National Instruments 4DB50F-LFH160F Switch Cable

The 4DB50F-LFH160F (part numbers: 780009-01, 780009-02) is a versatile Switch Cable from National Instruments. Designed to assist with signal routing between DUTs (Devices-Under-Test) and various instruments, this cable is especially useful for connecting with National Instruments PXI Multiplexer Switch Modules such as the PXI-2576 and the PXI-2530B. The difference between the two part numbers of the 4DB50F-LFH160F is that part number 780009-02 measures 2m in length.

One end of the 4DB50F-LFH160F switch cable features a Female Low-Force Helix Connector with 160 pins, while the other end of the cable is split into four individual Female D-SUB Connectors which are each equipped with 50 pins. These D-SUB connectors allow the 4DB50F-LFH160F to easily connect with multiplexer switch modules, offering versatile functionality for a variety of test and measurement applications.

The maximum voltage of the 4DB50F-LFH160F cable is 100 VDC, measured according to Category 1 specifications. Designed for indoor use only, the switch cable achieves optimal performance when operated in temperatures ranging from 0 °C to 55 °C. When not in use, the cable can be safely kept in a storage environment where the temperatures range from –20 °C to 70 °C. For both operating and nonoperating conditions, the 4DB50F-LFH160F should be kept in environments where the noncondensing relative humidity ranges from 5% to 85%. The cable can be used at altitudes up to 2,000 m, and it has a pollution degree of 2. The 4DB50F-LFH160F switch cable weighs in at 1088.6 g (38.4 oz).
