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. 

The range features an internal mu-metal screen to eliminate problems that would otherwise be experienced due to magnetic 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 drive and 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 DC. 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. For information on the recommended spacing between high voltage parts, please see 7 page 3.

## Note[1] : Life Expectancy 

Relay life depends upon switch load and end of life criteria. 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 10[9] ops. At the maximum load (resistive), typical life is 1 x 10[7] ops. In abusive conditions (e.g. high capacitive inrush current) this figure reduces considerably. Pickering can perform life testing with any load conditions..

## **Washing Guidelines** 

Pickering do not make any specific recommendations on washing reed relays, due to the large number of factors in cleaning processes, however we do have suggestions on best practices. Click  here  for more information. 

## **Extended Operating Temperature Range** 

With the copper coil winding wire having a resistance/temperature coefficient of approximately 0.4% per °C, changes in temperature 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 guide or contact  techsales@pickeringrelay.com. 

## **Recommended Spacing for High Voltage Parts** 

When working with high voltages, the recommended space between pins is 2 mm per 1 kV stand-off voltage. For example, the 5 kV version of the 104 should have a gap of 10 mm between the pins.

**10 Key Benef its** of Pickering Reed Relays 

Series **104** 

|**Key Benef it**|**Pickering Reed Relays**|**Typical Industry Reed Relays**||
|---|---|---|---|
|1<br>Instrumentation Grade<br>Reed Switches|Instrumentation Grade Reed Switches<br>with vacuum sputtered Ruthenium plating<br>to ensure stable, long life up to 5x10E9<br>operations.|Often low grade Reed Switches with<br>electroplated Rhodium plating resulting in<br>higher, less stable contact resistance.||
|2<br>Formerless Coil<br>Construction|Formerless coil construction increases the<br>coil winding volume, maximizing magnetic<br>effi ciency, allowing the use of less sensitive<br>reed switches resulting in optimal switching<br>action and extended lifetime at operational<br>extremes.|Use of bobbins decreases the coil winding<br>volume, resulting in having less magnetic<br>drive and a need to use more sensitive reed<br>switches which are inherently less stable<br>with greatly reduced restoring forces.|Pickeringformer-less coil<br>Typical industrycoil<br>wound on bobbin:|
|3<br>Magnetic<br>Screening|Mu-metal magnetic screening (either external<br>or internal), enables ultra-high PCB side-by-<br>side packing densities with minimal magnetic<br>interaction, saving signifi cant cost and space.<br>Pickering Mu-Metal magnetic screen -<br>interaction approx. 5%|Lower cost reed relays have minimal or no<br>magnetic screening, resulting in magnetic<br>interaction issues causing changes in<br>operating and release voltages, timing and<br>contact resistance, causing switches to not<br>operate at their nominal voltages.Typical<br>industry screen - interaction approx. 30%|X-Ray of Pickering<br>mu-metal<br>magnetic screen<br>X-Ray of typical<br>industry<br>magnetic screen|
|4<br>**SoftCenter**™<br>Technology|**SoftCenter**™technology, provides maximum<br>cushioned protection of the reed switch,<br>minimising internal lifetime stresses and<br>extending the working life and contact<br>stability.|Transfer moulded reed relays (produced<br>using high temperature/pressure), result<br>in signifi cant stresses to the glass reed<br>switch which can cause the switch blades to<br>defl ect or misalign leading to changes in the<br>operating characteristics, contact resistance<br>stability and operating lifetime.|Pickering<br>Typical industry<br>soft center<br>thermo-setting<br>protectionof = hard mouldedprotection<br>the reed switch<br>of thereed switch|
|5<br>100% Dynamic<br>Testing|100% testing for all operating parameters<br>including dynamic contact wave-shape<br>analysis with full data scrutiny to maintain<br>consistency.|Simple DC testing or just batch testing which<br>may result in non-operational devices being<br>supplied.|Coil Voltage<br>Contact Resistance<br>Dynamic Contact Resistance Test<br>Operate<br>Release|
|6<br>100% Inspection<br>at Every Stage of<br>Manufacturing|Inspection at every stage of manufacturing<br>maintaining high levels of quality.|Often limited batch inspection.||

|9<br>Custom Reed Relays|Our reed relays can be customized easily,<br>e.g. special pin confi gurations, enhanced<br>specifi cations, non-standard coil or resistance<br>fi gures, special life testing, low capacitance,<br>and more.|Limited ability to customize.||
|10<br>Product Longevity|Pickering are committed to product longevity;<br>our reed relays are manufactured and<br>supported for more than 25 years from<br>introduction, typically much longer.|Most other manufacturers discontinue parts<br>when they reach a low sales threshold;<br>costing purchasing and R&D a great deal of<br>unnecessary time and money to redesign<br>and maintain supply.|900<br><OngeyS|
