Appreciate these images andyes, it would appear that the new speed sensor is not for your particular machine/model.

For a ProFrom 725, the speed sensor is P/N 102955 and may be confirmed / inquired from HERE.

The part we order was incorrect? We should order the one you have attached? Thank you for your time
Expert:  Louie replied 10 months ago.

From the picture provided, the part that was ordered appears to be a 2-wire cable with connectors at both ends or a connector and a small elongated / rectangular module.

From the pictures of the motor posted, the speed sensor appears to be using a 3-wire cable with 2-connectors. The speed sensor itself is a small board with 2 blocks where the slotted disc passes through when turning.
