Best CAN Connector Interface

[Al Skierkiewicz]

Toast,
There are a number of connectors that work in this application. All of them available from Digikey (First sponsor in Minnesota). If you have good soldering skills and can handle the cost, Switchcraft makes a mini version of their XLR connector line. These connectors latch together so they won't pull apart in high G collisions and are available in 4 pin version. My personal recommendation is to select a connector solution that can easily be pulled apart and then allow the offending device to be isolated by connecting to the remainder of the string.

Why would you want 4-pin connectors for this application? Do you use chassis harnesses, doubling the number of connections over a daisy chain? If not, you would have to attach half of the devices to each other by hard connections on one side of the connectors, which doesn't help much when it comes time to repair.

Gus,
If your robot design would have the connectors removed from the devices by some distance, four pins would allow the bus to go to and return from the device.
