Series 104 High Voltage SIL/SIP Reed Relays — Up to 4 kV stand-off NEW Package Type — Stacking on 0.25 Inches pitch 3 — Small size 4 — Internal mu-metal magnetic screen — One or two switches in a single package — 1 Form A, 2 Form A & 1 Form B configurations — Dry and mercury wetted switches available — 5 V, 12 V or 24 V Coils with optional internal diode — Ideal for transformer or cable testing —  Additional build options are available including many pin configurations — Many benefits compared to industry standard relays (see last page) 1 2 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.

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.

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.

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. 1 Instrumentation Grade Reed Switches SoftCenter™ Technology 5 100% Dynamic Testing X-Ray of Pickering mu-metal magnetic screen X-Ray of typical industry magnetic screen Dynamic Contact Resistance Test Operate Contact Resistance Key Benefit Release 6 100% Inspection at Every Stage of Manufacturing 7 Inspection at every stage of manufacturing maintaining high levels of quality.

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. o n g v it e o n g v it e y 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.
