DOL 26 Small Capacitive Proximity Sensor
The DOL 26 Capacitive Proximity Sensor is a small 18 mm sensor, ideal for confined spaces such as inside poultry feeders. This keeps the sensor out of the animals' reach. It is available in an iDOL version with NFC for configuration via SmartAdjust app.
Benefits
- Rugged design for agriculture
- Different versions for different needs
- Low power consumption
- Easy to adjust

DOL 26 sensors are small sensors designed for feeders
The mechanical design of DOL 26 makes it ideal for small applications with limited space, such as inside feeders on poultry farms. This keeps the sensor out of the animals' reach.
Detects bulk and solid materials
DOL 26 is a capacitive proximity sensor for detecting bulk and solid materials such as feed, plastic or wood pellets, grain and bedding. For example, it can help ensure sufficient feed distribution in livestock houses or deliver the right quantity of pellets to a pellet stove.
Rugged design for agriculture
DOL 26 is specifically designed for harsh livestock-house conditions, withstanding high humidity and heavy dust. The proximity sensor has full temperature compensation over a wide temperature range. DOL 26 is resistant to electromagnetic interference, short circuits and any overload. No more sensors burned out by installation errors!
Different versions for different needs
Reading the configured time delay
Low power consumption
The DOL 26 sensor consumes very little power when off. This allows sensors to operate in parallel on the same contactor.
Easy to adjust
DOL 26 is easily adjusted using only a screwdriver. Sensor sensitivity can be fixed or adjusted with a trimmer to suit different feed types. Its on/off delay and MaxRunTimer can be fixed or adjusted with a trimmer to suit different motor control units.
The iDOL 26 sensor can be configured using SmartAdjust app.

DOL 26 smooth housing with return cable

DOL 26 threaded housing with return cable
Smooth or threaded housing with angled cable outlet
DOL 26 has a unique design with an angled cable outlet. This return-cable option makes it easier to install the sensor inside feeders, where sensors often need to be turned upside down. The return cable avoids the need to bend the cable back, reducing the risk of cable damage.
When installed inside the feeder, the sensor is out of the animals' reach and therefore better protected.

Smooth and threaded housings with straight cable
DOL 26 comes in smooth or threaded housings as SCR, PNP and NPN sensors with different voltages (10-36 V DC or 20-280 V AC/DC).
The sensor comes with an M12 cable in PNP versions (smooth and threaded) and NPN versions (threaded).
These variants can be made with two trimmers or no trimmers.

iDOL versions with NFC
DOL 26 is available in an iDOL version with NFC. NFC versions can be configured using SmartAdjust app. The app lets you do more with one sensor. For example, you can set iDOL sensors for an on/off delay and Max Run Timer simultaneously. Settings can be copied to multiple sensors, allowing identical configurations to be prepared before installation.
iDOL 26 sensors come with a straight cable and smooth or threaded housing, or with a return cable and threaded housing.

Choosing DOL 26
DOL 26 is a compact capacitive sensor for detecting loose and solid materials where installation space is limited.
First define the required output and supply: the technical guide distinguishes SCR (2-wire connection, 20–280 V AC/DC) from PNP/NPN (4-wire connection, 10–36 V DC). Then select the exact item from its full name and SKU in the variants below. Confirm the selected model against the project wiring before installation.
