On my pcb I need a 2-pin female wire-to-board connector on which 120V DC will arrive.
What is the standard way to approach this? (I got this one for example)
Thanks!

1\$\begingroup\$ Asking for product recommendations is generally off-topic as the products can change and the answer will not change. Then people in the future will find the question with out-dated recommendations \$\endgroup\$– Criticize SE actions means banCommented Nov 25, 2022 at 14:49

1\$\begingroup\$ It's not a part recommendation, but IMHO a question about a connector type. What current does it carry? \$\endgroup\$– tobaltCommented Nov 25, 2022 at 14:54

1\$\begingroup\$ You need to specify in great detail what you actually need for a question like this to be acceptable. Board to board, board to wire? If wire what AWG? Clearance/creepage/isolation requirements? Why female? Current requirements? Indoors/outdoors? Temperatures? Preferred soldering method, SMD or through-hole? And so on... \$\endgroup\$– LundinCommented Nov 25, 2022 at 15:02

Do not use a female connector for a power inlet: the male plug for it is unsafe.
Instead, use a female plug on the power cord and a male inlet on your board.
Any wire-to-board connector with a pitch of greater than 2.54 mm will work. A standard solution is a 3.96 mm pitch, single-wall, wire-to-board connector. (My site.)
The volatge rating can be increased by skipping the middle pin (as shown in this picture). The plug in this picture is latched, though unlatched plugs are more common.
You can buy the male PCB header here and the female plug housing here.

\$\begingroup\$ Thank you! On Digi Key I searched for 'wire to board' and filtered for both pitch>2.54mm and molex. But I can't find male/female (contact type) in the filters I attach a link to the research: digikey.com/short/jq81dvdd \$\endgroup\$– KaleMCommented Nov 25, 2022 at 15:54

\$\begingroup\$ Probably because I looked for Terminal Blocks Categories. In this category there are 'Headers, Plugs and Sockets' (the green ones) ... would that be OK for this application? \$\endgroup\$– KaleMCommented Nov 25, 2022 at 15:59
