can be short or long. The cable outlet is made by means of glands: clamp system from 5 to 32 mm, multi-wired output or for corrugated tube from 10 up to 48 mm.
