3600 SERIES/LOW THERMAL EMF REED RELAYS
3600 Series Low Thermal EMF Reed Relays
e 3600 Series is ideally suited to the needs of Instrumentation, Data Acquisition,
and Process Control. e 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.
