Vacuum generators and suction cups are integral to industrial automation pick and place systems as a gripping solution. Supporting products include: vacuum filters, regulators, and vacuum sensors.
SMC suction cups are modular allowing for custom configuration of a multitude of sizes, shapes, materials, and mounting adapters. Options include: non-marking types, FDA compliant, various cup shapes, ball-joint connections, and buffers to ensure a perfect fit for every application.
SMC's array of vacuum generators, also referred to as ejectors, have variations that include single ejector unit, manifold, inline, and generator/cup in one.
Suction Cups are the critical point of contact for pick and place applications for handling corrugated cardboard, metal or glass sheets, food processing and packaging, and even bag opening tasks. They are designed in a wide range of diameters ranging from 0.8mm to 200mm for tiny objects to heavy-duty applications. SMC's standard cup shapes include: flat, thin flat, bellows, deep, oval, and oval flat. Suction cup materials are: Silicone, NBR, urethane, FKM, mark-free, and FDA compliant food grade materials. Installation options can be specified on either spring loaded buffers or threaded stems. Special application cups include: integrated with vacuum generator, with check valve, and in porous materials.
Vacuum Generators create industrial vacuum at the application's point of use utilizing the venturi effect and fluid flow from compressed air or gases. They are compact and light weight units designed for end-of-arm tooling (EOAT) on robotic arms or end effectors generating suction gripping force at the point of use while minimizing inertia. Vacuum levels as low as -27 inHG (-93 kPA) can be attained with multi-stage generators with suction flow greater than 7 SCFM (200 L/min). They can be configured into manifolds or mounted as individual units with options including: energy savings, compact, multi-stage, point-of-use, high speed release and integrated generator with suction cups.
Vacuum Filters protect vacuum generators and other vacuum equipment from contaminants and other small particles to maintain trouble-free pick and place operations. The filters are light weight and available in compact and inline types with replacement filter elements.
Vacuum Sensors are electrical devices that provide switch output signals for set points to monitor vacuum pressure in machine automation, leak testing equipment, and pick and place applications. They are also installed in process gas and liquid applications for the semiconductor and food processing industries. Electronic versions are available with multi-line and multi-color displays ranging in protection levels from the standard IP40 to IP67 and IO-Link compatible. They meet standards: UL/CSA, CE, and are RoHS compliant.
Vacuum Regulators control and stabilize the level of vacuum by regulating the flow of atmosphere introduced into its chamber by manually adjusting a diaphragm valve or by electro/pneumatic stepless control via a proportional electric signal. The E/P units have an integrated monitor and are rated IP65.
The vacuum unit is a plug and play integration kit that is compatible with several collaborative robots. The design is compact and lightweight with many cup configurations including 1 cup, 2 cup or 4 cup options. The cup options include variations of shapes, materials, and sizes. One of the notable options include the FDA compliant cup material. The unit includes connector, mounting flange, protective cover, and integrated vacuum unit.
The vacuum saving valve (ZP2V) is installed between the suction cup and vacuum source and will constrict when it is not holding a workpiece, only allowing suction air to flow through a small fixed orifice, acting as a flow control device. When the suction cup is holding a part, the valve will expand increasing flow to the suction cup. This feature will save time by not having to reconfigure or remove idle suction cups when not being used for different tasks.
High Vacuum for semiconductor wafer manufacturing requires precision equipment to exhaust air from the process chamber and to supply atmospheric to restore the chanber to atmospheric pressure.
Slit Valves (XGTP) allow access to transfer the wafer into and out of the process chamber.
Angle and Inline Valves (XL, XM, XY) are used to exhaust the chamber.
Supply Valves (XSA, XVD) are used to supply gases to the chamber.
Non-contact suction cups (XT661) utilize the Bernoulli principle for picking up parts where direct contact is not feasible. The design makes it possible for picking up porous, uneven and serrated surfaced objects.
XT661's design averts deforming or distorting the shape of fragile and non-rigid workpieces such as: foil, thin sheets, paper, and printed circuit boards.

With no moving parts, air conveyors (ZH-X185, X-226, X-249, X338) will create vacuum to transfer bulk materials like grain or pellets; they can also be used to remove smoke, debris, and fine particles from the work area. By reversing the air flow, they become air blow off units.
The special purpose SP Adsorption Plate adsorbs workpieces and holds them in position without leaving wrinkles, air bubbles or marks, making this an ideal addition for production lines thin sheets, glass, substrates, and soft workpieces. The ZCUK special cylinder bundles suction and lifting forces by integrating a hollow cylinder rod with a suction cup interface to save time on set-up. Bore sizes available up to 32mm and stroke lengths up to 50mm.
The AMJ water separator for vacuum removes water droplets sucked into the vacuum line during work operations to protect upstream vacuum generators and pumps.
