Project Description

DFN Free Socket, with arc-shape metal guides, collet style clamp system for cable.


1. DFN free socket brief introduction:

SPRING F Series keyed, multipole connectors are ideal for instrument applications across many markets. SPRING CONNECTOR can widely used in kinds of harsh environment and applications, like Medical, Test & Measurement, ResearchCommunications, Broadcast Connector, Machines, Defense, RoboticAerospace, public sector, Information Systems, MotorsportMiscellaneous applications. Connector assures a reliable connection with corresponding Fischer core connector and connector of other companies of the same type making it.

2. DFN free socket description:

  • security of the Push-Pull self-latching system
  • multipole types 2 to 9 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.

      If you have purchased fischer 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 N).

      You can also use the selection guide
