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.
