 Additional build options are available including many pin configurations
 Many benefits compared to industry standard relays (see last page)The Series 104 reed relays are ideal for mixed signal semiconductor testers, cable testing, monitoring photovoltaic
efficiency, EVs & charge point testing, mining gas analysis, medical electronics, in-circuit test equipment, high voltage
instrumentation, and much more.
Where mains voltages are switched, for example to control and isolate S.C.R. or triac gates, they are an ideal choice.
The range features an internal mu-metal screen to eliminate problems that would otherwise be experienced due tomagnetic interaction when they are closely stacked.
There is an option for an electrostatic shield between the switch and the coil to help minimise noise between the coil driveand high voltage circuits.
Where extended operating temperature ranges are required, options are designed to work from -40 °C to +125 °C, or custom
versions up to +150 °C.
Five types of dry switches are available, capable of standing-off 1.5, 2, 3, 4 or 5 kV d.c. The 1.5 kV and 2 kV versions are rated
to switch up to 1000 VDC, for 3 kV, 4 kV and 5 kV versions, under certain conditions, this can be extended to 1500 VDC. The
3, 4 & 5 kV versions also have an increased clearance between the switch and coil pins to accommodate the higher voltage.
Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at
1500 V d.c. minimum stand-off, 500 V d.c. switching at up to 50 W.

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 applications where a higher or lower operating temperature range is required, the 104HT range has been designed tomaintain optimum performance from -40 °C to +125 °C.
Standard Operating Temperature Range-20 ºC to +85 ºC

Extended Operating Temperature Range
With the copper coil winding wire having a resistance/temperature coefficient of approximately 0.4% per °C, changes intemperature will result in changes in operating voltage. A standard reed relay is designed to have optimum performance
up to the maximum operating temperature of +85 °C, the 104HT range has increased coil drive to ensure the same
performance up to 125 °C, and with certain considerations, up to +150 °C. For more information, see our Temperature guideor contact techsales@pickeringrelay.com.

High Voltage SIL/SIP Reed Relays – Series 104

10 Key Benefits of Pickering Reed Relays
Pickering Reed Relays

Typical Industry Reed Relays

1
Instrumentation Grade
Reed Switches

Instrumentation Grade Reed Switcheswith vacuum sputtered Ruthenium
plating to ensure stable, long life up to
5x10E9 operations.

Often low grade Reed Switches withelectroplated Rhodium plating resulting
in higher, less stable contact resistance.

22
Formerless CoilConstruction

Formerless coil construction increases
the coil winding volume, maximizing
magnetic efficiency, allowing the use ofless sensitive reed switches resulting in
optimal switching action and extended
lifetime at operational extremes.

Use of bobbins decreases the coilwinding 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 withminimal 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 inmagnetic interaction issues causingchanges in operating and releasevoltages, timing and contact resistance,
causing switches to not operate at theirnominal voltages. Typical industry
screen - interaction approx. 30%

4SoftCenter™ technology, provides
maximum cushioned protection of thereed switch, minimising internal lifetimestresses and extending the working lifeand 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 tochanges 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.

Often limited batch inspection.

Stress testing of the manufacturing
processes, from -20 °C to +85 °C to-20 °C, repeated 3 times.

Rarely included resulting in field failures.

Product Longevity

Limited ability to customize.

Pickering are committed to productlongevity; our reed relays are
manufactured and supported formore than 25 years from introduction,
typically much longer.

Most other manufacturers discontinueparts when they reach a low sales
threshold; costing purchasing and R&D
a great deal of unnecessary time andmoney to redesign and maintain supply.

o n g v iteo n g v itey

Our reed relays can be customized
easily, e.g. special pin configurations,enhanced specifications, non-standard
coil or resistance figures, special life
testing, low capacitance, and more.
