Yes they come with quadrature encoders, standard 2500.

To stop the motor moving when the power is switched off, which is useful if for instance the motor is running a Z-axis which could drop with no holding torque. The brake is rated for slightly greater than torque than the motor, so it's not much use as a spindle lock unfortunately.
