Description
The DOL 27 sensor is a 30 mm capacitive proximity sensor designed to detect loose and solid materials. The DOL 27 and iDOL 27 sensors are available in SCR, PNP and NPN output versions. The sensors are suitable for use with contactors, relays, PLCs, etc. in the agricultural and industrial sectors, in particular in enterprises for grain level measurement and effective feed level control in poultry houses, pig houses, and cowsheds. SCR output versions are available in 2-wire versions, as well as PNP and NPN in 4-wire versions. LED indicators display the state of the capacitive sensors, providing reliable monitoring of filling and emptying processes.Benefits and warranty

Capacitive Sensor DOL 27 CA-P-M30-NF-CA-SCR-M-2T with Make Logic
The capacitive sensor DOL 27 CA-P-M30-NF-CA-SCR-M-2T is a powerful 30 mm sensor designed for systems requiring active start control. The model features a threaded M30 housing and operates with Make (NO / Normally Open) logic. This means that upon detecting feed, the sensor closes the contact, sending a signal to start equipment or trigger an alarm.
The device supports universal voltage SCR 20–280 V (AC/DC) and comes with a full set of settings (2 trimmers). The increased housing diameter ensures better detection stability compared to smaller models, making it ideal for large hoppers and central augers.

Advantages of the DOL 27 Model with Make Logic
- Active Start (Make). This sensor is created not for stopping, but for action. It is ideal for "See feed — start mechanism" scenarios or for overflow alarms.
- M30 Reliability. The 30 mm diameter housing has a larger sensor area. This allows it to "see" through thicker walls and ignore dust buildup better than M18 models.
- Universal Power. Works on both 24V and 220V, easily integrating into any automation scheme.
- Precise Adjustment (2T). Sensitivity and Delay trimmers allow filtering out accidental triggers and tuning the sensor for a specific raw material type.
Applications of DOL 27 CA-P-M30-NF-CA-SCR-M-2T
This model is used for specific tasks:
- Back-pressure Sensors (Safety). Installed at critical points. If feed rises to the sensor (blockage), it closes the emergency siren circuit.
- Intermediate Hopper Control. When the container fills up, the sensor signals to start the next transport line.
- Large Outdoor Silos. The powerful M30 sensor works better in conditions of temperature changes and thick walls.
Technical Specifications
| Characteristic | Value |

Installation of DOL 27 M30 Make Sensor
- Installation: Prepare a 30.5 mm hole. Fix the sensor with nuts. M30 ensures very secure mounting.
- Connection: 2-wire, series. Remember: while there is no feed, current does not flow (open circuit).
- Adjustment: Adjust "Sens" and "Time" under the cap.
DOL 27 Make is a reliable choice for active control systems.
