The 3600 Series is ideally suited to the needs of Instrumentation, Data
Acquisition, and Process Control. The specification tables allow you to
select the appropriate relay for your particular application. Recommended
for use in Scanners, Multiplexers and Digital or Analog Multipoint Record-
ers. If your requirements differ from the selection options, please consult
Coto’s Factory to discuss a custom reed relay. Refer to page 41 for
Thermal EMF test methods.
3600 SERIES FEATURES
u Low Thermal EMF: < 5 µV through < 0.5 µV with 50 nV stability.
u Patented Low Thermal Design. Patent #4,084,142.
u Low power coils to ensure low thermal EMF.

The operate and release voltage and the
coil resistance are specified at 25°C.
These values vary by approximately 0.4%/°C
as the ambient temperature varies.
