DOL 27 is a 30 mm capacitive proximity sensor designed for detecting loose and solid materials. LED lights indicate the status of the sensors.
DOL 27 comes in an iDOL version with NFC for sensor adjustment via the SmartAdjust App.
DOL 27 is a 30 mm capacitive proximity sensor designed for detecting loose and solid materials. The sensor has highly unique functionalities for the agricultural and industrial industry. LED lights indicate the status of the sensors.
The DOL 27 sensor is immune to EMI, short circuits, and any overload which prevents sensors from burning off due to installation mistakes.
The sensor has IP69k and NEMA 1/3/4/6/12/13 environment protection.
The sensor has 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.
At dol-sensors we strive to make the best solution for our customers, who have very different needs. Thus, our sensors are all available in different versions and can be tailored to every specific need.
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.
DOL 27 has easy trimmer adjustment on a single turn 240 degree trimmer with linear or non-linear scale.
The iDOL 27 has easy adjustment by using the SmartAdjust App.For all iDOL products, download the programming SmartAdjust App from Google App Store. Simply by searching for SmartAdjust or scanning the QR code on the product.
Like all our 30 mm sensors, DOL 27 and iDOL 27 can be easily mounted from the outside of a silo by using the gland we made for mounting. All you must do is mount the gland on the outside surface of the silo and mount the sensor to it. For silos made of metal or thick material, you will have to drill a small hole in it for the sensor to work.
iDOL 27 with smooth housing can also be mounted with dol-sensors' T-piece for mounting on a 40-60mm tube with conveying system using only the T-piece and three zip ties.
The SCR SE series is specifically designed for applications where multiple sensors are connected in series, enabling smarter control, improved safety, and reduced system complexity.
Installation is simple and robust:
Each sensor is equipped with:
Connecting two or more capacitive sensors in series enables advanced functionality:
This approach is ideal for applications where precision and control are critical.
In feeding systems, inefficiencies can occur when equipment runs without material present.
By installing:
…the system ensures that the feed auger only runs when both conditions are met.
This prevents:
The DOL 27 with threaded housing is available as SCR sensor with 20-280V AC/DC voltage and PNP or NPN sensor with 10-36 V DC voltage.
DOL 27 also comes in an iDOL version with NFC with either smooth or threaded housing. The NFC versions can be adjusted with the SmartAdjust App. The app makes it possible to do more with one sensor. For example, you can configure your iDOL sensors to have on/off delay and Max Run Timer at the same time. It is possible to copy settings to multiple sensors allowing you to preconfigure sensors with same settings before installation.
