Keithley Instruments Inc. 3732 QUAD 4X28 REED RELAY MATRIX CARD
The Keithley 3732 is a Quad 4x28 Reed Relay Matrix Card designed for use with Keithley Series 3700A and 3700 System Switch/Multimeter mainframes. It provides a high-density switching solution with four independent 4x28 matrices, totaling 448 crosspoints. The card uses high-speed, long-life reed relays for reliable signal routing and supports signal levels up to 150V and 0.5A. The 3732 is ideal for automated test systems requiring high channel count and fast switching, such as semiconductor, board, and device testing. It features low contact resistance and minimal signal path capacitance for accurate measurements.
