TYPICAL APPLICATIONS
NF relays are widely acceptable in appli-
cations where small size and high sensi-
tivity are required.
Such applications include: Electronic
equipment, Household applications,
Alarm systems, Office machines, Com-
munication equipment, Measuring equip-
ment, Remote control systems, General
control circuits, Machine tools, Industrial
machinery, etc.
