The Series 85 reed relay is a general-purpose device with a 1 Form B (energize to break) switch configuration, available with a 24 V coil. It is encapsulated in a plastic package with an internal mu-metal magnetic screen and mounts on a 0.1 inch grid PCB footprint. The relay is designed for dry switch operation with a maximum switching rating of 10 watts at 200 V and a maximum carry current of 1.2 A. The coil resistance is 3000 Ω, and the relay does not include an internal diode. All members of the series feature the same pinout for compatibility with mercury-wetted Series 89 relays. The device is intended for through-hole mounting and operates with standard coil voltage options of 5, 12, or 24 V.
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..
