5W + 1.5GHz RF 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.

The Pickering Series 111 is a range of magnetically screened single-in-line reed relays that stack on 0.15 inches by 0.4 inches pitch. They have an identical footprint to the Series 110 and 112 but the height is reduced to only 0.26 inches (6.6mm).

The switch rating of 5 Watts is adequate for most instrumentation applications. If a higher power rating is required, please look at our Series 110 or 112 which have a 10 Watts rating and an identical pin-out. The range also includes the type 111RF, a 50 ohms coaxial device suitable for use up to 1.5 GHz.

These relays require around one third the board area of the more usual 0.2 x 0.8 inch devices and are ideal for high density applications.
Two package styles are available:

The type 111 is encapsulated in a mu-metal can. The coaxial version, type 111RF, is also available in this
package style.

The type 111P is encapsulated in a plastic package and features an internal mu-metal screen. An internal diode isan option in both types.

Magnetic screening is essential to avoid magnetic interaction problems. Interaction is usually measured as a percentage increase in the voltage required to operate a relay when two additional relays, stacked one each side, are themselves operated. An unscreened device mounted on this pitch would have an interaction figure of around 40%. Relays of this size would therefore be totally unsuitable for applications where dense packing is required. Pickering Series 111 have an interaction figure of around 1 percent.
