1. F series connector brief introduction:

The F series micro-circular high-density connector is a split-type push-pull structure. It has a self-locking function after plugging, and a semi-circular positioning piece is used inside to prevent errors. The positioning piece multi-party positioning system prevents the wrong insertion and removal on the same core number, and also has the blind insertion function, which is convenient and quick to use.

This series of connectors features fast insertion, high density, waterproof, small size, blind insertion and high life. It is especially suitable for high-density installations, relatively small space installations, and places where it is difficult to separate by rotation. Can be applied to harsh environments in the field, protection class IP68.Connector assures a reliable connection with corresponding Fischers connector and connector of other companies of the same type making it.

Making it an ideal choice for Medical, Test & Measurement, Research, Communications, Broadcast Connector, Machines, Defense, Robotic, Aerospace, public sector, Information Systems, Motorsport, Miscellaneous applications.

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

2. F series connector description:

  • security of the Push-Pull self-latching system
  • multipole types 2 to 40 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.
