For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads or when ‘cold’ switching, typical life is expected to be greater than 1 x 108 ops. At higher voltages and 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 conditions. 1 pickeringrelay.com ISSUE 2.3 JAN 2022 Note1: Switching Voltage This high voltage rating is for RESISTIVE loads only. At these high voltages, even stray capacitance can generate very high current pulses, which can damage the contact plating causing welding of the reed switch. If there is capacitance in circuit, provision should be made to limit the surge, to within the current and power ratings of the relay. Specification High Voltage Mini-SIL/SIP Reed Relays – Series 131 Application Note: A characteristic of the switch used in this range is the contact resistance can increase over time if subjected to standoff voltages in the upper range of the specification. This does not affect the life expectancy but can result in contact resistances greater than 1 Ohm. In most high voltage applications this increase has no effect on performance but, in some mixed signal applications low and stable contact resistance is important. For this reason, Pickering offer both a low-level and a general-purpose option for all package types, the low-level parts have a reduced high voltage standoff and are tested for extended contact resistance stability as part of the production testing. The low-level versions have 131L at the start of the part number. For new applications or for further information please contact our Technical department. Operating Voltages Coil voltage - nominal Must operate voltage - maximum at 25°C Must release voltage - minimum at 25°C 3V 2.25 V 0.3 V 5V 3.75 V 0.5 V 12 V 9V 1.2 V 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.

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.
