The Pickering Series 118 is a range of very sensitive reed relays that are ideal for portable electronic instruments or other test applications where low power consumption and a very small footprint is important. The reed relays have 3 volt and 5 volt coils with a resistance up to 2200 Ohms and the option of an internal diode.

Two reed switch types are available. Switch type number 1 is better suited for general purpose applications, while Switch type number 2 is better suited to low level or 'cold' switching.

Both types feature high quality, instrumentation grade switch contacts and require a board area of only 0.2 x 0.33 inches (5.1 x 8.4 mm).

These relays feature internal mu-metal magnetic screens. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Relays of this size without
magnetic screening would be totally unsuitable for applications where dense packing is required.

Initially, single pole versions only are available in this range but double pole versions will follow in the future.
