SMC Vacuum Ejector, 1.5 mm nozzle, -91 kPa 56 L/min, ZH series

This vacuum ejector is a Compact pneumatic unit designed to generate suction for automation and handling tasks in industrial environments. It integrates a two‑stage ejector with pilot‑operated valves and an LED pressure display, operating from a 12 to 24V DC supply and intended for use with compressed Air within defined pressure limits.

• 83 L/min maximum suction flow delivers high throughput
• -91 kPa maximum vacuum pressure enables strong pick‑up force
• 1.5mm nozzle diameter provides focused suction performance
• 8mm exhaust port reduces installation time with one‑touch fitting
• Operates between +5 and +50 °C for common factory conditions
• Built‑in silencer lowers exhaust noise to 69 dB during operation

• Suitable for pick‑and‑place of light components in electronics assembly
• Ideal for vacuum gripping on conveyor systems in mechanical lines
• Used for tray and sheet handling in automated packaging
• Can be used for component transfer in electrical panel assembly

It functions within a supply pressure window of 0.3 to 0.6 MPa, with a standard recommendation of 0.4 MPa.

A digital pressure switch with a 3½‑digit LED display and selectable set range allows precise setting in 0.1 kPa increments and PNP output signalling.

The unit uses 12 to 24V DC power with PNP open‑collector outputs for general and valve control, and includes short‑circuit protection and residual voltage under 2V at rated load.

Air passes through a 30 μm element and a suction filter area of 510 mm²
