Many benefits compared to industry standard relays 

The Series 104 reed relays are ideal for such applications as transformer or cable testing or any other automatic test equipment where high voltages are involved. 

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 to magnetic interaction when they are closely stacked. 

Four types of dry switches are available, capable of standing-off 1.5, 2, 3 or 4kV d.c. The 3kV & 4kV versions have an increased clearance between the switch and coil pins to accommodate the higher voltage. Even higher voltage ratings are available to special order, please contact our sales office for further information. 

Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at 1500 volts d.c. minimum stand-off, 500 volts d.c. switching at up to 50 watts.

High Voltage SIL/SIP Reed Relays – Series 104 

## **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. 

Operating Temperature Range -20 ºC to +85 ºC Storage Temperature Range -35 ºC to +100 ºC Shock Resistance 50 g Vibration Resistance (10 - 2000 Hz) 20 g Soldering Temperature (max) (10 s max) 270 ºC Washability (Proper drying process is recommended) Fully Sealed ~~———~~

|2<br>Formerless Coil<br>Construction<br>2|Formerless coil construction increases<br>the coil winding volume, maximizing<br>magnetic efficiency, allowing the use of<br>less sensitive reed switches resulting in<br>optimal switching action and extended<br>lifetime at operational extremes.|Use of bobbins decreases the coil<br>winding volume, resulting in having<br>less magnetic drive and a need to use<br>more sensitive reed switches which<br>are inherently less stable with greatly<br>reduced restoring forces.|“Ty<br>mitt)<br>wing,<br>ae<br>Pickering former-less coil<br>Typical industry coil<br>wound on bobbin|
|Magnetic Screening<br>3|Mu-metal magnetic screening (either<br>external or internal), enables ultra-high<br>PCB side-by-side packing densities with<br>minimal magnetic interaction, saving<br>significant cost and space.Pickering<br>Mu-Metal magnetic screen - interaction<br>approx. 5%|Lower cost reed relays have minimal<br>or no magnetic screening, resulting in<br>magnetic interaction issues causing<br>changes in operating and release<br>voltages, timing and contact resistance,<br>causing switches to not operate at their<br>nominal voltages.Typical industry<br>screen - interaction approx. 30%|X-Ray of Pickering<br>mu-metal<br>magnetic screen<br>X-Ray of typical<br>industry<br>magnetic screen|
|**SoftCenter**™<br>Technology<br>4|**SoftCenter**™technology, provides<br>maximum cushioned protection of the<br>reed switch, minimising internal lifetime<br>stresses and extending the working life<br>and contact stability.|Transfer moulded reed relays (produced<br>using high temperature/pressure),<br>result in significant stresses to the glass<br>reed switch which can cause the switch<br>blades to deflect or misalign leading to<br>changes in the operating characteristics,<br>contact resistance stability and operating<br>lifetime.|Pickering<br>Typical industry<br>soft center<br>thermo-setting<br>protection of<br>hard moulded protection<br>the reed switch<br>ofthe reed switch|

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