REED SWITCH
ORD213
Super Ultraminiature
J2R0012-38-22
GENERAL DESCRIPTION
The ORD213 is a small single-contact reed switch designed for general control of low-level
loads less than 24 V. The reed contacts are sealed within the glass tube within inert gas to maintain
contact reliability.
FEATURES
(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 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.
