ISSUE 1.2 JAN 2022 (see last page) Pico SIL/SIP Reed Relays Series 111 pickeringrelay.com — Including 1.5 GHz coaxial types — Stacks on 0.15 x 0.40 inches pitch — Highest quality instrumentation grade switches — Mu-metal magnetic screening — Two package styles - mu-metal package or plastic package with internal mu-metal magnetic screen — They take up the minimum of board area, conserving board space — Includes 111RF, a 50 Ω coaxial device suitable for use up to 1.5 GHz — Insulation resistance >1012 Ω — 3 or 5 V coils with or without internal diode — Additional build options are available — Many benefits compared to industry standard relays Requiring around one third the board area of the more usual 0.2 x 0.8 inch devices these relays are ideal for high density applications. Two package styles are available: The type 111 is encapsulated in a mu-metal can. The coaxial version, type 111RF, is also available in this package style. The type 111P is encapsulated in a plastic package and features an internal mu-metal screen. An internal diode is an option in both types. Magnetic screening is essential to avoid magnetic interaction problems. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when two additional relays, stacked one each side, are themselves operated. An unscreened device mounted on this pitch would have an interaction figure of around 40%. Relays of this size would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 111 have an interaction figure of around 1 percent.

1 A 10 W 0.5 A 0.5 A 170 108 0.5 ms 0.2 ms General purpose 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 due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any particular load condition. 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 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.

10 Key Benef its of Pickering Reed Relays

Key Benef it Pickering Reed Relays Typical Industry Reed Relays Instrumentation Grade Reed Switches 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. 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. 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% SoftCenter™ Technology 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% Dynamic Testing 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. 100% Inspection at Every Stage of Manufacturing Inspection at every stage of manufacturing maintaining high levels of quality. Often limited batch inspection. 100% Thermal Cycling Stress testing of the manufacturing processes, from -20°C to +85°C to -20°C, repeated 3 times. Rarely included resulting in field failures. Flexible Manufacturing Process Flexible manufacturing processes allow quick-turn manufacturing of small batches. Mass production: Usually large batch sizes and with no quick-turn manufacturing. Custom Reed Relays 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. Limited ability to customize. Product Longevity 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.
