Suitable for high density instrumentation applications such as A.T.E. switching matrices or multiplexers 

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when additional relays, stacked each side, are themselves operated. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required.

The Series 117 is suitable for most instrumentation applications. If a higher rating is required, the Series 115, which is rated at up to 20 Watts, 1.0 A should be considered. The relay footprint and pin configurations of the Series 115 are identical but the case height increases to 0.61 inches (15.5 mm). Please see further down the Series 117 datasheet for a similar relay comparison table.

The reed switch in the Series 117 is suitable for low level or 'cold' switching. In accordance with Pickering convention, this switch is referred to as type number 2. There is no general purpose switch (type number 1) currently available in this series, but the type 2 is suitable for all applications if it is used within its specified ratings. This means that high inrush currents, particularly caused by capacitive loads must be avoided. 

## Note[1] : 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 2.5 x 10[8] ops. At the maximum load (resistive), typical life is 10 x 10[6] ops. 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<br>5 V|2.25 V<br>3.75 V|0.3 V<br>0.5 V|



## **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.

When an internal diode is required, the suffix D is added to the part number as shown in the table. 

## Note[2] : Switch to Coil Capacitance 

Due to the asymmetrical internal construction of the relay, the capacitance to the coil from one switch connection is approximately half the capacitance of the other switch connection, pin 3 is lower. In some applications this feature may be used to advantage for example, in a multiplexer where it is desirable to minimize the capacitance of the common connection to maximize bandwidth. 

## Note[3] : Capacitance across open switch 

The capacitance across the open switch was measured with other connections guarded. 

## Note[4] : Insulation resistance 

Insulation resistance will reduce at higher temperatures. For more information on temperature effects click here, or contact Pickering for more in depth guidance.
