An electronic device (1) has a can housing (3) and a method for producing the same. The can housing (3) has an open end face (4). A plug-in unit (5) can be inserted into the can housing (3) through the end face (4). The plug-in unit (5) has a populated circuit board (6) and a multicontact connector (7). The can housing (3) has an integrated connector collar (8), which integrally extends the can housing (3) and surrounds the multicontact connector (7) and contact elements (9). The connector collar (8) forms a fit for a mating connector. The insert has the circuit board (6) and a contact carrier (10) having the multicontact connector (7) without the connector collar (8). The outer contour (11) of the contact carrier (10) is at least partially matched to the inner contour (12) of the connector collar (8).
