3600 Series/Low Thermal EMF Reed Relays
Low Thermal EMF Reed Relays
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 Recorders. If your requirements differ from the selection
options, please consult Coto’s Factory to discuss a custom reed relay.

Dot stamped on top of relay refers to pin #1 location
Grid = .1"x.1" (2.54mm x 2.54mm)
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 resistance are specified at 25°C.
These values vary by approximately 0.4% / °C
as the ambient temperature varies.
Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s
Consult factory for life expectancy at other switching loads.
Model 3660: Reed switch between pins #9 & #10 is not low
thermal and is tied in common with the electrostatic shield.
Consists of 56V Zener diode and 1N4148 diode in series,
connected in parallel with coil.
Model 3650: Reed switch between pins #3 & #4 is not low
thermal and is not tied in common with the electrostatic shield.
