Dry and mercury wetted reed switches available 

Wide range of switch configurations - **1 Form A** , **2 Form A** , **1 Form B** and **1 Form C** 

For R.F. or high speed digital applications, 

**50** or **75 Ω** coaxial devices are available in the same small package 

## **3** , **5** or **12 V** coils are standard, with optional internal diode 

> e , or BC Additional build options are available 

- ° Many benefits compared to industry standard relays [ (see last page) 

## Please contact our technical department for supplementary RF data. 

The special high temperature plastic package will withstand the temperatures associated with Infra-red or vapor phase reflow soldering processes. A flexible inner encapsulant protects the sensitive glass/metal reed switch seals - this is a very big advantage over the more usual hard moulded package.

|Note1: Life Expectancy||
|The life of a reed relay depends upon the switch load and end of life criteria. For example, for an ‘end of life’ contact||
|resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx||
|1 x 109ops. At the maximum load (resistive), typical life is 1 x 107ops. In the event of abusive conditions, e.g. high currents||
|due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any||
|particular load condition.||



**Operating Voltages** 

Coil voltage - nominal Must operate voltage - maximum at 25°C Must release voltage - minimum at 25°C 3 V 2.25 V 0.3 V 5 V 3.75 V 0.5 V 12 V 9 V 1.2 V ~~ee~~ 

**Environmental Specification/Mechanical Characteristics** In the table below, the upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level. Please contact  sales@pickeringrelay.com  for assistance.

## **Similar Relays Comparison** 

The Series 200 is unique in the Pickering range of reed relays. Pickering do not manufacture another series of surface mount relays. 

## **Reed Relay Selection Tool** 

Because Pickering offer the largest range of high-quality reed relays, sometimes it can be difficult to find the right reed relay you require. That is why we created the Reed Relay Selector, this tool will help you narrow down our offering to get you the correct reed relay for your application.
