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 .
