Reed Relays 2300 Series


	Multipole 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 and 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. Special designs include 1 Form B, 2 Form B, latching, and high voltage relays.

	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 most models)

Notes: ¹Consult factory for life expectancy at other switching loads. ²Consists of 56V Zener diode and 1N4148 diode in series, connected in parallel with coil. ³Break-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.




		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 25^oC. These values vary by approximately 0.4% / °C as the ambient temperature varies. Vibration: 20 G's to 2000 Hz; Shock: 50 G's
