DOL 26 capacitive sensor CA-P-M18-NF-CA-PNP-2-2T, 105102

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

The DOL 26 CA-P-M18-NF-CA-PNP-2-2T capacitive sensor is a specialized sensor version with extended functionality for precise agricultural control. Unlike basic models, this modification is equipped with a built-in timer (2T function) and features a PNP transistor output. It is designed to control the level of bulk materials (feed, grain) in conditions where maximum signal stability is required.

The main feature of this model is the ability not just to "see" the feed, but also to control the on/off delay. This prevents frequent motor starts when the feed level fluctuates, significantly extending the equipment's lifespan.

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

• Time delay function (2T). The sensor has two trimmers: one adjusts sensitivity, and the second adjusts the delay time. This allows setting it to ignore short-term drops in feed levels.
• PNP Output. Compatible with most modern automation controllers and relay circuits (positive logic).
• NF (Non-Flush) Design. The sensitive head of the sensor protrudes from the housing. This ensures a wider detection field and better reaction to light bulk materials compared to "flush" sensors.
• M18 IP69K Housing. The compact 18 mm size allows mounting in hard-to-reach places, while being fully protected against moisture and dust.

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

This specific model is ideally suitable for:

• Final feed dispensing units (where auger shutdown delay is needed);
• Precise dosing systems (thanks to the fast reaction of the PNP output);
• Small hoppers and funnels (where standard 30mm sensors are too large);
• Automated lines controlled by PLC.

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

You choose this model when you need not just a presence sensor, but an intelligent device that filters false signals thanks to the timer.

Mounting the DOL 26 CA-P-M18-NF-CA-PNP-2-2T capacitive sensor

1. Mechanical mounting: Since this is an NF (Non-Flush) type, the active part of the sensor must protrude into the hopper and not touch metal walls on the side. Use a plastic adapter.
2. Electrical connection: Connect the 4-core cable according to the PNP diagram. Ensure the load meets the specifications (max 500 mA).
3. Setup: Using a screwdriver, adjust the two trimmers: "SENS" (to ignore dust) and "TIME" (to set the required activation delay).
