About Magnets

DC-Powered Electromagnets

Position the face of these magnets in direct contact with a flat metal surface and turn on the power to create a magnetic hold. Magnets have wire leads that connect to a DC electromagnet power supply (sold separately). Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.

Magnets with spring-loaded release have a pin that pops up to separate the object and magnet when the power is turned off.

Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

DC-Powered Electromagnets with Parallel Poles

Parallel poles create a better magnetic hold on thinly painted, plated, or coated flat metal surfaces than other magnets. A terminal block on the magnet connects to a DC electromagnet power supply (sold separately). Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.

Plug-In Electromagnets

Position the face of these magnets in direct contact with a flat metal surface and plug in to create a magnetic hold. The plug contains a transformer that converts power from AC to DC, so no additional wiring or power source is needed. Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.

Air-Powered Magnetic Grippers

(All Components Sold Separately)

Connect these magnetic grippers to an air system to lift odd-shaped and perforated metal parts that often cause traditional vacuum cups to lose hold. Designed to work in any position, they only require one flat surface to securely grip parts. All have durable rare earth magnets that stay engaged, so they won’t drop parts in the event of air loss. Plus, unlike electromagnetic grippers, they do not need electric power to create a magnetic hold. Use these grippers in a variety of automated production lines and robotic pick-and-place systems.

Standard and heavy-load grippers have two air connections, one at each end, and a magnetic piston. One connection uses air to extend the piston and grip your part, while the other uses air to retract the piston and release the magnetic hold. All of these grippers have top and side mounting threads for attaching an optional mounting adapter that fits in tool arms commonly found in automation applications. Standard grippers with a stainless steel gripping surface withstand scrapes from parts with rough edges better than those with an aluminum gripping surface. Those with a proximity sensor signal when the magnetic piston is gripping or releasing a part, and uses that information to trigger other actions in your system. The sensors have a standard 4-pole micro M12 plug for electrical connections. Use heavy-load grippers for high temperatures when working near furnaces or near welding jobs.

Low-clearance grippers have one air connection that supplies a burst of air to release the magnetic hold. Those for destacking have a shallow magnetic field, so you can use them to lift and separate a top sheet from a stack of metal sheets.

Grippers with PNP sensors communicate proximity with a positive signal, while those with NPN sensors send a negative signal.

CE-marked grippers meet stringent European Union safety standards.

Friction rings absorb impact as grippers take hold to protect your parts from damage.

Note: Capacities listed are based on lifting flat metal that has a clean, smooth surface. If used on dirty, oily, thin, or curved surfaces, the capacities will be reduced.

Warning: Never use to lift people or items over people.

Use robot tool mounts with threaded connections to mount grippers to robot arms with ISO 31.5, 40, 50, or 63 mounting patterns. If you don't see your robot model number listed, measure the bolt circle diameter to determine mounting compatibility.

Gripping Adapters

V-Notch Gripping Adapter

Rectangular Gripping Adapter

Add V-notch gripping adapters to grippers when you need a better hold on round parts, such as bars and tubes. Use rectangular gripping adapters with grippers for grasping uneven or curved parts that don’t have one flat surface that’s large enough to secure a hold—they’re designed to contact two separate flat surfaces.

Gripper-Surface Protectors

(All Components Sold Separately)

Gripper-Surface Protector

Gripper-surface protectors guard gripper surfaces from damage. Use them when handling hard or rough parts, such as metal sheets in hot-forming processes. If your gripper has friction rings, they are usually removed when using these protectors.
