E2R0011-37-21 ORD211 REED SWITCH REED SWITCH ORD211 General Purpose Ultraminiature (Low-level Load 24 V Max.) GENERAL DESCRIPTION The ORD211 is a small single-contact reed switch designed for general control of low-level loads less than 24 V. The contacts are sealed within the glass tube with inert gas to mainatin 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. 3 (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. External Dimensions (Unit:mm) MAX f2.0 f0.4 MAX 10.0 35.7 0.3 APPLICATIONS OF REED SWITCHES 1.
