How to Choose a Manufacturer for Custom 2-Pin or 4-Pin Magnetic Connectors?

Pin count follows the circuit, not the trend. Two pins carry power only; four pins add identification, temperature feedback or in-place detection. Before deciding, list every function the accessory must support and let the pin map follow that list.

Then check the mechanical side: available footprint, pitch, mating direction and how the user separates the connector. A 2-pin design saves space but leaves no room for accessory recognition, while a 4-pin design supports smarter charging logic at a slightly larger footprint.

Send us the function list, available space and target current, and we will propose the contact layout, pitch and retention force with a drawing you can review.
