7000 SERIES/HIGH RELIABILITY REED RELAYS
7000 Series High Reliability Reed Relays
The 7000 Series is ideally suited to the needs of Instrumentation, Data Acquisition,
Process Control, Telecommunications and General Purpose requirements. The speci-
fication tables allow you to select the appropriate relay for your particular application.
These models are specifically designed for high quality and reliability with versatile
switching capabilities and contact forms. If your requirements differ, please consult
your local representative or Coto’s Factory to discuss a custom reed relay.
