Reed Switches
Reed Switches
Reed switches are available in a normally open or
normally closed configuration. The low amp switch is
suitable for connection to PLCs or other low current
devices. The high amp switch can be used to drive
sequencers, relays, coils, or other devices directly. Not
compatible with TTL level I.O. Logic (switch will work with
TTL level if wired backwards but LED will not light).

* Polarity is restricted for DC operation: (+) to Brown (-) to Blue
If these connections are reversed for TTL levels the contacts
will close, but the LED will not light. Connector versions are for
DC operation only.
** Exceeds temperature range for ET Series mechanical components.
