LXI Low Thermal EMF Matrix 1-pole 14x33
60-510-004
The 60-510 is a high density 1-pole matrix module controlled via LXI. It has excellent thermal stability and substantially reduced thermal EMF figures when compared to a conventional switching matrix. Typical applications include signal routing in ATE, selecting thermocouple inputs, switching amplifier gain circuits and high accuracy DC micro-volt measurements. Ruthenium reed switches are used because of their good low level switching capability. They also have a very long life with excellent contact resistance stability, minimal wetting current and low thermal offset. The 60-510 is designed in accordance with the LXI Standard 1.4 and is supplied in a 2U high, full rack width case with 500mm depth.
