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.
