The Pickering Series 86 and 87 are high-sensitivity reed relays with a plastic encapsulated package and internal mu-metal magnetic screen, designed for through-hole mounting on a 0.1 inch pin grid. The 86-1-A-24/8 variant is a 1 Form A relay with a 24 V nominal coil voltage, rated for 10 watts at 200 V switching under dry contact conditions, and a maximum switch current of 1.2 A. The coil resistance is 6000 Ω. The relay includes an internal diode, as indicated by the suffix D in the part number. It is rated for a maximum operating temperature of 85 °C, extendable to 125 °C with adjusted coil drive voltage. The device supports up to 10^7 operations at maximum resistive load and must be operated with correct coil polarity when the diode is fitted. Pin configuration and mechanical dimensions are consistent with other Series 86 and 87 variants.
These ranges of reed relays are essentially the same as the dry Series 80 and 85 and the mercury wetted Series 88 and 89 but with coil resistances between 2 and 3 times higher. This feature is particularly useful when using large numbers of relays, to reduce overall current requirements and heating effects, or when the available coil drive power is restricted, for example, in battery operated equipment.
Many special resistances are available, and relays can be designed to customers specific requirements.
These Pickering reed relays fit straight onto P.C. boards with pins on 0.1 inch grid. They are completely protected, being encapsulated with plastic covers. All relays are fitted with internal magnetic screens to avoid stray magnetic interaction between adjacent relays.
The Series 86 and 87 are electrically identical ranges but offer alternative pin configurations. These are shown overleaf.
