Go to Post So kudos for asking advice... you've got plenty of good advice so far in this column... but honestly, if Orville and Wilbur Wright had taken good advice they would have packed up and gone back to their bicycle shop. - dtengineering [more]

Re: Best CAN Connector Interface

The Molex connectors Jim listed look fantastic. I stayed closer to the 0.1"-spaced Molex connectors used for PWM. Amphenol makes a locking variant of those: A34186-ND and A34216-ND

Those connectors are designed for IDC (insulation displacement)... you're supposed to press the unstripped wire onto the connector, and sharp edges will penetrate the insulation and make contact. I found this unreliable, particularly with the yellow wire used on the Talons. It also make it very hard to slide the contact inside the housing. I had MUCH better luck soldering them instead.

Pick up some 120-ohm resistors and you can make terminators, too. Then your layout won't require you to make the PDP the last device in your chain.

Strange thing about those connectors and DigiKey, they're like hot dogs. You can only order one type in multiples of 8, the other in multiples of 10.

This is a more compact version of the lever nut from Wago that works really nice. am-2575a

We used those exclusively for our CAN network this year and they've worked well. Their ease of use beats other methods in my book; no crimps to over torque, no solder joints to booger. We have the larger predecessor model that was previously mentioned, and they did prove to be a bit bulky for this application.
