2300 SERIES MULTI-POLE REED RELAYS
2300 Series Multi-Pole Reed Relays
The Coto 2300 series is designed to offer the densest packaging available in a multi-
pole reed relay . The size and footprint of the 2300 series complement the 2200 & 2900
series relays . The 1 Form C model is constructed with individual switch capsules for
the normally open and magnetically biased normally closed contacts which are more
reliable than the spring actuated 1 Form C reed switches . Custom pin-outs as well as
custom designs are available to meet particular applications .

Consult factory for life expectancy at other switching loads . Resistance >0 .5Ω defines end of life or failure to open .
Break-before-make action on Form C Model 2341 is not guaranteed . Consult factory if break-before-make is required .
Electrostatic shield (2332 & 2341 only) is connected to pin #6 . Coaxial shield is connected to pins #6 and #7 .
This relay is polarity sensitive . Pin #3 MUST be positive .
