Module for a laboratory sample distribution system, laboratory sample distribution system and laboratory automation system

A module for a laboratory sample distribution system, the module comprising:

• a transport plane to support sample container carriers, each sample container carrier comprising at least one magnetically active device;
• a plurality of electro-magnetic actuators stationary arranged below the transport plane, the electro-magnetic actuators move the sample container carriers on top of the transport plane by applying a magnetic force to the sample container carriers, wherein each electro-magnetic actuator comprises a ferromagnetic core, wherein adjacent ferromagnetic cores are magnetically coupled to each other by respective magnetic coupling elements;
• and
• a magnetic coupling enhancer for increasing magnetic coupling to adjacent modules, the magnetic coupling enhancer comprises,
• a plurality of magnetic coupling protrusions, each magnetic coupling protrusion positioned between an outer edge of the module and a corresponding ferromagnetic core of an electro-magnetic actuator positioned adjacent to the outer edge, and/or
• a plurality of contact surfaces, the contact surfaces are be contacted by a corresponding number of magnetic coupling rods.
