PLAY 20X4 NAAMS SH - 81401725
The Magswitch PLAY 20x4 SH magnetic gripper utilizes magnets arranged in a linear array to extend the footprint of the magnetic field. The SH version also adds the capability of handling high temperature parts. Custom pole shoes can be added to the PLAY 20x4 SH magnetic gripper to increase holding force on parts that are not flat. The extended footprint provides stability when handling long parts. The compact size of the PLAY 20x4 SH makes it a great choice for handling high temperature parts on a robot or in a welding fixture.
*Pole shoes are required for operation and are included in the package.

- SWL (Safe Working Load) = Maximum Force5 / Safety Factor (≥5)
- 1Determined in laboratory environment on 2” thick SAE1018 steel with surface roughness 63 micro inches with optimized pole shoes. Many factors contribute to the actual breakaway force and safe working load in each application. Consult a Magswitch Applications Engineer and test the Magswitch in each application before deployment.
- 2All data applies to unit with flat pole shoes (8800172) installed.
- 3Tested and determined with two SAE1018 steel sheets L=200mm W=200mm Thickness=4mm.
- 4Values may vary by +/- 5%.
- 5Maximum forces listed above are not safe lifting forces. Designer must take into account safety factor when specifying tool. Magswitch recommends SWL = 5:1 for most applications.
