## 2300 Series Multi-Pole Reed Relays 

## Multi-Pole Reed Relays 

The Coto 2300 series is designed to offer the densest packaging available in a multipole 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 pinouts 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 

Sd Smallest Multipole Relay: 0.056 sq. inches/pole (3 pole relay) Sd Up to 3 Form A or 2 Form C Contacts Hermetically Sealed Contacts ry. Long Life / High ReliabilityMagnetically Shielding Steel Shell Sd Optional Electrostatic Shield (on most models)

## Notes: 

- 1 Consult factory for life expectancy at other switching loads. 

- 2 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. 

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[o] C.  These values vary by approximately 0.4% / °C as the ambient temperature varies. Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s
