I've been tinkering away a little bit with the calipers as I believe someone asked for dimensions of the 6-pin probe connector. I've attached a drawing which should give all the details one might need. Also included is an updated .STEP (AP214) model to allow input into popular CAD programs. Again, if someone knows where to source these, I'm all ears. |

For those interested, here is how I solved the problem of round pins on 6-pin 2mm connector. There is a Mill-Max part number 3330-2-00-15-00-00-03-0 (Mouser part 575-3330200150000030) - and also Mill-Max 3330-1-00-15-00-00-03-0. These are bulk round pins, gold plated. I made a spacer from 3mm thick FR4, and plugged these pins into a right-angle PCB dual-row 2mm header. I cut a piece of 3 positions from the 40 pin header. Since the pins are thicker than regular 0.5mm pins of such header, one need to push them in rather strong. Once the pins are in the connector, I applied epoxy and pushed in additional FR4 spacer. This creates a nice angle connector which reliably plugs into the probe socket. When combined with the 3D-printed shell, this allows to build the probe PCB that fits. The picture shows two connectors: angle one to put on PCB, and a straight one which I used for connecting to logic analyzer. On the side note: I printed the shell from PETG filament. Because the walls are thin, they may split. Applying acrylic solvent cement (dichloromethane or dichlorethane?) "welds" and bonds the shell layers and makes it strong enough to latch on the probe connector. |

Does anyone know where I can get the mating (receptacle) 3x2 pin 2mm pitch connectors to build the extender for the probus? The standard 2mm connectors have too small holes and the probe pins do not go there freely. I found that a cutout from DVI connector (it has 1.94mm pitch) can be mated, but I am looking for a better solution... Or, alternatively, are there any receptacle pins that mate with Mill-Max round 0.8mm round pins? |

They have a lot of different receptacles. From their website: https://www.mill-max.com/products/match/mating-receptacles/3330 |

Are you sure type 04 is a serial number? It looks like at least sometimes it's an ascii version number, for the newer probes. Maybe for older probes it's a binary version number? ZD1000: 04 06 41 30 30 31 'A001' ZS1000: 04 06 31 34 38 32 '1482' ZS2500: 04 06 41 30 30 35 'A005' AP020: 04 06 96 18 00 99 Maybe 99 is 1999 and they changed the encoding at Y2K? :P |
