SENSOR DIMENSIONS
PRODUCT
DOL 26 is a capacitive sensor for detecting loose and solid
materials.
SCR output versions are available in 2-wire versions.
PNP and NPN output versions are available in 4-wire
versions.
The products are suitable together with contactors, relays,
PLC’s and similar within the agricultural and industrial
sectors.
DOL 26 is immune to EMI, short circuits and any overload.
No more burned off sensors due to installation mistakes.
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.
IP69k and NEMA 1/3/4/6/12/13 environment protection.
Fully temperature compensated in complete wide
temperature range.
