Ideal for applications requiring a low number of channels and poles
Pickering's range of low-density PXI multiplexer switch modules are ideal for applications requiring a lower number of channels and poles. All modules are based on high quality ruthenium reed relays that switch up to 150V, 1.2 Amp with 20W max power or high quality electro-mechanical relays (EMR) that switch up to 300V, 2 Amp with 60W max power.
The range includes a low thermal offset multiplexer that is suitable for connecting to thermocouples and other sensors that require the use of contacts with low offset errors and consistent contact performance.

All the connectors used by these modules are supported by our range of cable and connector accessories.
