> Under IO-Link mode, Pin4 serves as main communication channel; under SIO mode, Pin4 acts as digital switching output.

1. 일반적인 응용 분야

Pure water cooling circuits, machine tool cooling systems, washing equipment, auxiliary hydraulic cooling, neutral fluid monitoring in food industry, flow totalisation measurement.

1. 선택 & 교체 지침
2. If medium temperature measurement is required → Upgrade to 8036872 SFAW-32T-TG12-E-PNLK-PNVBA-M12
3. For NPT/Rc thread connections, modify the TGxx segment in model code
4. If only two digital outputs are needed without analogue signal, select simplified output variants to reduce cost
5. Same housing higher flow variant: SFAW-100 (5～100 L/min)
6. 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

파티 SFAW-32-TG12-E-PNLK-PNVBA-M12 (부품 번호. 8036871) 설치 치수

> SFAW-32 (without temperature) and SFAW-32T (with temperature) share identical outer dimensions; TG12 = G1/2 internal thread version

1. Key Overall Dimensions (단위: mm)
2. Centre-to-centre distance of process ports (pipe mounting length)

L = 73.2 mm (P1 inlet G1/2 internal thread ↔ P2 outlet G1/2 internal thread)

2. Valve body width (excluding display): 50 mm
3. Maximum overall height (valve bottom to top of display): 92 mm
4. Maximum overall depth (rear valve surface to display buttons): 61.2 mm
5. Process thread specification: Both ends G1/2 internal thread (TG12)
6. Bracket Mounting Hole Layout (for optional mounting bracket)

> Mounting holes arranged in rectangle: 50 × 35 mm, fixed with 4 × M5 나사.

III. 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

1. 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.

1. 무게

순중량: 400 g

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