DOL 26SCR Serial
1 Product description
DOL 26 is a capacitive sensor for detection of loose and solid materials.
SCR output versions are available in 2-wire versions.
DOL 26SCR Serial is suitable for serial connection of sensors on the same load.
The products are suitable together with contactors, relays, PLC’s and similar within the agricultural and indus-
trial sectors. DOL 26 is immune to EMI, short circuits and any overload. The mechanical design makes DOL 26
ideal for integration into applications with limited space. The full-return option is especially suited for feeding
pans. Very low power consumption in off state – enables possibility for sensors working in parallel on the same
contactor. Unique possibility for controlling cross auger systems.

DOL 26SCR
DOL 26SCR:
Connect the sensor in series with the load. The polarity is unimportant.
The sensor is protected against overload and short circuit. If the output cur-
rent exceeds the nominal output current, the output function is switched off.
Remove the short circuit or choose a smaller load to remove the error. The
current limitation error is indicated on the sensor by double flashes followed
by a pause.
