The Pickering Series 87 reed relay is a 2 Form A, dry contact relay for PCB mounting with a 0.1 inch pin grid. It has a 24 V nominal coil voltage and 6000 Ω coil resistance. The relay switches up to 10 W at 200 V with a maximum contact current of 1.2 A. Its typical life is 1 × 10^7 operations at maximum load and 1 × 10^8 at low loads. The encapsulated plastic package includes an internal mu-metal magnetic shield to prevent crosstalk. Operating temperature range is -20 °C to +85 °C, extendable to +125 °C with increased coil voltage. No internal diode is present, as denoted by the absence of the 'D' suffix. Orientation bar is printed on top, indicating upright mounting.
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.
