Typical Application Cases of Pepperl+Fuchs NCN100-F23-E2-V1

Core selection premise: 100mm ultra-long sensing distance, non-flush, เลขที่ พี.เอ็น.พี, switching frequency only 10Hz. Suitable for low-speed position limit / presence detection, not for high-speed counting. ได้รับการจัดอันดับ IP67, -25~70℃, suitable for dusty, humid heavy-duty environments.

กรณี 1: End Limit for Bridge Crane / Overhead Crane Trolley (ที่พบบ่อยที่สุด)

อุตสาหกรรม: โลหะวิทยา, steel warehouse, heavy-duty workshop cranes

สารละลาย:

The sensor is mounted on the side of the crane rail. A stainless steel target plate is fitted at the end of the trolley. When the trolley approaches the rail end within the 81mm reliable operating distance, the sensor sends a PNP signal to PLC to trigger deceleration and emergency stop protection, preventing rail overtravel.

ข้อดี: Long sensing distance allows flexible installation space. M12 connector enables quick replacement under heavy vibration; IP67 withstands dust and cooling water splashes.

หมายเหตุ:

1. Low trolley travel speed matches 10Hz switching frequency.
2. Stainless steel target plate preferred. For aluminum targets, calculate distance using reduction factor.
3. Keep large steel structures away from the sensing face to prevent false triggering.

กรณี 2: Horizontal Rough Positioning for AS/RS Stacker Cranes in Automated Warehouses

อุตสาหกรรม: คลังสินค้าอัจฉริยะ, ห้องเย็น

สารละลาย:

NCN100-F23-E2-V1 sensors are installed in segments along the stacker travel rail. When the stacker’s metal baffle passes the sensor, it provides a rough position presence signal, working together with encoders for position calibration.

การทำงาน: Confirm the stacker arrives at the storage location and trigger deceleration. Avoid failure of photoelectric sensors caused by dust and moisture.

ข้อจำกัด: Only rough positioning, not high-precision positioning; provides digital presence signal only, no distance measurement.

กรณี 3: Station Presence Detection for Heavy-Duty AGVs

อุตสาหกรรม: Factory heavy-load AGVs, mining material transfer vehicles

สารละลาย:

Sensors are mounted at ground stations, and metal target blocks are fitted on AGV side panels. When AGV enters the station and the target enters sensing range, the sensor outputs a presence signal for PLC to lock wheels and start loading/unloading.

ข้อดี: Long sensing distance permits larger docking tolerance and lowers navigation accuracy requirements. Resists workshop dust and oil contamination, more stable than photoelectric sensors.

ข้อจำกัด: Not for high-speed AGVs. 10Hz switching frequency may cause missed detection for fast-moving targets.

กรณี 4: Presence Detection for Heavy Transfer Trolleys in Steel & Cement Plants

อุตสาหกรรม: โลหะวิทยา, ปูนซีเมนต์, sintering plants

สารละลาย:

Sensors are mounted rail-side for sintering trolleys and steel billet transfer trolleys. The sensor detects when the trolley metal baffle arrives at unloading / loading station.

สภาพการทำงาน: High radiant heat, heavy dust and strong vibration. Sensor operating temperature -25~70℃ meets requirements. Large metal targets ensure stable detection.

เคล็ดลับการว่าจ้าง: Mass steel structures exist on site, metal clearance must be reserved to avoid constant false triggering by background metal.

กรณี 5: Position Monitoring for Large Hydraulic/Pneumatic Heavy-Duty Gates & Flaps

อุตสาหกรรม: การบำบัดน้ำเสีย, mining silo gates

สารละลาย:

One NCN100-F23-E2-V1 is fitted at fully-open and fully-closed positions of silo discharge gates respectively, to detect arrival of the metal actuator baffle. Position feedback is sent to PLC to confirm gate status and interlock upstream/downstream belt conveyors.

คุณสมบัติ: Slow gate movement perfectly matches low switching frequency. Remote sensor installation keeps it away from sediment and material impact.

กรณี 6: Trolley Limit Protection for Gantry Cranes in Container & Steel Yards

อุตสาหกรรม: พอร์ต, steel logistics yards

สารละลาย: Sensor used for travel limit protection of gantry crane trolley. Detects trolley approaching metal end stop to trigger pre-deceleration as secondary safety limit.

