Project Description

1. B series connector brief introduction:

B Series offers a modular, ergonomic, rugged and reliable circular multipole connector for applications needing quick and secure Push-Pull latching. Making it an ideal choice for Medical, Test & Measurement, ResearchCommunications, Broadcast Connector, Machines, Defense, RoboticAerospace, public sector, Information Systems, MotorsportMiscellaneous applications. The modular insert configurations include a wide range of high-density multi-pole contacts. Contacts can be of solder type, PCB straight or PCB elbow type of contact.

B-Series ranges from 00 to 3B size, B-Series allows for a higher contact density while preventing mismating.

These high quality Spring connectors are CE certificated, ISO9001(2015) and cable assembly can be provided. it can cross Lemo variations and sizes.

2. B series connector description:

  • security of the Push-Pull self-latching system
  • multipole types 2-26 contacts
  • solder, print contacts (straight or elbow)
  • high packing density for space savings
  • multiple key options to avoid cross mating of similar connectors
  • keying system («G» key standard) for connector alignment
  • 360° screening for full EMC shielding.

      If you have purchased Lemo connector and know the original model, please tell us. We will directly offer you our corresponding one.

      If you don’t know much about the connector, please make choose according the following factors:

      1 the use of the environment, indoors or outdoors, waterproof or not;

      2 the panel hole size, to select the appropriate plug and socket of right dimension;

      3 the current-voltage, number of contact and the realization of the function, to determine the contact(cores) ;

      4 select the appropriate clamp diameter and sheath;

      5 according to the actual needs of different angles of the keys, to determine the keying (the standard keys as G).
