**COTO CLASSIC™ 2300 MULTI-POLE REED RELAYS** 

## **1 Description** 

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 & 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.

## **General Notes:** 

1. On Model 2332 and 2341, shielded versions are available. Electrostatic shield is connected to pin #6. Coaxial shield is connected to pins #6 and #7. 

2. Break-before-make action on Form C Model 2341 is not guaranteed. Consult factory if break-before-make is required. 

3. Consult factory for life expectancy at other switch loads. Resistance > 0.5Ω defines end of life or failure to open. 

4. Model 2341 is polarity sensitive. Pin #3 MUST be positive. 

## **Environmental Ratings:** 

Storage Temp: -35ºC to +100[º] C; Operating Temp: -20[º] C to +85[º] C Vibration: 20 G's to 2000 Hz; Shock: 50 G's 

All electrical parameters measured at 25[º] C unless otherwise specified.

## **8 Relay Processing Notes** 

## **8.1 Soldering** 

Relays can be soldered by hand or by wave solder processing. Coto Technology recommends the maximum wave solder temperature (measured at the relay leads) as 270°C for 10 seconds. Temperature and time in excess of the recommended levels may result in damage to the relay. All our through-hole relays are compatible with either SAC alloy or eutectic soldering process. 

## **8.2 Cleaning** 

2300 is designed and manufactured to provide an adequate seal from external conditions. However, caution must be taken during the cleaning process not to expose the relays to conditions that will allow moisture to permeate into the package. Caution should be taken with dwell time between reflow and cleaning, high pressure spraying, and time in cleaning solvent/aqueous solutions, as these cleaning process parameters can contribute to moisture permeation. Board level bake out may be required after wash to remove moisture that has been introduced during cleaning operations. 

## **8.3 Relay Storage** 

Relay parametric specifications are specified at 25°C and 40% RH. Reduced relay performance may result if storage or use environments significantly exceed these conditions. If high insulation resistance is required, Coto Technology recommends that relay storage, processing, and use environments are adequate to achieve the desired results. Relays should be stored in similar environmental conditions as other high-reliability active and passive electronic components. Proper storage of relays is also important to maintain solderability over an extended period of time. 

## **8.4 Handling** 

Relays should be handled with care. Dropping or mishandling relays may result in damage that can contribute to a direct failure or, even worse, a latent field failure. If relays are dropped, Coto Technology recommends that they should be discarded. 

Coto Technology does not recommend use of ultrasonic activated equipment with relays. The use of ultrasonic equipment may change the characteristics of the relay and can contribute to failure.
