The 7000 Series is ideally suited to the needs of Instrumentation, Data
Acquisition, Process Control, Telecommunications and General Purpose
requirements. The specification 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.

Note s:
4 These relays contain bias magnets. Correct coil polarity must be observed.
5 Coil suppression diode is required for proper operation. Correct coil polarity must be observed.
6 Break before make not guaranteed.
7 Dot stamped on top of relay refers to pin #1 location. E-pin indicates Electrostatic shield pin. Unused pins omitted.
Pin numbers for reference only.
8 All models with Hg wet contacts are position sensitive, must be mounted within 30o of vertical plane. See schematic.
9 Model #7003-5193 represents a complete part number.
