REED SWITCH
ORD311
Super Ultra Miniature Long Life
n GENERAL DESCRIPTION
The ORD311 is a small single-contact reed switch designed for general control of medium
level loads less than 100 V. The contacts are sealed within the glass tube with inert gas to maintain
contact reliability.
n FEATURES
(1) Reed switches 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 the operating parts and electrical circuits arranged coaxially. Reed
switches are suited to applications in radio frequency operation.
(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.
