The ORD229 is a single-contact reed switch designed for high breakdown voltage of 600 VDC
and high power of AC 70 VA and DC 50 W. The contacts are sealed within the glass tube with
inert gas to maintain contact reliability.
(1) Reed contacts are hermetically sealed within a glass tube with inert gas and do not receive
any influence from the external atmospheric environment.
(2) Quick response
(3) The structure comprises an operating system and electrical circuits coaxially. Reed switches
are suited to applications in radio frequency.
(4) Reed switches are compact and light weight.
(5) Superior corrosion resistance and wear resistance of the contacts assures stable switching
operation and long life.
(6) With a permanent magnet installed, reed switches economically and easily become
proximity switches.
