While some setups can do everything they need to with simple, binary commands, others require more fluid adjustment to fit shifting tasks. One component that is well-suited to facilitate this type of control is a potentiometer. If you are looking to learn more about potentiometers for your own builds, read on as we cover all the basics of how they are constructed and a few of their typical tasks in this blog. Read more >>

Despite Del-Pro Corp being a defunct manufacturer, some of their products are still in-demand for the purpose of maintaining older electronic and electrical systems. Identifying reliable sources for out-of-production components like theirs is always a challenge for procurement teams, but luckily, many Del-Pro Corp offerings were assigned NSNs as a result of their employment in government operations. The technical specifications of any NSN-designated parts will remain documented on numerous databases, making it far easier to locate outdated stock or identical components produced by alternative manufacturers. This guide will take you through a small array of the Del-Pro Corp parts you can expect to come across on procurement platforms and some tips for sourcing fitting replacements.

A Look at Some Del-Pro Corp Part Numbers

Most Del-Pro Corp part numbers were assigned under Federal Supply Group (FSG) 59 - Electrical and Electronic Equipment Components, and more specifically, Federal Supply Class (FSC) 5905 - Resistors. Notably, most of their part numbers presently listed on purchasing platforms are labeled as fixed composition resistors, including: Read more >>

Aircraft systems rely on tightly controlled fluid movement to support a wide variety of functions, as even minor disruptions in flow direction can lead to performance degradation or localized component stress. To address these challenges, valve components that fall under designated National Stock Numbers (NSNs) are often implemented to manage pressure conditions and restrict reverse flow within critical circuits. In this blog, we will be specifically going over NSN 4820-01-035-0612, as well as examine where valve parts and similar items are commonly used in aircraft applications.

Products That Fall Under NSN 4820-01-035-0612

NSN 4820-01-035-0612 is listed under Federal Supply Class (FSC) 4820, a category that encompasses nonpowered valve-related items used in fluid-handling systems. Components within this class typically operate without external actuation, instead relying on system pressure to perform their intended roles within fluid circuits. As such, products that fall under the aforementioned NSN are components of a larger assembly, rather than a standalone flow-control device. Read more >>

Industrial controller cable assemblies play a central role in automated systems by linking controllers, sensors, and equipment in a way that supports reliable signal transmission and coordinated machine operation. As automation environments can differ widely in scale, physical layout, and operating conditions, the specific function of these assemblies varies widely from one industry to another. In this blog, we will explore how industrial controller cable assemblies are utilized across key industries while examining the specific types of value they provide within each automation context.

How Do Industrial Controller Cable Assemblies Add Value?

In many manufacturing automation environments, controller cable assemblies play a supporting role in how control systems are installed, maintained, and adapted over time. Read more >>

Aircraft hydraulic systems are essential for modern assemblies and operations, engineered to supply the high-force power transmission that many mechanisms require but cannot achieve through mechanical or electrical means alone. Because these systems often support critical operations like flight control actuation, landing gear movement, and braking, they are designed to maintain consistent output under elevated pressures and demanding service conditions. In this blog, we will explore the components, operational functions, and maintenance practices that define hydraulic systems in aircraft, so read on if you are interested in learning more.
