Abstract: A sensor for measuring a parameter at a measurement point of a surface by means of direct contact. The sensor includes a sensor element arranged movably in the sensor and a spring element that can resiliently absorb an application force with which sensor element is pressed against the measurement point.

Abstract: A coupling system includes an optical plug-in connector, a coupling partner and a retaining element. The housing of the plug-in connector is provided with a sliding key and with two springy detent limbs which include a detent nose for engaging with the coupling partner. In order to receive the plug-in connector, the coupling partner is provided with a plug inlet which has recesses that correspond to the detent noses of the plug-in connector. A retaining element includes a laterally displaceable outer housing and an inner housing that is pivotally arranged therein. A locking element is provided as a two-limb lever that is arranged on the inner housing and that serves to lock the plug-in connector in the retaining element. When inserting the plug inlet, this locking is released once the plug-in connector and plug inlet are engaged with one another.

Abstract: The invention relates to a management-capable splice cassette for the telecommunication and data technique, for receiving carrier shells for two glass fibers each. A housing is provided with a cable connection device and a carrier is connected to said housing. The carrier shells are connected to the carrier in a rotatable manner. The management-capable splice cassette is exchangeable with other splice cassettes and can in particular be inserted in prior art splice cassette housings instead of the conventional splice cassettes. The invention provides an available reserve length and a small constructional height as well as an economical and simple handling. The carrier shells are disposed in at least two adjacent receiving portions and stacked upon each other, each of carrier shells is rotatably supported into a latch position at one of their sides.
