7000 Series/High Reliability Reed Relays
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 specification tables allow you to select the appropri-
ate 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.

refers to pin #1 location
(See following pages for schematic
diagrams and coil data.)
Notes:
1
Consult factory for life expectancy at other switching
loads.
2
Optional coil suppression diode Pin #1 is +.

Hg Content: Form A, 0.04 grams per capsule; Form C,
0.072 grams per capsule.
Environmental Ratings:
Storage Temp: -35°C to
+100°C;
Operating Temp: -20°C to
+85°C
Solder Temp: 270°C max; 10 sec. max
The operate and release voltage and the coil resis-
tance are specified at 25°C. These values vary by
approximately 0.4% / °C as the ambient temper-
ature varies.
Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s
