Pickering Series 120 reed relay

The Pickering Series 120 is a range of single-pole reed relays that require a board area of only 4 x 4 mm. Two switch types are available: a general-purpose sputtered ruthenium switch rated for up to 20 W, 1 A and a low-level sputtered ruthenium switch rated at 10 W, 0.5 A.

The products are the same reed switches as used in other Pickering Electronics ranges but are orientated vertically within the package, enabling the high density. The small size of the package does not allow an internal diode.

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction.

The device has pins on a 2 mm square pitch. SMD and through-hole connectors will allow the relays to be stacked in either a row or in a matrix on a 4 mm pitch.
