DOL 26 amniotic grain level sensor CA-P-M18-NF-CA-PNP-2-1T, 105126

What is the DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive grain sensor and what is it used for?

The DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive sensor is a balanced model of the series, equipped with one adjustment trimmer (1T). It is created for situations where the operator only needs to adjust the sensor's sensitivity to the feed type (grain, meal, pellets), while the time delay parameters remain fixed by the manufacturer.

The sensor has a threaded M18 housing and a universal complementary PNP (NO + NC) output. This means it has 4 wires and allows choosing the operating logic (normally open or normally closed) directly during installation by connecting the corresponding cable wire.

Key advantages of the DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive sensor

• Simple setup (1T). The presence of only one trimmer (Sensitivity) simplifies the calibration process. The operator will not get confused between time and sensitivity settings — only the reaction to the material is adjusted.
• Double output (NO + NC). Maximum integration flexibility. You can use this sensor both to start mechanisms (NO) and to stop them (NC), or even for both tasks simultaneously.
• Threaded mounting (M18). Rigid fixation with nuts eliminates sensor displacement from vibration, guaranteeing a stable activation point.
• PLC Compatibility. Standard PNP output ("positive" control) is ideal for modern microclimate computers and feed distribution controllers.

Applications of the DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive sensor

This model is ideal for facilities with variable rationing:

• Lines with different types of feed. If you feed pellets today and wet mash tomorrow — the 1T trimmer allows quickly readjusting the sensor to see the feed but ignore dust.
• Systems with external timers. If the time delay is implemented in the controller (computer) itself, then a sensor with a timer (2T) is not needed — the 1T model will be a cheaper and simpler solution.
• Universal stock spare. Thanks to NO+NC outputs, this single sensor can replace any other faulty PNP M18 type sensor.

Why choose the DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive sensor

This is a choice in favor of reasonable sufficiency. You get the opportunity to adapt the sensor to "complex" feeds (thanks to sensitivity adjustment), but do not overpay for the timer function if you do not need it.

Mounting and setting up the DOL 26 CA-P-M18-NF-CA-PNP-2-1T capacitive sensor

1. Connection (4 wires):
   - Brown (+), Blue (-) — power.
   - Black — is the NO output (closes on feed).
   - White — is the NC output (opens on feed).
   Choose the required wire, insulate the other.
2. M18 Mounting: Install the sensor in the hole and tighten with nuts. The NF head must protrude inward.
3. Calibration (1T): There is only one screw on the housing. If the sensor "does not see" feed — turn clockwise. If it sees dust as feed — counter-clockwise.

Comparison of model 1T (Sens) with model 2T (Sens+Time)

What is the difference in use:

Choose the 1T model if delay control is handled by an external controller, and you only need a high-quality "eye" for the system.
