Holding force with armature
GZZ (s = 0mm) 2)

2. That force produced when using plated
(chemical nickel) armature type GZZE 050
X00 A01
3. The forces will be reduced if other material
specification, thickness and surfaces are used,
or if the armature fails to make contact over
the full diameter of the magnet face.
4. The magnetic remanence can be reduced
by increasing the air gap. This can be achieved
by machining away an area of the armature
surface. But there will be corresponding
reduction in holding force.

20% at rated voltage). Adjust for armature weight

POWER CONSUMPTION (P20)

is listed with 250C coil temperature (decrease/HOT). The temperature

rise is limited to 600C to provide a low surface contact temperature.
the magnetic forces can therefore be increased with special coil winding
