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-F-CA-SCR-B-2T
The capacitive sensor DOL 27 CA-P-M30-F-CA-SCR-B-2T is a specialized modification of the 30mm sensor for Flush mounting. Unlike standard models, the active head of this sensor does not protrude beyond the threaded housing. This design significantly reduces the risk of mechanical damage to the sensor by heavy feed flow or moving parts.
The model operates on universal SCR 20–280 V (AC/DC) voltage with Break (NC) logic — stopping the line when full. The presence of two trimmers (2T) allows for precise calibration, and the "Flush" housing type focuses the sensing zone strictly forward.

Key Differences of the Flush (F) Design
- Mechanical Protection. Since the sensor has no protruding parts, it cannot be accidentally knocked off by grain flow. Ideal for narrow spaces.
- Directed Sensitivity. The design shields the sensor from the sides, so it reacts less to feed buildup on the mounting pipe walls.
- SCR Versatility. Support for a wide voltage range (AC/DC) allows using the sensor in any system.
- Flexible Adjustment (2T). Sensitivity and Delay trimmers allow adapting the sensor to specific conditions.
Comparison of Mounting Types: Flush vs Non-Flush
Why choosing the right body type matters:
| Characteristic | Flush (F) - This Model | Non-Flush (NF) - Standard |
|---|---|---|
| Appearance | Flat face, flush with nut | "Mushroom" head protrudes |
| Sensing Zone | Forward only (directed) | Forward and sides (volumetric) |
| Effect of Buildup | Minimal (ignores walls) | Medium (may trigger) |
| Damage Risk | Low (hidden) | Higher (exposed) |
Applications of DOL 27 CA-P-M30-F-CA-SCR-B-2T
This model is recommended for:
- Narrow Pipes. Where a protruding sensor would block flow.
- Heavy Feeds. Where flow has high kinetic energy.
- Flush Mounting. To create a smooth inner hopper surface.
Technical Specifications
| Characteristic | Value |
|---|---|
| Mounting Type | Flush (Embedded) |
| Housing | M30 (30 mm) |
| Logic | Break (NC / Stop) |
| Power Supply | 20–280 V AC/DC |

Installation of DOL 27 M30 Flush Sensor
- Installation: Screw in so the face is flush with the inner wall.
- Connection: 2-wire scheme, in series.
- Adjustment: Due to Flush design, detection range is slightly shorter (10-12 mm), adjust "Sens" carefully.
DOL 27 Flush offers maximum protection and reliability.
