Abstract: A sensor unit includes at least one sensor and at least two busbars. The busbars have first ends forming an internal electric interface for contacting the sensor and second ends forming an external electric interface for a connection cable or a plug receiving area. An injection-molded plastic housing defines the outer shape of the sensor unit and forms a sensor receiving area with a through-opening, which holds the sensor. The housing partly encases the busbars such that the internal electric interface is at least partly free and accessible near the sensor receiving area and the external electric interface is formed within the housing. The sensor and the internal electric interface are surrounded by a potting compound in a media-tight manner to form a sealed sensor head. The potting compound is formed of a material that can be processed at lower pressures and/or temperatures than the plastic material of the housing.

Abstract: A sewing installation for the production of a piped pocket opening in a cloth workpiece comprises two cutting units each with a corner cutting knife, which have two knives each. For the production of straight or diagonal corner cuts, one knife of a corner cutting knife is pivotally adjustable about an axis in the direction of the incision which substantially constitutes the pocket opening.
