Unique design features

Twin shaft design:

Soldo units are a step above the competition with a unique split shaft design.

The lower part of the shaft is fitted and sealed on the body, the upper side is fitted and sealed on the cover.

- electrical components are protected against water dropping into the enclosure, even during opening the lid.

- you will never loose the matching with the indicator

- no possibilities to close the lid with a wrong indication position

This allows also installation where space is a factor, reducing needed clereance, to 4 mm.


Cams adjustment precision:

Soldo limit switches also have easy-set 3 degree cams for independent tool free adjustment.

Hassle free installation:

Pre-wired PCB switch modules ensure installation is worry free and allows easy installation and wiring directly into terminal strips. The pre-wired boards are conformal coated for environmental protection.
