All characteristics
Description
The DOL 26 capacity sensor is a small sensor that is suitable for use in feeders. Due to its mechanical design, the DOL 26 is ideal for use in small systems with limited space, such as in feeders in poultry farms, pig farms or cow sheds. The sensor is therefore out of reach of the animals. It withstands difficult environmental conditions and measures the feed level in hoppers and feeders well.Benefits and warranty

What is the DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor and what is it used for?
The DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor is a high-voltage universal model of the DOL 26 series, equipped with a thyristor output (SCR). Its main feature is the ability to operate in a wide voltage range from 20 to 280 V AC/DC without additional adapters.
This model features Break (NC / Normally Closed) logic. This means it is ideally suitable for the "emergency stop" function or filling control: the sensor breaks the electrical circuit as soon as the feed level reaches its sensitive zone.

Key advantages of the DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor
- "2-Wire" Connection. This sensor is connected in series with the load (contactor coil), which significantly simplifies installation and saves cable when upgrading old systems.
- Voltage Universality. It does not matter what your control voltage is — 24V, 110V, or 230V. The sensor automatically adapts to the network.
- Interference Protection. The SCR thyristor output is highly resistant to electromagnetic surges, which often occur when starting powerful electric motors.
- Full Control (2T). Two trimmers allow you to precisely adjust not only the activation point but also the reaction time, filtering out false signals.
Applications of the DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor
This model is indispensable in systems where there is no low-voltage power supply:
- Direct control of 220V contactors. Used in control cabinets without 24V transformers.
- Replacement of mechanical "flags". Installed at the end of distribution lines instead of unreliable mechanical switches, increasing system stability.
- Top level control in silos. Thanks to the IP69K housing, it can work outdoors, stopping the auger loading when the bin is full.
Why choose the DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor
This is the choice of electricians and engineers who value simplicity. You do not need to run separate power lines — just connect the sensor in series with the relay coil control wire.
| Parameter | Value for this model |
|---|---|
| Output type | SCR (Thyristor) |
| Operating voltage | 20 – 280 V AC/DC |
| Logic | NC (Normally Closed / Break) |
| Number of wires | 2 wires |

Mounting the DOL 26 CA-P-M18-NF-CA-SCR-B-2T capacitive sensor
- Series connection. Attention! The SCR sensor is never connected in parallel to the power source. It must always be connected in series with the load.
- Leakage current. Keep in mind that even in the off state, a micro-current flows through the sensor to power the electronics (< 3 mA). For modern relays, this is not critical.
- Mechanical installation. Install the sensor in the plastic adapter so that the active part (NF) protrudes inside the container by at least 10 mm.
Comparison of DOL 26 CA-P-M18-NF-CA-SCR-B-2T with PNP analogs
What is the key difference between the SCR version and standard DC sensors:
| Characteristic | DOL 26 SCR (This model) | DOL 26 PNP |
|---|---|---|
| Voltage type | AC / DC | DC Only |
| Wiring complexity | Simple (2 wires) | Standard (3-4 wires) |
| Compatibility | Old and new 220V networks | Modern controllers only |
If you have a "classic" automation scheme on 220V or 110V contactors — this model is the unrivaled option.
