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 .
2300 Series Features
u Smallest Multi-pole Relay: 0 .056 sq . inches/pole (3 pole relay) u Up to 3 Form A or 2 Form C Contacts u Hermetically Sealed Contacts u Long Life / High Reliability u Magnetically Shielding Steel Shell u Optional Electrostatic Shield (on models 2332 & 2341) u RoHS compliant

Notes: 1 Consult factory for life expectancy at other switching loads . Resistance >0 .5Ω defines end of life or failure to open . 2 Break-before-make action on Form C Model 2341 is not guaranteed . Consult factory if break-before-make is required . 3 Electrostatic shield (2332 & 2341 only) is connected to pin #6 . Coaxial shield is connected to pins #6 and #7 . 4 This relay is polarity sensitive . Pin #3 MUST be positive .
