Non-standard sizes can be customized with a minimum thickness of 4MM. Labels may be changed during production; please disregard any label variations. Precautions: For electromagnets to achieve maximum suction, the following conditions must be met: 1. The object to be attracted must have good magnetic permeability. 2. Use the correct power supply and operate at the rated voltage. 3. The object to be attracted must be flat and clean. 4. The object must be equal to or larger than the surface area of the magnet. 5. The object must be at least 8mm thick. (Reduced thickness results in reduced suction force.) 6. The object must be in direct contact with the magnet surface; no gaps or intervening materials are allowed. Failure to meet any of these conditions will result in reduced suction force, not maximum performance. If you require a different model, please refer to the model table below: | Model | D1 (mm) | D2 (mm) | H (mm) | M | Power (W) | Suction (KG) | |--------|---------|---------|-------|----|-----------|--------------| | 10/10 | 10 | 4 | 10 | 2 | 1 | 0.3 | | 13/27 | 13 | 5 | 27 | 3 | 1 | 1 | | 13/30 | 13 | 5 | 30 | 3 | 1 | 1 | | 20/15 | 20 | 8 | 15 | 4 | 2 | 2.5 | | 25/11 | 25 | 10 | 11 | 4 | 2 | 5 | | 25/20 | 25 | 12 | 20 | 4 | 2 | 5 | | 30/22 | 30 | 12 | 22 | 4 | 3 | 10 | | 30/25 | 30 | 12 | 25 | 4 | 3 | 12 | | 34/18 | 34 | 16 | 18 | 4 | 3 | 18 | | 34/25 | 34 | 16 | 25 | 5 | 3.5 | 20 | | 36/38 | 36 | 38 | - | 5 | 25 | - | | 40/20 | 40 | 18 | 20 | 5 | 3.5 | 25 | | 40/25 | 40 | 18 | 25 | 5 | 4 | 30 | | 49/21 | 49 | 23 | 21 | 6 | 5 | 40 | | 50/27 | 50 | 23 | 27 | 6 | 6 | 50 | | 50/30 | 50 | 23 | 30 | 6 | 7 | - |
