\$\begingroup\$

after finishing my prototype PCB I am now tasked to fit it inside a machine with almost no space. The PCB is not the problem but the Wire-to-board connectors.

After intensive search I was very overwhelmed of the selection. I narrowed it down to the JST-PH (horizontal 4.6mm) and the Molex DuraClik (6.4mm).

Do any of you know a flatter design, or an alternative?

  • \$\begingroup\$ I did not think about flat ribbons. I will look into that \$\endgroup\$ – v3xX Sep 16 at 8:02
  • \$\begingroup\$ If you want to use wires, check the JST SH connector, with a height of 2.9 mm. The Molex PicoBlade system is closely following with 3.4 mm \$\endgroup\$ – Huisman Sep 16 at 8:13

(I definitely find this topic useful, but it will be(come) obsolete; my previous remark is from a research done 4 years ago and therefore outdated) \$\endgroup\$ – Huisman Sep 16 at 8:19
