Looking for long range SPE alternative to 300-ft max twisted pair with similar bandwidth

These dimensions include the chassis for the product

SPE ports are pretty bulky, an option to have just solder pads instead would help with integration into small/tight spaces on a robot.

Have a connector that you can add an RJ45 + magnetics to as an option so that the main board can be smaller if you don't need an RJ45 port.

Add an RJ-45 port for standard 1000BASE-T ethernet for the uplink port

Add an SFP to the switch. This would add considerable size, and some cost.

We would use the Phoenix Contact SPE port (MPN: 1163797) because it is the smallest available. Standard wires can be adapted to this connector using MPN: 1343953
