2300 Series/Microminiature Reed Relays M ULTIPOLE MICROMINIATURE REED RELAYS The Coto 2300 series was designed to offer the densest packaging available in a multipole reed relay. The size and footprint of the 2300 series compliment the 2200 and 2900 series microminiature 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. Special designs include 1 Form B, 2 Form B, latching, and high voltage relays. 2300 SERIES FEATURE u u u u u u Smallest Multipole Relay: 0.056 sq. inches/pole (3 pole relay) Up to 3 Form A or 2 Form C Contacts Hermetically Sealed Contacts Long Life / High Reliability Magnetically Shielding Steel Shell Optional Electrostatic Shield (on most models) Dimensions in Inches (Millimeters) Bottom View 8 Catch Us on the Web! www.cotorelay.com E-Mail us: [email protected] 2300 Series/Microminiature Reed Relays Model Number Parameters 3,5 2341 2333 3 Form A 1 Form C 2342 2 Form C Test Conditions Units 2332 2 Form A +/- 10%, 25° C Must Operate by Must Release by VDC Ω VDC - Max.

Release time is specified with a zener diode suppression circuit consisting of a 20 V zener diode in series with a 1N4148, connected in parallel with the coil. 3 Break-before-make action on Form C Model 2341 is not guaranteed. Consult factory if break-before-make is required. 4 Electrostatic shield is connected to pin #6. Coaxial shield is connected to pins #6 and #7. 5 This relay is polarity sensitive. Pin #3 MUST be positive. 2 Environmental Ratings Storage Temp: -35 °C to + 100 °C; Operating Temp: -20 °C to + 85 °C Solder Temp: 270°C max; 10 sec. max The operate and release voltage and the coil resistance are specified at 25oC. These values vary by approximately 0.4% / °C as the ambient temperature varies.
