An electromechanical latch is described herein. The electromechanical latch is a dual-actuator latch, wherein a first actuator and a second actuator are driven with precise timing to move a first latch part relative to a second latch part, and vice versa. When the electromechanical latch is in a closed position, the first rotary latch part is positioned to prevent rotation of the second rotary latch part in a first direction. To transition the electromechanical latch from the closed position to an open position, the first actuator drives the first rotary latch part such that the second rotary latch part is able to rotate in the first direction. Thereafter, the second actuator drives the second rotary latch part in the first direction until the electromechanical latch is in the open position.
