The light signal is delivered to a through hole (14), which is closed in a sealed manner by a partial-transparent cover (15). A medium passes through and to a through hole (20), which is closed by a partial-transparent cover (21) in a sealed manner. One of the covers is arranged in the recess of the assigned housings, where an adhesive layer fills a gap formed between the cover and the housings.
