Design & Performance Advantages

The ZH20DSA body ported configuration delivers a compact profile with significant dimensional reductions compared to previous generations: 11% shorter overall length (6.7 mm reduction), 25% lower port height (9.1 mm reduction), and 39% smaller enclosed volume. The lightweight molded resin construction reduces unit weight by up to 74% (65.1 g lighter), minimizing moment of inertia in mobile and robotic applications while maintaining superior vacuum performance.

Mounting Flexibility

Four mounting options accommodate diverse system integration requirements: direct mounting for manifold integration, standard bracket mounting for space-constrained installations, L-bracket mounting for angular configurations, and DIN rail mounting for modular pneumatic control panels. Optional silencer and standard bracket accessories are available exclusively for body ported type units, enabling acoustic optimization and standardized panel mounting.

Application Suitability

Optimized for electronic parts and small to medium precision components up to 100 g, the ZH20DSA supports both ejector and vacuum pump system architectures. The modular design enables integration with optional digital vacuum switches, solenoid valves, and pressure gauges through unitized valve configurations, supporting adaptable manifold applications with combined functions and self-holding capabilities.

Key Benefits for Manufacturing Engineers

• Compact Footprint: Reduced dimensions enable space-efficient integration in confined panel layouts and automated assembly stations
• Lightweight Construction: Minimized weight supports dynamic motion control in pick-and-place and robotic handling systems
• High Flow Capacity: 90 L/min suction flow handles larger pad arrays and faster cycle times compared to smaller nozzle variants
• Modular Integration: Compatible with SMC pneumatic control components for complete vacuum circuit solutions
• Standardized Connectivity: One-touch fittings and screw-in port options simplify installation and field modifications

Regulatory & System Compatibility

The ZH20DSA operates at standard industrial supply pressure (0.45 MPa) and integrates seamlessly with SMC pneumatic infrastructure, including suction filters, pressure switches, release valves, and variable throttle controls. Cartridge-type nozzle elements enable quick field replacement without system shutdown, reducing maintenance downtime in high-throughput production environments.

Why Choose the ZH20DSA

Engineers and procurement specialists select the SMC ZH20DSA for applications demanding high suction flow with minimal package size. Its proven performance in electronics manufacturing, automotive assembly, and precision packaging applications, combined with SMC's global support network and documented reliability standards, makes it the benchmark choice for OEM equipment builders and system integrators requiring industrial-grade vacuum generation with design flexibility.
