National Instruments NI-9945 Terminal Block
The National Instruments NI-9945 (Part Numbers: 194739-01, 194739-02) is a reliable terminal block that makes it possible to add a quarter bridge to the NI-9237 strain bridge input module. The NI-9945 terminal block allows you to achieve precise measurements and accurate data acquisition. The NI-9945 can be used with shielded cables, allowing for optimal signal termination with minimal noise interference. Part number 194739-01 is the standard version of the terminal block, while part number 194739-02 refers to the high accuracy version.
To ensure that the NI-9945 is installed properly, you need to securely wrap a plastic tie strap around the front two hole of the devices for strain relief. You will also need an M4x20 screw that can comfortably fit into the 8.89 mm outer and the 4.57 mm inner clearance holes.
With a temperature range of -40 °C to 70 °C, the NI-9945 Terminal Block offers consistent performance across a variety of environments. It features a resistor value of 350 Ω, allowing it to enhance the capabilities of your strain bridge input module. With a resistance drift of only 0.0035 Ω/°C, measurements remain stable and accurate over time. The resistor tolerance of the NI-9945 is set at a maximum of 0.1% at 25 °C, which guarantees that your applications receive precise and reliable data. Additionally, the NI-9945 features a maximum resistor power of 0.25 W.
The NI-9945 Terminal Block provides an efficient and space-saving solution without compromising performance. It has dimensions of 2.6 in. × 0.85 in. × 0.90 in. and weighs a mere 1.1 oz.
