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

2.5 x 108 ops. At the maximum load (resistive), typical life is 1 x 106 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.

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.
