🛠️ Application Fields

Пищевое оборудование, линии заполнения, фармацевтическое оборудование, washdown stations, metal target detection under frequent CIP/SIP high-pressure cleaning and high-humidity high-temperature conditions; suitable for level detection, metal workpiece presence check and cylinder position feedback.

⚠️ Выбор & Рекомендации по установке

1. Скрытый монтаж: The sensor face can be recessed into metal brackets; the surrounding metal of the mounting surface will not reduce the sensing distance.
2. Корпус из нержавеющей стали + Рейтинг IP69K, resistant to alkaline cleaners and hot high-pressure washdown; NOT suitable for long-term immersion in concentrated strong acids.
3. Reduction factor <1 for non-ferrous metals; sensing distance is significantly reduced for aluminium/copper targets, allow sufficient margin during selection.
4. Switching frequency only 100 Гц, not applicable for high-speed counting.
5. M12 4-pin male plug wiring: Коричневый(+24В), Синий(0В), Черный(Выходной сигнал PNP), Белый (unused).

🧩 Replacement References

Та же серия: IIT202 (8 Расстояние срабатывания мм, M30 hygienic type)

Отечественные альтернативы: M30 flush stainless steel PNP NO inductive proximity sensor; проверять 14 mm sensing distance and 0~100 ℃ temperature range.

📋 Troubleshooting Checklist

1. Нет сигнала: Check if 24V power is supplied to brown and blue wires. Reverse polarity will not damage the sensor but causes no operation.
2. No output when target approaches: Check target material (distance reduction for Al/Cu); verify flush fit with mounting metal.
3. Ложное срабатывание: Metal debris on sensing face; poor shield grounding of cable.
4. Intermittent failure after hot washdown: Inspect plug sealing and ensure connector watertightness.

ИФМ IIT205 (IIB3014BBPKG/V4A/US-104) Случаи применения

> Core selection criteria: Hygienic M30 flush, IP68/IP69K, 316л(V4A) нержавеющая сталь, 0~100 ℃, compatible with CIP/SIP high-pressure cleaning, ПНП НЕТ, 14 mm flush sensing distance; 100 Hz switching frequency, for static/low-speed position detection only, not for high-speed counting.

Случай 1: Beverage Filling Line – Spool Position Feedback for Filling Valves (Beer / Mineral Water / Dairy)

Рабочее состояние: Filling valves undergo CIP hot water + alkaline detergent high-pressure spray, wide temperature cycling from 0~95 ℃, humid mist environment.

Функция: Mounted on hygienic pneumatic valve bodies to detect metal spool rod position. PLC confirms valve fully open / fully closed to prevent empty filling or overflow.

Why IIT205

1. IP69K withstands 80~100 bar high-pressure spray and Ecolab food-grade cleaners; 316L stainless steel housing without hygienic dead zones, flush installation prevents product residue buildup.
2. 0~100 ℃ withstands thermal shock; no signal drift during CIP hot cleaning.
3. 14 mm sensing distance accommodates spool stroke tolerance; flush mounting ensures valve body metal does not reduce detection range.

Примечания: For stainless steel spools, reduction factor =0.7, reserve sufficient effective sensing distance; only for position confirmation, not high-speed pulse counting.

Случай 2: Metal Baffle / Metal Float Level Detection on Aseptic Tanks for Dairy Products

Рабочее состояние: Aseptic tanks for fresh milk/yogurt, periodic SIP steam sterilization, humid brackets on tank exterior, acid/alkaline cleaning cycles.

Функция: Detect metal float to trigger high/low level alarms, start/stop feeding to prevent overflow or dry-run of tank.

Ключевые моменты: Sensor flush-recessed into stainless steel bracket, no hygienic dead corners; PEEK sensing face resistant to hot steam; M12 plug for quick disassembly during equipment cleaning.

Случай 3: Metal Tray Presence Detection for Food Packaging Machines (Meat / Ready Meal Packaging Lines)

Рабочее состояние: Conveying stainless steel trays continuously; hot water washdown between stations, high humidity and splashing food debris.

Функция: Verify stainless steel tray arrival; trigger sealing/vacuum forming upon detection; lock mold closing if no tray present to protect tooling.

Selection Benefits: Flush installation prevents damage from tray scraping; stainless steel housing resists food cleaning fluid corrosion; multi-directional yellow LED for status inspection after washdown.

Случай 4: Hygienic Cylinder End-position Detection for Pharmaceutical Equipment (Таблетка / Powder Production Lines)

Рабочее состояние: GMP cleanroom, actuators require periodic high-temperature disinfection and detergent rinsing; no grooves allowed to trap contaminants in clean areas.

Функция: Installed at the end of hygienic cylinders to detect metal stop block on piston, feedback extend/retract end-position signal for interlocking of subsequent processes.

Ключевые моменты: Gold-plated contacts for stable operation in humid clean environments; еда & pharmaceutical hygienic compliance; M12 4-pin plug for fast spare part replacement.

Случай 5: Metal Workpiece / Fixture Presence Confirmation for Meat Processing Cutting Lines

Рабочее состояние: High humidity, heavy foam and alkaline degreaser high-pressure washdown, wide ambient temperature fluctuation.

Функция: Detect presence of stainless steel work fixture; lock cutting blade if fixture not in position to avoid collision and implement safety interlock.

Ограничения: For aluminium fixtures, sensing distance reduced to 0.4 раз; sufficient margin must be reserved during selection; not suitable for high-speed reciprocating motion.

Случай 6: Metal Baking Tray Detection at Bakery Line Discharge

Рабочее состояние: Oven outlet, high ambient temperature up to nearly 100 ℃, oil-contaminated trays, high-pressure hot water cleaning per shift.

Функция: Detect stainless steel baking trays arriving at unloading station to start/stop conveyor belt.

Преимущества: Wide temperature range 0~100 ℃, oven residual heat will not damage sensor; IP69K allows direct washdown of grease; stainless steel housing resistant to oil corrosion.

❌ Non-suitable Applications (Pitfall Reminder)

1. Высокоскоростной подсчет, high-speed dynamic metal target detection: только 100 Hz switching frequency, pulse loss occurs at high speed.
2. Long-term immersion in concentrated strong acids: only resistant to weak acid/alkaline rinsing, not continuous concentrated acid soaking.
3. Thin copper foil or thin aluminium sheet: heavy reduction of sensing distance, prone to misjudgement.
4. Installed near high-power inverters with strong magnetic/electromagnetic interference; shielded grounding required separately.

Общая установка & Руководство по вводу в эксплуатацию (Применимо ко всем случаям)

1. Flush-recess into metal bracket, sensor head flush with metal surface.
2. Preferred target material: carbon steel, followed by 304/316 нержавеющая сталь; calculate effective sensing distance in advance for aluminium/copper targets.
3. Use matching hygienic watertight M12 connectors; connector area is the highest failure point during washdown.
4. Perform CIP cleaning test after installation, check LED status to confirm no intermittent false triggering.
