The smallest footprint Reed Relay ever is to be showcased at Semicon Korea 2018

Pickering Electronics, an innovator and manufacturer of high-quality Reed Relays, plan to showcase the world’s highest density Reed Relay at Semicon Korea 2018, at booth A611.

Pickering’s new Series 120 4mm2 TM reed relay range (Figure 1) has attracted a lot of interest since being released in 2017 at Semicon West in San Francisco. The relays require a board area of only 4mm x 4mm, making it the highest packing density currently available, taking up the smallest board area ever.

Two switch types will be available, a general purpose sputtered ruthenium switch rated at 15 Watts, 1 Amp (3 Volt version) or 20 Watts, 1 Amp (5 & 12 Volt versions) and a low level sputtered ruthenium switch rated at 10 Watts, 0.5 Amps.

These are the same reed switches as used in many other long-established Pickering Electronics ranges but are orientated vertically within the package, allowing this very high density. The small size of the package does not allow an internal diode. Back EMF suppression diodes are included in many relay drivers but if they are not, and depending on your drive methods, these may have to be provided externally.Pickering Series 120 Reed Relays on PXI PCB

Figure 2: A total of 528 Series 120 relays on Pickering Interfaces ultra-high-density PXI module illustrates the packing density of these extremely small Reed Relays.

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. Relays of this small size without magnetic screening would be totally unsuitable for applications where dense packing is required.
