Title: What type of connector is this? (Happ Optical Board)
Post by: telengard on November 29, 2017, 10:51:36 pm

I am kitbashing an Omega Race spinner to use an optical encoder and am pretty much done, I just need to wire up the encoder.  But I have no idea what type of connector is is (pin spacing, etc).  Anyone know what I should look for?  See attached pic (my board is green but looks almost identical).

From their website:

What are the pin-outs of the Optic Sensor pcb A052-1010-00 and A052-1011-00?

These all use the same Item # A052-1011-00 Optic Sensor Board. The connections are as follows.
Pin 1 - Output A
Pin 2 - +5V
Pin 3 - GND
Pin 4 - Output B

Connector kind of looks like http://www.mikesarcade.com/cgi-bin/store.pl?sku=KK4PIP (http://www.mikesarcade.com/cgi-bin/store.pl?sku=KK4PIP)

It does look like a Molex KK series, but it is probably a KK 254 (http://www.molex.com/molex/products/listview.jsp?query=&offset=0&filter=&fs=&npp=20&sType=a&autoNav=&path=+inmeta%3Apromotable%253Dyes+inmeta%3ACollectionName%253DImpulse+inmeta%3Acategory%253DPCB%252520Headers+inmeta%3Abreakaway%253DNo+inmeta%3Acircuitsloaded%253D4%2526partialfields%3D%28productname%3AKK*%252520254%29&channel=products&rangeFlag=true&rangeInput=4&displayName=circuitsloaded) (0.1") series connector, not a KK 396 (0.156") series connector.

Break out the calipers and measure from the tip of pin 1 to the tip of pin 4.

- 0.3" = 0.1" pitch = Molex KK 254 (or possibly a Dupont connector like the ones used on motherboards, cooling fans, breadboard jumpers, etc.)

- 0.468" = 0.156" pitch = Molex KK 396

Twisty Wrist has a KK 254 4-pin housing here (https://www.twistywristarcade.com/100-kk-series/320-connector-housing-4pos-100-w-ramp-.html) (Molex P/N 22-01-2047) and female pins here (https://www.twistywristarcade.com/100-kk-series/322-terminal-female-22-30awg-tin.html) that will work with Molex headers # 6373 (http://www.molex.com/molex/products/listview.jsp?query=&path=inmeta:promotable%3Dyes+inmeta:CollectionName%3DImpulse+inmeta:ProductSeries%3D6373+inmeta:circuitsmaximum%3D4+inmeta:category%3DPCB%2520Headers&offset=0&autoNav=0&sType=a&filter=&fs=&channel=products&encode=true), 6410 (http://www.molex.com/molex/products/listview.jsp?query=&path=inmeta:promotable%3Dyes+inmeta:CollectionName%3DImpulse+inmeta:ProductSeries%3D6410+inmeta:circuitsmaximum%3D4+inmeta:category%3DPCB%2520Headers&offset=0&autoNav=0&sType=a&filter=&fs=&channel=products&encode=true), or 171856 (http://www.molex.com/molex/products/listview.jsp?query=&path=inmeta:promotable%3Dyes+inmeta:CollectionName%3DImpulse+inmeta:ProductSeries%3D171856+inmeta:circuitsmaximum%3D4+inmeta:category%3DPCB%2520Headers&offset=0&autoNav=0&sType=a&filter=&fs=&channel=products&encode=true).
