The Pickering Series 88 reed relay is a mercury-wetted device with a 2 Form A (normally open) contact configuration, designed for high-power switching applications up to 50 watts at 500 volts. It operates with a 12-volt coil and has a coil resistance of 750 ohms. The relay is encapsulated in a plastic package with an internal mu-metal magnetic shield, fits a 0.1 inch pin grid, and requires vertical mounting with the arrow on the package pointing upward. It shares the same footprint and pin configuration as the Series 80 dry reed relays, enabling PCB compatibility across switch types.
These ranges of reed relays are available with both dry and mercury wetted switches. They are available with 5, 12 and 24 volts coils, a particularly useful feature of the 5 volt dry devices is their ability to be driven directly from TTL, the coil requiring only 10mA of drive current. All units have an internal magnetic screen and can be supplied with built-in diode if required.
Standard coil voltages are 5, 12 and 24 volts. All relays are fitted with internal magnetic screen to avoid stray magnetic interaction between adjacent relays. Many special coil resistances are available, and relays can be designed to customers specific requirements. These Pickering relays fit straight onto P.C. boards with pins on the popular 0.1 inch grid. They are completely protected, being encapsulated in plastic cases. With these series you get the choice of three different dry reed switches and two mercury wetted switches in a range of configurations to cover all switching problems. See Switch Ratings in adjacent column.
The Series 80 and 85 are electrically similar ranges but with alternative pin configurations; these are shown overleaf. Their mercury wetted equivalents are prefixed 88 and 89 respectively..
