Conveyor device, comprising: - several conveyor zones, each having a conveyor drive for generating a conveying force on an object disposed in the conveyor zone, - a plurality of control units (10, 100), every control unit being assigned to at least one conveyor zone, a data bus cable (2, 102, 202, 302) which connects the control units to one another, and - every control unit has a connector device (31, 141) for a data bus cable and the connector device comprises a cross-sectional recess (33, 33a,b) in the region of which a first and a second electrical contact pin (34a,b) are disposed, which are configured to establish an electrical contact between a first and second conductor of a data bus cable inserted accordingly in the cross-sectional recess and the control unit due to the fact that the contact pins in the region of the cross-sectional recess are able to penetrate an insulating sheath of the data bus cable to the extent that the first electrical contact pin makes electrical contact with the first conductor and the second electrical contact pin makes electrical contact with the second conductor of the data bus cable, characterised in that - the several conveyor zones each comprise a sensor for detecting an object in the conveyor zone, every control unit being coupled with the sensor of the conveyor zone by signal communication in order to receive signals signalling the presence of an object in the conveyor zone and being coupled with the conveyor drive by signal communication in order to activate the conveyor drive, and - the data bus cable has a cable cross-sectional geometry which can be inserted in a cross-sectional recess (33, 33a,b) on the control unit in such a way that the cable cross-sectional geometry and the cross-sectional recess define an orientation of the data bus cable in the cross-sectional recess and thereby establish a contact protected against polarity reversal between the first contact pin and the first conductor and between the second contact pin and the second conductor. - several conveyor zones, each having a conveyor drive for generating a conveying force on an object disposed in the conveyor zone, - a plurality of control units (10, 100), every control unit being assigned to at least one conveyor zone, a data bus cable (2, 102, 202, 302) which connects the control units to one another, and - every control unit has a connector device (31, 141) for a data bus cable and the connector device comprises a cross-sectional recess (33, 33a,b) in the region of which a first and a second electrical contact pin (34a,b) are disposed, which are configured to establish an electrical contact between a first and second conductor of a data bus cable inserted accordingly in the cross-sectional recess and the control unit due to the fact that the contact pins in the region of the cross-sectional recess are able to penetrate an insulating sheath of the data bus cable to the extent that the first electrical contact pin makes electrical contact with the first conductor and the second electrical contact pin makes electrical contact with the second conductor of the data bus cable, characterised in that - the several conveyor zones each comprise a sensor for detecting an object in the conveyor zone, every control unit being coupled with the sensor of the conveyor zone by signal communication in order to receive signals signalling the presence of an object in the conveyor zone and being coupled with the conveyor drive by signal communication in order to activate the conveyor drive, and - the data bus cable has a cable cross-sectional geometry which can be inserted in a cross-sectional recess (33, 33a,b) on the control unit in such a way that the cable cross-sectional geometry and the cross-sectional recess define an orientation of the data bus cable in the cross-sectional recess and thereby establish a contact protected against polarity reversal between the first contact pin and the first conductor and between the second contact pin and the second conductor.
