• Control equipment

• Communication equipment

• Measurement equipment

• Household appliances

Dimensions (mm)

O R D 211

Ultra-miniature



The ORD211 is a small single-contact reed switch designed for general

control of low-level loads less than 24V. The contacts are sealed within

the glass tube with inert gas to maintain contact reliability.

Ultra-miniature



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.
