• Household appliances

Dimensions (mm)

O R D 229

High breakdown voltage



The ORD229 is a single-contact, high power reed switch (70VA AC or 50W

DC) designed for high breakdown voltages up to 600V DC.

High breakdown voltage



Hermetically sealed within a glass tube with inert gas,

reed contacts are not influenced by the external

atmospheric environment.



Quick response



Comprising of operating parts and electrical parts

arranged coaxially, reed switches are suited to high-

frequency applications.



Compact and light weight.



Superior corrosion resistance and wear resistance of the

contacts assures stable switching operation and long life.



Economically and easily becomes a proximity switch

when paired with a magnet.
