ORD211REED SWITCH

ORD211General 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 loadsless than 24 V. The contacts are sealed within the glass tube with inert gas to maintain contactreliability.

Features

(1) Reed contacts are hermetically sealed within a glass tube with inert gas and do not receive anyinfluence from the external atmospheric environment.

(2) Quick response

(3) The structure comprises an operating system and electrical circuits coaxially. Reed switchesare 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 switchingoperation and long life.

(6) With a permanent magnet installed, reed switches economically and easily become proximityswitches.
