The Pickering Series 118 is a range of single-pole, single-throw reed relays designed for low-power applications requiring high packing density and minimal board space. The part 118-1-A-5/1 is a 5 V coil version with switch type 1, rated for 15 W switching and 1.0 A carry current, featuring a plastic package with internal mu-metal magnetic shielding and a footprint of 5.1 x 8.4 mm. It has an insulation resistance greater than 10^12 Ω, operates within a temperature range of -20 to +85 °C, and includes a typical operate time of 0.6 ms and release time of 0.35 ms. The part is not equipped with an internal diode, as indicated by the absence of the "/D" suffix.
The Pickering Series 118 is a range of very sensitive reed relays that are ideal for portable electronic instruments or other applications where low power consumption and a very small footprint is important. They have 5 volt coils with a resistance up to 2200 Ω and the option of an internal diode.
Two switch types are available. Switch type number 1 is better suited for general purpose applications. Switch type 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.