หมายเหตุ: It is only a position switch, NOT a SIL safety rated sensor. Cannot be used as sole safety protection; mechanical limit switch is recommended as backup.

📌 General Application Notes (Applicable to All Cases)

1. Target material reduction: Stainless steel target factor =1.0; aluminum =0.37. Effective distance drops greatly for aluminum targets, must be calculated in selection.
2. Movement speed constraint: Max switching frequency 10Hz. Only for limit and presence confirmation; strictly prohibited for high-speed counting.
3. การติดตั้ง: Non-flush mounting. Sensing face cannot be embedded into metal. Adequate metal clearance around sensor.
4. Power-up delay: Up to 90ms initialization time. PLC logic needs power-up delay to prevent false signals on startup.
5. Target plate size: Target area cannot be too small. Target must fully cover the sensor sensing face, otherwise unstable detection occurs.

Working Principle of Inductive Proximity Sensors

หลักการสำคัญ: Alternating Magnetic Field + Eddy Current Effect in Metal Conductors

Inductive proximity sensors detect metal objects only. Non-metals (พลาสติก, ไม้, กระจก, ยาง) cannot be sensed.

Internal Components

1. LC Oscillator Circuit (ม้วน + ตัวเก็บประจุ): Generates high-frequency alternating electromagnetic field radiating outward from the sensing face after power-on.
2. Demodulation & Comparator Circuit: ตรวจสอบความแปรผันของแอมพลิจูดของการสั่น
3. Output Driver Circuit: เอาท์พุททรานซิสเตอร์ (เอ็นพีเอ็น / พีเอ็นพี)
4. แหล่งจ่ายไฟ, indicator LEDs

ลำดับการดำเนินงานที่สมบูรณ์

1. After sensor power-up, the LC circuit starts oscillation. The coil emits high-frequency alternating magnetic field.
2. No metal target present: Little energy loss in magnetic field, oscillation is maintained. Circuit judges no target, output stays in original state.
3. Metal target enters magnetic sensing zone: Alternating magnetic field penetrates metal surface and induces eddy current inside metal via electromagnetic induction.
4. Eddy current generates reverse magnetic field counteracting the original coil field → energy of oscillator circuit is consumed and oscillation amplitude attenuates.
5. The detection circuit detects amplitude drop below threshold, confirms metal presence and toggles transistor output (NO contact closes / หน้าสัมผัส NC จะเปิดขึ้น), meanwhile the switching LED lights up.
6. Metal moves out of sensing zone: Eddy current disappears, magnetic field recovers and oscillation resumes, sensor output resets.

One-sentence summary: Coil generates alternating magnetic field; metal creates eddy current to consume magnetic energy; circuit identifies energy change and outputs switch signal.

ลักษณะสำคัญ (Referencing NCN100-F23-E2-V1)

1. ระยะการตรวจจับ & Material Reduction

Eddy current strength depends on metal conductivity and permeability:

Ferromagnetic metals (เหล็ก, สแตนเลส): Strong eddy current, long sensing distance (reduction factor≈1)

อลูมิเนียม, ทองแดง: Non-ferromagnetic, weaker eddy current, effective sensing distance greatly reduced (Al:0.37, Cu:0.35, matching previous parameters)

2. Flush / Non-Flush Mounting

Flush: Can be embedded into metal base; magnetic field concentrated on front face; shorter sensing range

Non-flush (NCN100 is this type): Cannot be embedded in metal; magnetic field diverges wider, ระยะการตรวจจับที่ยาวขึ้น, but side metal may cause false triggering

3. การสลับความถี่

Time is required for magnetic field build-up and eddy current decay, hence maximum response frequency. NCN100 only 10Hz, not for fast-moving workpieces.

4. ฮิสเทรีซีส

Trigger distance on approach is larger than reset distance on departure. วัตถุประสงค์: prevent signal chattering caused by mechanical vibration.

Simple Comparison vs Photoelectric Sensors

อุปนัย: Metal-only detection. Immune to dust, moisture and oil. Long-range models cost higher and subject to material reduction.

โฟโตอิเล็กทริค: Detects metal and non-metal. Prone to failure when lens contaminated by dust or water mist.

เสริม

⚠️ Inductive proximity sensors are NOT distance measuring sensors. They only provide a binary signal indicating whether metal enters the threshold distance, no numerical distance output.
