Tungsten plated contacts ensure a long and reliable life 

**5** , **12** , and **24 V** coils with optional internal diode 

Note:  Package Types 1 and 2 have the same body style yet different pin positions

The Series 67 and 68 ranges of high voltage reed relays have similar specifications to the established Series 60/65 and 62/63 but are constructed using a leadframe in a Single-in-Line format and feature former-less coils which enables a smaller package than is usual for this type of device. 

The unusual package style allows some interesting stacking possibilities (see adjacent photo) when used to construct high density multiplexers or matrices. 

Other voltages can be supplied to special order as can variations in the lead length of the Series 68 type. 

## **Switch Ratings** 

|1 Form A (energize to make)|1 Form C (changeover)|
|---|---|
|Stand-off 5 kV, switching up to 3.5 kV<br>Stand-off 8 kV, switching up to 6 kV (Series 67 only)<br>Stand-off 10 kV, switching up to 7.5 kV|Stand-off 5 kV, switching up to 2.5 kV|

At these high voltages, even stray capacitance can generate very high current pulses, which can damage the contact plating causing welding of the reed switch. If there is capacitance in circuit, provision should be made to limit the surge, to within the current and power ratings of the relay. 

## Note[2] : Life Expectancy 

The life of a reed relay depends upon the switch load and the end of life criteria. For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads with the current less than 1 mA, or when ‘cold’ switching, typical life is expected to be greater than 1 x 10[8] ops. At higher voltages and up to the maximum 50 W load (resistive), typical life is 1 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 conditions.

## **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.
