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.  Download Datasheet

1Consult factory for life expectancy at other switching loads. Resistance >0.5Ω defines end of life or failure to open.
2Break-before-make action on Form C Model 2341 is not guaranteed. Consult factory if break-before-make is required.
3Electrostatic shield (2332 & 2341 only) is connected to pin #6. Coaxial shield is connected to pins #6 and #7.
4This relay is polarity sensitive. Pin #3 MUST be positive.
