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 109 ops. At the maximum load (resistive), typical life is 1 x 107 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.

10 Key Benefits of Pickering Reed Relays
Pickering Reed Relays
Typical Industry Reed Relays
Instrumentation Grade Reed Switches
with vacuum sputtered Ruthenium
plating to ensure stable, long life up to
5x10E9 operations.
Often low grade Reed Switches with
electroplated Rhodium plating resulting
in higher, less stable contact resistance.
22
Formerless Coil
Construction
Formerless coil construction increases
the coil winding volume, maximizing
magnetic efficiency, allowing the use of
less sensitive reed switches resulting in
optimal switching action and extended
lifetime at operational extremes.
Use of bobbins decreases the coil
winding volume, resulting in having
less magnetic drive and a need to use
more sensitive reed switches which
are inherently less stable with greatly
reduced restoring forces.
3
Magnetic Screening
Mu-metal magnetic screening (either
external or internal), enables ultra-high
PCB side-by-side packing densities with
minimal magnetic interaction, saving
significant cost and space. Pickering
Mu-Metal magnetic screen - interaction
approx. 5%
Lower cost reed relays have minimal
or no magnetic screening, resulting in
magnetic interaction issues causing
changes in operating and release
voltages, timing and contact resistance,
causing switches to not operate at their
nominal voltages. Typical industry
screen - interaction approx. 30%
4
SoftCenter™ technology, provides
maximum cushioned protection of the
reed switch, minimising internal lifetime
stresses and extending the working life
and contact stability.
Transfer moulded reed relays (produced
using high temperature/pressure),
result in significant stresses to the glass
reed switch which can cause the switch
blades to deflect or misalign leading to
changes in the operating characteristics,
contact resistance stability and operating
lifetime.
100% testing for all operating
parameters including dynamic contact
wave-shape analysis with full data
scrutiny to maintain consistency.
Simple dc testing or just batch testing
which may result in non-operational
devices being supplied.

Product Longevity
Limited ability to customize.
Pickering are committed to product
longevity; our reed relays are
manufactured and supported for
more than 25 years from introduction,
typically much longer.
Most other manufacturers discontinue
parts when they reach a low sales
threshold; costing purchasing and R&D
a great deal of unnecessary time and
money to redesign and maintain supply.
