Many benefits compared to industry standard relays

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 5 V coil version has a resistance of

500 Ω and may be driven directly from TTL logic.

The Series 112 is encapsulated in a plastic package using a very high resistivity resin to achieve an insulation resistance

greater than 1012 Ω.

The relay has an internal mu-metal 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%. 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%.
