Summary of change:
'''GenBoard currently uses two EconoSealIII connectors''' '''ECM connector aspects''' For next generation, we're looking for other types (although EC18 and EC36 would work): * '''We should remain on the lookout for other automotive specification connectors''' * optimizing '''size''' ** '''Box-height''' is a bit prohibitive with EconoSealIII ** I noticed that '''100mm board maxsize would seriously limit our choice'''. 114mm is much better. ** 10A is ideal for the few high-power pins, but for most pins, '''smaller centerline''' would be welcome (the combo-design SAAB is perfect in this way). * reliability (several good choices, sealed is a good idea) * availability (usual: 2 months, MOQ: 60 .. 150) * price - note that a very good ARM processor can be obtained for the price of a connector solution. The connector-saga suggests that it's better to have a very few powerful units (pincount=35 or 70) rather than many lower-pincount units (unless one likes DSUB :-) VemsFrontier/Boards should be in the ballpark, if boards's bigger size is increased to 114mm so that the tyco 2-825213-5 junior-timer header fits.

The footprint is not so much better than EC36 (for EC36 one line is closer to the edge). We cannot justify spending thousands of EUROs (and all the logistics nightmare) for questionable benefits.

A bit pricey (almost as pricey as the SAAB70, which is not exactly cheap itself) and one part is 12 weeks (another is MOQ=1000), but otherwise OK (higher initial order value than the EC18 + EC36 were together). '''Should I order the part now, that ships in 12 weeks?''' '''Can someone look up the related tyco receptacle and round rubber seal part numbers so we can get quote ASAP ? The MPT receptacles too, not the tape but the standalone ones that have superior crimpability.''' '''SAAB70: 60 microtimer + 10 junior power timer pins''' This is about 103 mm and is a wonderful connector for ECM-to-wire applications. Some of the microtimer pins would be bundled in pairs, because the 10 junior pins is a bit too few. 6 of them is on the left side, 4 is on the right.

These circular connectors aren't available in a right-angle PCB mount footprint - only vertical mount. Some other industrial connectors have this same design. It raises the question of weather we need a right-angle connector at all... We can probably get a thinner case profile, better sealing, and more robust connectors by mounting vertically. High voltage/current outputs can have their own low density plug if needed, while regular or sensor IO can be on a higher density plug. The downside is different mounting requirements, and possibly difficult routing on high-density connectors. I think these circular connectors are perfect as band-aid when more outputs are needed with better than DSUB.. sealing. For main connector we only have EC36, SAAB42 and SAAB70. It is already a nightmare to stock and pay for the connectors, let's not add more connectors unless absolutely necessary (like EGT, maybe knock). Since the SAAB70 is just a tiny bit more expensive than the SAAB42 (and more available), I'd even consider a wider design with easier layout.
