Can anyone recommend a single position receptacle for wire to board that is good for repeated insertion/removal?

I don't fine the generic "dupont" connectors (pictured below) to be very durable for single position use, after a few insertion/removal cycles the contact starts to loose tension.

The "official" Amphenol Mini-PV single position (65039-036LF) is oddly expensive at $1.50 each.

I could have sworn I've used a TE/Molex part that came in single position receptacle and had a better quality contact but checking KK254, CGrid III etc everthing starts at 2 position. 

Thanks!

I knew I'd seen an AMP.   I much prefer the inner connector on this.    Can anyone ID it?

It’s one of the AMPMODU series, either MOD II or MOD IV, IIRC.

FYI, what also works is to use genuine Mini-PV contacts in cheap Chinese DuPont housings.

Sorry. Forgot to follow up. Finally got a reply from AMP that it was  87175-2 ampmodu as you say. I ordered some samples to confirm.

To me the AMP contact looks even more durable than the genuine mini-pv as the housing is rectangular allowing more space.

Regardless. I didn't know the genuine mini pv fit the clone housings, I'll buy some.  Thanks for suggesting.

I've been buying Harwin M20 terminals for this sort of purpose and they've been pretty solid.  They're the same basic design as the generic 'dupont' connectors, but, ya know.... good.  Offhand I don't know if they make a single-position housing.  I often don't bother with the plastic shell for single connectors (like squid cables) and just cover them with heat shrink instead, which makes it easier to fit multiple single connections next to each other on a header, and a little easier to write labels on.  They'll fit into the generic 'dupont' housings though, and I have a bunch of those hanging around from pulling them off of cheapo jumper wires.

The M22 series is the 2mm pitch equivalent. I tend to use 1.5mm pads on a 2mm pitch for test points, so on development units I'll solder on a 2mm header to connect the M22s to.  Like the M20s, they have a self contained spring contact so you can use them with heat shrink instead of the plastic housing for individual connections.
