Product details

2.50 mm straight plug, 2-conductor mono

The MP-2511 is a 2-conductor mono phone plug from CUI Devices, accepting a 2.50 mm industry-recognized mating diameter (0.094", 3/32", sub-miniature). Rated 1 A at 12 VDC with nickel-plated brass contacts and solder termination, the plug is unshielded and mounts free-hanging in-line.

2.50 mm vs 3.50 mm — MP-2511 and MP-3521

The MP-2511 uses the 2.50 mm sub-miniature diameter, while the MP-3521 uses the 3.50 mm mini-plug diameter — the two do not share a common jack and are not cross-compatible without changing the mating receptacle.
