Front part Mini Flex UP1 – for blind wiring and motion detector

Space is often tight for installations in concrete and masonry. The Mini Flex UP1 front section from Spotbox creates additional installation space – ideal for blinds, motion detectors and sockets. Standard UP1 inlet boxes often offer too little installation space for this. With the Mini Flex UP1 front part, Spotbox offers a sophisticated solution for such applications. In combination with the Mini Flex installation housings, the result is a flexible and clean flush-mounted installation with significantly more space for cables, plugs and components.
More installation space than a classic UP1 inlet box
The Mini Flex UP1 front panel has been specially developed for installations where additional depth or more space for cabling is required. A larger installation space is particularly important for blind cabling with Hirschmann plugs or for motion detectors. The combination with various Mini Flex installation housings creates a flexible solution that can be optimally adapted to different installation situations.
Compatible with Feller SNAPFIX®
A major advantage of the system is its compatibility with the Feller SNAPFIX® mounting frame. This allows switches, sockets or motion detectors to be integrated easily and cleanly. The result is a professional and standard-compliant installation that can be used in both concrete and masonry construction.
Ideal for blind cabling
Hirschmann plug-in connections are often used in modern blind installations. These require more space than conventional cable connections. The Mini Flex UP1 front section offers sufficient installation space for this and enables clean cable routing with later access to the connections.
Flexible extensions for different installation depths
The system can be combined with various Mini Flex installation housings:
- EB housing Mini Flex ET 100
- EB housing Mini Flex ET 150
- EB housing Mini Flex ET 150 with transformer tank
This allows the installation depth to be optimally adapted to the respective installation.
