ثالثا. M12 5-Pin Pin Assignment (A-coded)
- Pin1: +24في العاصمة (Power Positive)
- Pin2: OUT2 (رقمي / Analogue Output)
- Pin3: 0V GND (Power Negative)
- Pin4: OUT1 / IO-Link communication line
- Pin5: Not assigned
> Under IO-Link mode, Pin4 serves as main communication channel; under SIO mode, Pin4 acts as digital switching output.
- التطبيقات النموذجية
Pure water cooling circuits, machine tool cooling systems, washing equipment, auxiliary hydraulic cooling, neutral fluid monitoring in food industry, flow totalisation measurement.
- اختيار & إرشادات الاستبدال
- If medium temperature measurement is required → Upgrade to 8036872 SFAW-32T-TG12-E-PNLK-PNVBA-M12
- For NPT/Rc thread connections, modify the TGxx segment in model code
- If only two digital outputs are needed without analogue signal, select simplified output variants to reduce cost
- Same housing higher flow variant: SFAW-100 (5～100 L/min)
- Important Risk Warnings
Reverse fluid flow is strictly prohibited, flow direction must be P1→P2; reverse flow will damage the measuring element
Media must be free of solid particles; filter installation upstream is recommended
Maintain straight pipe sections before and after sensor for measurement accuracy (upstream ≥5×DN, downstream ≥3×DN)
Digital output and analogue output cannot be activated simultaneously on OUT2; mode selection must be set via menu

ثالثا. Clearance Requirement for Electrical Connection
M12×1 A-coded 5-pin straight connector extends horizontally outwards from the side of the display
Recommended minimum clearance ≥35 mm on connector side for easy plug mating and removal
Display supports ±90° rotation for flexible readout orientation in cabinet layout
- Mandatory Straight Pipe Requirements for Accuracy
Upstream (inlet side) straight pipe: ≥5×DN15 ≈75 mm
Downstream (outlet side) straight pipe: ≥3×DN15 ≈45 mm
Do not install immediately adjacent to elbows, tees, ball valves or reducers;
Flow direction P1→P2 only; reverse installation forbidden.

Net weight: 400 ز
- Layout Design Notes
- Process ports are G1/2 internal thread; reserve wrench clearance when fitting male thread adapters
- The display is rotatable; reserve minimum 8 mm clearance on all sides if cabinet cutout is planned
- Max medium temperature reaches 90℃; arrange proper heat resistance for surrounding cables and seals
