The NASA 401LA Low-Ambient Pressure Switch Kit is a sophisticated and reliable solution for monitoring the pressure conditions in various industrial and aerospace applications. This pressure switch kit is designed to operate effectively in low-pressure environments, making it an ideal choice for applications where the ambient pressure is below atmospheric conditions.
The NASA 401LA is manufactured using high-quality materials and advanced technology to ensure precise and consistent pressure sensing. The pressure element inside the switch is made of stainless steel, providing excellent corrosion resistance and durability. This material also ensures that the switch can withstand the rigors of high-vibration and high-shock environments, making it suitable for use in aerospace applications.
This pressure switch kit features a set point adjustment range of 0-20 psig (0-1.4 bar), and it can be easily adjusted using an external adjusting nut. The switch offers hysteresis of 2 psig (0.13 bar) and a repeatability of 0.5 psig (0.03 bar), ensuring accurate and stable pressure detection.
The NASA 401LA is designed to be compact and lightweight, with a size of just 3.1 x 2.1 x 1.0 inches (7.9 x 5.3 x 2.5 cm). It comes with a wiring configuration that includes normally open (NO) contacts and a terminals for a 250 ohm external resistor. The switch also features a prominent red indicator LED, which illuminates when the pressure reaches the set point, providing a clear visual indication of pressure status.
The NASA 401LA Low-Ambient Pressure Switch Kit is suitable for use in a wide range of applications, including fuel cell systems, pneunatic systems, and vacuum systems. It can also be used in aerospace applications such as spacecraft, missiles, and unmanned aerial vehicles (UAVs). With its advanced features, high-quality construction, and easy-to-use design, the NASA 401LA is the ideal choice for anyone who needs a reliable and accurate low-ambient pressure switch.
