" 9y f . " 9y f j2r0013-38-21 the ORD219 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. (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.
