2300 Series Multi-Pole Reed Relays
e Coto 2300 series is designed to oer the densest packaging available in a multi-
pole reed relay. e size and footprint of the 2300 series complement the 2200 & 2900
series relays. e 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 denes 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 is relay is polarity sensitive. Pin #3 MUST be positive.
Environmental Ratings:
