I'm trying to connect to the RS485 of my stove/furnace and it has a strange connector for this. I want to intercept the existing physical connection, so I need both plug and receptable.
Plug (each pin ~4x4 mm, total ~8x8 mm):
Receptacle (Outside dimensions: 9.5x9.5 mm):
It actually looks like a Molex Minifit connector, but it is not really. The size fits exactly, but the 2x2 Molex Minifit Connection has two rectangular holes and two trapezoid holes. This connection I have here only has one trapezoid hole.
I actually bought 2x2 Molex Minifit connectors and they don't fit. I also checked the Molex Microfit and they also don't seem to be the right thing.
How is this connector called and where can I buy a plug and a receptacle? Or, even better, where can I buy an extension cord (1:1 mapped) so I don't have to crimp my own cable?
