Description : Powerful electro-magnets in a range of sizes and voltage for holding/ energizing or releasing / de-energized. Ideal for use in machine mechanisms, door guard locking and applications with remote hold / release requirements. Optimum performance when used with Erich armature plates (available separately) but suitable for holding any smooth ferrous surface of adequate thickness. Electrical connection by free leads. Coils are continuously rated at the specified supply voltage, a.c. Or d.c. Zinc plated magnet body and armature plates. Magnets mounted on rear face by center tapped holes or 3 tapped holes on PCD. Remanence (approx. 5% of holding force) may be reduced by fitting non magnetic shim between magnet and armature.
