New Versions Added to the "DF02 Series" of Industrial I/O Connectors

New Versions DF02 series of Industrial I/O Connectors supplied by JAE electronics

JAE has increased the variety of available options for the DF02 Series family of connectors. The DF02 series is an interface connector that is compatible with the half-pitch (1.27mm) standard used in the industrial equipment market.


JAE manufactures and sells this EMI-resistant, compact, and light weight connector series, which features a plastic hood with a nickel plating finish. The DF02 Series was developed to meet the growing need for environmental resistant, small, light, and cost-saving connectors for use in advanced industrial equipment.


Now a version with a non-nickel plated hood has been developed to add to the DF02 Series line-up. The hood was developed with customer usability in mind. The hood design prevents breaking from over-tightened screws, ensure a ground connection between devices with an integrated ground bar, and offers exceptional workability and quality.


  • Ground plate in the hood ensures ground connection.
  • Harness workability is improved by the hood temporary positioning structure.
  • Workability is improved by the assembly nut integrated in the hood.
  • A spacer on the mating screw prevents breakage and distortion of hood from excess tightening of screw.
