Many benefits compared to industry standard relays

Requiring around one third the board area of the more usual 0.2 x 0.8 inch devices these relays 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 is an

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.
