Hello SRI-News Readers,

We are celebrating our fifth year of our newsletter publication and to help us celebrate, we are still offering 5% Discount on All NTE Orders Over $25 for the month of May.

This Month's Article - Resistors, They come in all Shapes
and Sizes

We overlook them at times but resistors are the nuts & bolts of any circuit board. As the name implies, resistors reduce (or resist) the flow of electrical current from one region to another. The amount of resistance to the flow of current that a resistor causes depends on the material it is made of as well as its size and shape. With all the resistor manufacturers and types available, it can be difficult to decide which resistor is right for a certain application. This article describes some common resistors, their properties, identification methods, and the applications they are used for. Learn More!

Manufacturer of the Month - Meltric
Meltric offers a broad range of multipin devices for use in a wide variety of control and power applications. Meltric's multipin connectors can replace Amphenol, ITT Cannon, Cinch, and other multipin connector lines. Each multipin device features spring-loaded, silver-nickel butt-style contacts and casings made of fiberglass reinforced thermoplastic polyester, epoxy coated zamak, (a zinc-aluminum alloy) or stainless steel, depending on the model type and size. Products are available with as many as 37
or as few as 4 contacts. Products range from 5A up to 150A and some include load making and breaking capabilities.
  • PN multipin plugs and receptacles are ideal for compact applications in robotics, machine tools, and food processing.
  • DSN multipins are designed for frequent low ampacity connecting and disconnecting applications.
  • DN multipins are excellent for those difficult environments where there is a need for frequent non-load break connecting and disconnecting.
  • DS7 and DR7 multipins are made for the same difficult environments as DN7. As an added feature, they allow customers to add up to 3 pilot contacts.
  • Spring-loaded, butt-style, silver-nickel contacts perform in harsh environments over thousands of operations
