Small size Internal mu-metal magnetic screen One or two switches in a single package **Form A** (energise to make) or **Form B** (energise to break) configurations **3** , **5** , **12** or **24 V** coils with optional internal diode > ° Additional build options are available Po ## FP (see last page) Many benefits compared to industry standard relays > e Suitable for high power applications and in many cases, may be used as an alternative to mercury wetted reed relays Unusually for high power relays, the Series 114 feature sputtered ruthenium contacts instead of the more common electroplated rhodium or tungsten types. This also makes them suitable for low level or “dry” switching. They are able to switch a.c. mains voltages so are suitable for interfacing to larger electromechanical relays or contactors. It is important however, to suppress back EMFs from inductive loads. This is achievable by using an RC snubber, varistor or similar voltage limiting device. The range features an internal mu-metal screen to minimize problems that would otherwise be experienced due to magnetic interaction when they are closely stacked. Form A versions may be stacked side-by-side. Due to the fact that the Form B types feature an internal biasing magnet, a gap of 0.4 inches minimum should be left between adjacent relays. **==> picture [341 x 215] intentionally omitted <==** **----- Start of picture text -----**

~~TTEET PETE~~| |---| |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 109ops. At the maximum load (resistive), typical life is 10 x 107ops. 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 3 V 2.25 V 0.3 V 5 V 3.75 V 0.5 V 12 V 9 V 1.2 V 24 V 18 V 2.4 V ~~ee~~ **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.

Note3| When an internal diode is required, the suffix D is added to the part number as shown in the table. ## Note[2] : Capacitance across open switch The capacitance across the open switch was measured with other connections guarded. ## Note[3] : Capacitance values The value will depend upon on the mode of connection/guarding of unused terminals. Please contact technical sales for details. ## Note[4] : Insulation resistance Insulation resistance will reduce at higher temperatures.

**Important:** Where the optional internal diode is fitted or for all Form B types, the correct coil polarity must be observed, as shown by the + symbol on the schematics. Due to the presence of an internal biasing magnet, Form B relays have a higher level of magnetic interaction than Form A types. A space of 0.4 inches minimum should therefore be left between adjacent parts. pickeringrelay.com 4 Specification High Power Dry SIL/SIP Reed Relays – Series 114 ## **Similar Relays Comparison** If the Series 114 is unsuitable for your application, Pickering also manufactures another series of reed relays with similar characteristics, but in different package sizes. **==> picture [512 x 251] intentionally omitted <==** **----- Start of picture text -----**
