Supporting electromagnets These devices are designed for supporting or gripping ferromagnetic parts. The maximum retaining force is obtained by contact with flat mild steel parts, with a surface area equal to or greater than the attraction surface, and with a sufficient thickness (equal to at least 1/8 th of the diameter ofthe electromagnet). Any gap, no matter how small, will noticeably reduce this maximum force. Supply voltage: 24 Vdc Protection index: IP 40 Thermal class: B (130 °C) Stock switching max. VF dimensions (mm) weight no.
