Recognizing a connector
« on: January 20, 2020, 02:29:00 pm »
Hello, what are the connectors on this board (or better what are they ripping-off)?

Are they VH? I do not have the board yet, so I cannot measure the pitch, but from the other components it seems around 4mm

Don't know what LED is there (3 mm?) near output conector but through-hole optocoupler (817) have about 4.6 mm wide case, so low voltage connector can be about 4 mm (3.96 mm) or 5 mm (5.08 mm). And high voltage connector I think has the same pitch (but 3 pin).
A3960H (=VH) type (or NX5080)?

I made some investigation. It seems to me that it is 4 mm pitch.

Don't know the name, but I am using for them female connectors from ATX computer power supplies, cut to the required size.  They have the same step and the same pin thickness.

ATX connector has 4 mm (4.14 or 4.20 mm) step.

Found the specs from mine (mean well PT-45), the mechanical drawings show the connector models.

They indeed look like the molex 5277, thank you!
