Big switch matrix has solid (state) benefits

Solid state matrix offers a perfect solution for applications that benefit from the characteristics of solid-state switches and large matrix requirements.

Pickering Interfaces is expanding its range of PXI switch matrix solutions with the introduction of a new solid-state switching version of the BRIC, the 40-563.

The new solid state matrix is available in two-, four- and eight-slot BRICs and offers a perfect solution for applications that benefit from the characteristics of solid-state switches and large matrix requirements.

Each solid-state switch in the 40-563 has a continuous current rating of 0.2A and can sustain inrush currents of 0.75A for 100ms.

The switches ensure fast rise and fall times of typically 20ms without contact bounce.

Each switch has a typical on resistance of 0.8ohm, providing a typical path resistance of less than 2.5ohm between x-axis connections.

The 40-563 is available in matrix sizes from 64x8 to 384x8.

Other configurations can be supplied on request.

These solid-state matrices are particularly suitable for applications requiring hot switching as the FET-based switches can sustain short-term inrush currents and full-load operation without any degradation in operational life.
