112-1-A-12/2D

Series 112 Single-in-Line SIL/SIP Reed Relays — Switching 10 W, 0.5 A — 1 Form A stacks on 0.15 x 0.40 inches pitch — Highest quality, sputtered ruthenium instrumentation grade reed switches — Ideal for high density card based systems and automatic test equipment — Plastic package with internal mu-metal magnetic screen — They take up the minimum of board area, conserving board space — Insulation resistance >1012 Ω Package Type 1 — 3, 5 or 12 V coils with or without internal diode —  Additional build options are available — Many benefits compared to industry standard relays (see last page) Suitable for high density card based systems such as VME, VXI, Compact PCI, and PXI. The high quality, sputtered ruthenium switch contacts also makes them ideal for Automatic Test Equipment. The 5 Volt coil version has a resistance of 500 ohms and may be driven directly from TTL logic. The Series 112 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 ohms. The relay has an internal mu-metal screen which totally eliminates the risk of magnetic interaction problems. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 112 have a typical interaction figure of 5 percent.

It is also a good general purpose “hot” switch as long as the maximum switching current specification is observed. There is no Switch number 1 available in this range at present. 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 1 x 109 ops. At the maximum load (resistive), typical life is 1 x 106 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. 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.
