Lignes directrices de sélection

1. Vacuum Matching: 90% vacuum is suitable for picking workpieces with good air tightness such as metal and hard plastic. For highly permeable workpieces, select larger nozzle size or higher flow models.
2. Nozzle Diameter Selection:

1.0mm (10): Low flow & low air consumption, for small and light workpieces

1.2mm (12): Medium flow, universal versatility

1.4mm (14): Haut débit, for medium-large and heavy workpieces

3. Solenoid Valve Type:

Tapez S (Caroline du Nord): Vacuum maintained when power off, for high safety requirement scenarios

Type V (NON): Vacuum released when power off, for fast workpiece release

4. Type de montage:

Standalone mounting: LEMAX90X__S/V (dual M8 interface)

Manifold mounting: LEMAX90X__SC14 (single M8 interface), combinable with multiple modules

5. Control Interface: Dual M8 allows independent vacuum and blow-off control; single M8 is controlled via internal logic.

Recommended Alternative Solutions

1. Upgrade Solution: LEMAX+ series (par exemple. LEMAX+90X14S) with higher flow and advanced ASC technology, suitable for high-speed automated production lines.
2. Economy Solution: LEM series (par exemple. LEM90X14S) with ASR (Air Saving Regulator), ~40% energy saving and cost-effective.
3. IO-Link Solution: LEMAXIO series (par exemple. LEMAXIO90X14S) supporting IO-Link communication for remote monitoring and parameter configuration, ideal for Industry 4.0 applications.
4. High-Flow Solution: For higher vacuum flow, choose 2.0mm or 2.5mm nozzle models such as LEMAX90X20S.
