1. U series connector brief introduction:

The U series connector is a push-pull self-locking connector that combines the multi-key position and multi-positioning structure derived from the B-series positioning pin structure and the F-series semi-circular positioning structure. The connector is mainly used for low-frequency signal transmission in electronic equipment. Easy operation, good shielding effect, good sealing, three-key positioning and semi-circular positioning double anti-misinsertion, solid shell, anti-electromagnetic interference, good environmental resistance, long service life and other characteristics. Widely used in medical machinery, communication systems, computers, small communications and other equipment. Making it an ideal choice for Medical, Test & Measurement, ResearchCommunications, Broadcast Connector, Machines, Defense, RoboticAerospace, public sector, Information Systems, MotorsportMiscellaneous applications.

2. U series connector description:

  • security of the Push-Pull self-latching system
  • multipole types 2 to 19 contacts
  • Easy mating, can be blind-mated (guiding mechanism ensures precise alignment)
  • Increased equipment life span (guiding mechanism optimally protects the contacts)
  • Robust and shock resistant (designs ideal for equipment used in the field)
  • watertight connection (IP 68/IP 66),waterproof and sandproof;
  • solder, print (straight or elbow) contacts
  • high packing density for space savings
  • 360°screening for full EMC shielding.
