10 Watt High Density Reed Relays

All Pickering reed relays feature the highest quality instrumentation grade reed switches making them suitable for the most demanding applications. Internal mu-metal magnetic screens (optional on Series 103) allow very high packing density. Diodes are optional.

Pickering Series 112 Reed Relays

• 100% tested for dynamic contact resistance
SoftCenter construction extends lifetime
• Highest quality instrumentation grade switches

The Pickering Series 112 is a range of magnetically screened single-in-line reed relays that require a board area of only 0.15 inches (3.8mm.) by 0.4 inches (10mm.) while retaining the 10 Watts, 0.5 Amps rating associated with larger relays. This small footprint is achieved by mounting the reed switch diagonally within the package.

These relays require around one third the board area of the more usual 0.2 x 0.8 inch devices and the height of only 0.43 inches (11mm.) is suitable for high density card based systems such as VME, VXI, Compact PCI, and PXI. The high quality, sputtered ruthenium switch contacts also makes them ideal for Automatic Test
Equipment.

The Series 112 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance greater than 1012 ohms. The relay has an internal mumetal screen which totally eliminates the risk of magnetic interaction problems. An unscreened device mounted on this pitch would have an interaction figure of around 40 percent. Relays of this size without magnetic screening would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 112 have a typical interaction
figure of 5 percent.

3, 5 and 12 Volt coils are standard, with the option of an internal diode. 5 Volt coils have a resistance of 500 ohms and may be driven directly from TTL logic.
