7000 SERIES/HIGH RELIABILITY REED RELAYS

7000 Series High Reliability Reed Relays

e 7000 Series is ideally suited to the needs of Instrumentation, Data Acquisition,

Process Control, Telecommunications and General Purpose requirements. e speci-

cation tables allow you to select the appropriate relay for your particular application.

ese models are specically designed for high quality and reliability with versatile

switching capabilities and contact forms. If your requirements dier, please consult

your local representative or Coto’s Factory to discuss a custom reed relay.
