DOL 27 Capacitive Sensor

A 30 mm capacitive proximity sensor designed for detecting loose and solid materials.

No more burned off sensors due to installation mistakes
The DOL 27 and iDOL 27 capacitive proximity sensors are immune to EMI, short circuits, and any overload which prevents sensors from burning off due to installation mistakes. The sensors come with IP69k and NEMA 1/3/4/6/12/13 environment protection.

Very low power consumption in off state
The sensors have very low power consumption in off state, enabling the possibility for sensors working in parallel on the same contactor. This gives the sensors a unique possibility for controlling cross auger systems.

Different versions for different needs
DOL 27 and iDOL 27 are available in SCR, PNP, and NPN output versions. The sensors are suitable together with contactors, relays, PLC’s, and similar within the agricultural and industrial sectors. SCR output versions are available in 2-wire versions PNP and NPN output versions are available in 4-wire versions.

Easily adjusted
The ON and/or OFF delay, MaxRunTimer, Make / Break contact, and sensitivity of the sensor can be ﬁxed or adjusted using a trimmer or the SmartAdjust App to suit different motor control units

Easily mounted
The sensor can be easily mounted from the outside of a silo by using the gland we made for mounting.
Beneﬁts

Accurate detection of loose and solid materials
Avoid drilling since the sensor can be mounted on the outside of plastic hoppers
Mounting from the outside of the silo

Advantages

Low power consumption
Easily adjusted
Easily mounted
IP 69k and NEMA 1/3/4/6/12/13 environment protection

DOL 27 and iDOL 27 capacitive sensors

DOL 27 / iDOL 27 is a capacitive sensor for detection of loose and solid materials.
SCR output versions are available in 2-wire versions. PNP and NPN output versions are available in 4-wire ver-sions.
The products are suitable together with contactors, relays, PLC’s and similar within the agricultural and indus-trial sectors. DOL 27 / iDOL 27 is immune to EMI, short circuits and any overload. The mechanical design makes DOL 27 / iDOL 27 ideal for integration into applications with limited space. 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.

RELIABILITY
The sensor’s electronics are completely embedded in a thermoplastic casing. This achieves a very high resistance to moisture and other external influences in aggressive environments. The sensor is CE, C-UL and UL approved and has a high immunity to noise from electric communication (e.g. from mobile phone) and transients (e.g. from motors and contactors). This makes the sensor very reliable and dependable in operation.
Adjustment

DOL 27 / iDOL 27 is available with different functions
DOL 27 has trimmers with different functions depending on its type
iDOL 27 settings can be adjusted with the SmartAdjust app.

Functional description
