DFMC 0,5/ 4-ST-2,54 - PCB connector

PCB connector, nominal cross section: 0.5 mm2, color: black, nominal current: 6 A, rated voltage (III/2): 160 V, contact surface: Gold, contact connection type: Socket, number of potentials: 8, number of rows: 2, number of positions: 4, number of connections: 8, product range: DFMC 0,5/..-ST, pitch: 2.54 mm, connection method: Push-in spring connection, conductor/PCB connection direction: 0 °, plug-in system: COMBICON DFMC 0,5, locking: without, mounting: without, type of packaging: packed in cardboard

  • Gold-plated contacts ensure transfer quality remains stable over the long term
  • Time saving push-in connection, tools not required
  • Defined contact force ensures that contact remains stable over the long term
  • Intuitive operation due to color-coded actuating push button
  • Optimized for tight installation situations: operation and conductor connection from one direction
