🛠️ Application Fields

Machines alimentaires, lignes de remplissage, équipement pharmaceutique, 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.

⚠️ Sélection & Directives d'installation

Montage encastré: The sensor face can be recessed into metal brackets; the surrounding metal of the mounting surface will not reduce the sensing distance.
Boîtier en acier inoxydable + Indice IP69K, resistant to alkaline cleaners and hot high-pressure washdown; NOT suitable for long-term immersion in concentrated strong acids.
Reduction factor <1 for non-ferrous metals; sensing distance is significantly reduced for aluminium/copper targets, allow sufficient margin during selection.
Switching frequency only 100 Hz, not applicable for high-speed counting.
M12 4-pin male plug wiring: Brun(+24V), Bleu(0V), Noir(Sortie de signal PNP), Blanc (unused).

🧩 Replacement References

Même série: IIT202 (8 mm distance de détection, M30 hygienic type)

Alternatives nationales: M30 flush stainless steel PNP NO inductive proximity sensor; verify 14 mm sensing distance and 0~100 ℃ temperature range.

📋 Troubleshooting Checklist

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

IFM IIT205 (IIB3014BBPKG/V4A/US-104) Cas de candidature

> Critères de sélection de base: Hygienic M30 flush, IP68/IP69K, 316L(V4A) acier inoxydable, 0~100 ℃, compatible with CIP/SIP high-pressure cleaning, PNP NON, 14 mm flush sensing distance; 100 Hz switching frequency, for static/low-speed position detection only, not for high-speed counting.

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

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

Fonction: 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

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.
0~100 ℃ withstands thermal shock; no signal drift during CIP hot cleaning.
14 mm sensing distance accommodates spool stroke tolerance; flush mounting ensures valve body metal does not reduce detection range.

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

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

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

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

Points clés: 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.

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

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

Fonction: 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.

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

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

Fonction: 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.

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

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

État de fonctionnement: Humidité élevée, heavy foam and alkaline degreaser high-pressure washdown, wide ambient temperature fluctuation.

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

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

Cas 6: Metal Baking Tray Detection at Bakery Line Discharge

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

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

Avantages: 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)

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

General Installation & Directives de mise en service (Applicable à tous les cas)

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